pouches, sacks or parcels. Use the back of pages, if necessary, for the listing. At the bottom left of page, below the diagram, the effective date will be shown and on the right, the diagram number. Diagrams will be produced by mimeograph, duplimat or other process until a new form on duplimat masters has been furnished on 8x101⁄2 paper. Diagrams will be prepared only after coordination between origin, intermediate, and destination regions.

Forms

(c) Individual car diagram. 5045 and 5046 will no longer be used. A supply of diagrams as prepared in accordance with (b) of this subdivision (ii) will be furnished to the transfer office for placement in each car moving, in lieu of Form 5045. An individual car diagram will reflect changes in separations designated in the official loading diagram only if necessitated by variance in the volume of mail loaded by days of the week. The transfer clerk will use this form for updating and reporting corrections in the published diagram separations.

dia

(d) Review. Official loading grams will be reviewed for correctness at frequent intervals by the director, transportation division, and by transfer clerks, to insure that service needs are met, train schedule changes are met, loadings and dispatches of value are being obtained, designated separations are based on actual postal needs, and maximum use of doorways for mail is made.

(iii) Separations-(a) Definition. A separation is a designated piling of mail segregating such piling from other mail in a car. It may be specific or mixed or jackpot.

(1) Specific. A specific separation is one which will not be further separated between the points of loading and dispatch of the particular separation.

(2) Mixed or jackpot. A mixed or jackpot separation consists of small separations which are combined at the point of loading to be re-separated on route by railroad personnel.

(b) Classification of s e parations. Separations will be classified by the director, transportation division, as necessary for postal needs, or requested by the railroad.

(1) Designated separation. A designated separation will be established when it is necessary to the needs of the postal service, in the light of volume and/or service. Any separation needed

to effect the most efficient and expeditious postal delivery will be designated as necessary to the postal service.

(2) Railroad separation. In those instances in which a working car is not accompanied by a train baggageman or mail piler, so that no separating is performed en route, the carrier may request the establishment of separations for its own reasons, such as to expedite schedules, or improve the use of facilities or manpower. If the director, transportation division, approves a railroad request for the establishment of such separations, they will be indicated on the official loading diagram, and, the individual car diagram, and, in each instance, such a separation will be marked "RR” and the mail therein theoretically combined with the other separation or separations for the same point in computing line haul space credits.

(c) Observance of designated separations. Mail loaded into working cars for dispatch at intermediate or terminal points will be placed in separations designated on the individual car diagram.

(d) Railro a d responsibility. Railroads are responsible for the proper loading and unloading of mail, and the maintenance of designated separations in accordance with the individual car diagram and instructions issued by the director, transportation division, and his representatives.

(e) Partially filled separation. When the volume of mail for a designated separation does not fill a separation, such separation will be maintained and paid for.

(f) Review. The director, transportation division, and transfer clerks will, at frequent intervals, review designated separations which are required and maintained to meet the needs of the postal service and will determine whether additional separations should be established, and whether established separations can be discontinued as no longer necessary for postal needs. Transfer clerks will report conditions warranting the establishment or discontinuance of a designated separation to the director, transportation division, who will, after approval, notify the railroad mail transportation officer of such change, in advance of its effective date.

(3) Spacing-(1) Destination and destination relay cars. Originating postal regions are responsible for proper spacing of destination and destination relay cars for compensation purposes. Sub

ject to the opening of a destination relay car at a relay point for necessary loading or unloading, such cars shall not be opened except under the conditions outlined in paragraph (i) (4) (iv) of this section, and in cases of emergency. Exception to the origin spacing for the purpose of administrative corrective action may be raised only at point of relay or destination by the region having jurisdiction of such point. The postal representative taking such exception shall immediately advise the local railroad representative of the loading condition of the car and the action taken. A comprehensive report of an exception shall be made promptly to the region at point of origin for corrective action.

(ii) Working storage cars. In working storage cars line haul space shall be determined on the basis of the linear feet of space occupied by the mail and computations of space occupied shall include the aisle space necessary to provide access to each designated separation. Such footage allowance shall be based on the floor space occupied by officially required separations, with due regard to unnecessary spreading of the mail and lack of stanchion poles. Space available in the working storage car must be fully utilized before duplicate separations are made in other cars of the train.

(4) Weight limitations—(i) Requirements. A 60-foot storage car with a weight-carrying capacity of not less than 60,000 pounds or 1,000 pounds per linear foot is required. Storage cars provided by railroad companies for regular movements of mixed mail shall be capable of loading to 1,000 pounds per foot or to their full cubical capacity whenever mail is available.

(ii) Observing limitations. Car weight capacity limitations must be observed in all loadings, when a railroad company stops loading a car because of weight limitations before the cubical capacity is reached, pro rata footage shall be allowed for the mail in the car. The footage shall be based either on the space occupied by the mail as compared to a fully loaded 60-foot storage car, or the approximate weight of the mail as compared to the weight-carrying capacity of 60,000 pounds, whichever is greater.

(iii) Loading stopped for weight limitations. When the loading of a car is stopped because of weight limitations, the car placard and Form 5118, Line Haul Mail Storage Service and Related Terminal Services shall be endorsed WT.

LMT. Notation should appear also as to the approximate weight of the mail involved, with special report of further details as warranted.

(e) Failure to move mail in regularly designated train—(1) Service by other than regularly designated train. When for operating reasons or because of delayed connections a railroad transports mail on a different train than that on which the same railroad has been designated to carry it, the mail will be charged to the train on which actually carried. When a railroad desires to forward mail on a train not due to receive it from one station to another station for dispatch from the latter station, permission may be granted with the understanding that the movement shall be without additional compensation and that no delay will result to the mail.

(2) Overtaken train. When one mailcarrying train is overtaken by another and mail is combined and forwarded from that point in a single train, payment will not be allowed for the nonmail-carrying train beyond the merger point.

(3) Missed connections. Where mail misses connection and there is no representative of the Postal Service to authorize movement of such mail, the railroad company may carry the mail on an undesignated train that can be used to advantage.

(4) Fast and local train. When, for postal service reasons, mail is delivered by fast train at a certain point from which it is forwarded or returned on a local train to a local point, payment will be allowed in both trains between appropriate points. When mail is dispatched on a local train from a local station and delivered to a fast train at a certain point, payment will be allowed in the local train between appropriate points and in the fast train from point of receipt.

(f) Classes of service—(1) Storage car service-(i) Scope of service. Service of this class shall be requested in units of 60 feet in length, inside measurement, except as hereinafter provided, used exclusively for mail. This service is the transportation and handling of made-up mail in bulk and the requirements for this service shall include the maintenance and cleaning of the cars. The handling of mail into and from all storage cars shall be performed by employees of the railroad companies under

instructions of postal employees with respect to proper routing and separation of mail. (Comprehensive Plan.)

(a)

(ii) Operation and payment. Storage car service shall be requested and paid for in one direction only between established railway passenger or freight division points or junctions at which the train is scheduled to stop; except that a destination storage car or a destination relay storage car originating or terminating at a point between established division of junction points shall be considered as originating or terminating at the intermediate point for the purpose of compensation. (ICC)

NOTE: This provision does not involve ascending or descending loads which are governed by the proviso for maximum volume between junctions as stated in paragraph (h) (6) of this section.

(b) Storage car service shall be paid for in units of 60 feet in length, inside measurement. (ICC)

(iii) Junctions. For the purpose of compensation for storage car service, points upon a carrier's own line where its tracks, upon which mail carrying trains are operated, cross or diverge, shall be considered as junctions. Where two or more railroads participate in joint operation, the junction shall be considered common to all railroads so participating. (ICC)

(iv) Advance notice when car not needed. (a) Whenever there is insufficient mail on any day to warrant the operation of an exclusive storage car which would otherwise be required to accommodate the normal load, the request for such car may be canceled by a representative of the Post Office Department at the initial point of the run of the car. Reasonable advance notice of such cancellation shall be given to the railroad company at the initial point of the run of the car to permit the car to be removed from the train. (Comprehensive Plan.)

(b) If the car is removed and the mail is transferred to other space in the train at the direction of the local postal representative, an additional terminal charge will become due.

(2) Lesser storage unit service—(i) Size. Lesser units of storage space service shall be paid for in units of 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30 linear feet without duplication or grouping. (ICC)

(ii) Scope of service. Service of this class shall be requested in the established less than full-car units of space in mixed

traffic, combination, or other cars. This service shall be the transportation and handling of mail of the same type as that handled in storage car service. The requirements for lesser storage unit service are the same as for storage car service. (Comprehensive Plan.)

(iii) Operation. Lesser units of storage space shall be requested and paid for in one direction only. For the purpose of compensation under the rates prescribed, lesser units of storage space may begin at the point where storage space becomes necessary and may be terminated at the point where the last mail is dispatched, but they shall not be changed en route at other than established railway passenger or freight division points or junctions. (ICC)

(iv) Junctions. For the purpose of making changes en route in lesser units of storage space, points where two mail carrying lines of the same or of different railroads cross or diverge and at which mail is regularly received or dispatched by any train shall be considered junctions, whether or not there is a physical connection between the lines of railroad at such points by switch or otherwise. Points on parallel lines shall not be considered junctions except where the lines converge or diverge. (ICC)

(v) Railroad and electric car lines. Points of intersection between railroad lines and electric car lines are not considered as junction points.

(vi) Performance. Lesser storage unit service may be performed independently or in conjunction with storage car service.

(3) Basis for determining linear feet of lesser storage units—(i) Biennial bin test. The Postmaster General, upon notification to the railroads and with their presence and assistance, shall conduct tests at least once in 2 years to determine the number of sacks and outside parcels that will fill 3 linear feet of space, both sides of a car, and the results thereof shall be reflected in changes, when necessary, in the count of sacks and outside parcels as the basis for measurement of lesser units of storage space, except that in exceptional cases lesser units of storage space of 15 feet or over may be determined by measurement when mutually agreed upon by the Department and the railroad. In no case shall payment be made for more space than the inside length of the car or compartment. (ICC)

(ii) Conduct of test and application of test results. The Department selects the test period, and will issue specific instructions in regard to the manner of conducting the tests, when each period is announced. The results of the test shall be stated in terms of a national average to be applied uniformly. Effective June 23, 1962, 52 pieces equal a 3-foot unit.

(iii) Basis for determining lesser unit. The number of linear feet needed on both sides of baggage, storage or oversize RPO or apartment cars for carrying the mail in lesser storage units of 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30 feet shall be determined on the basis of the number of pieces (sacks and outside parcels combined) that will fill 3 linear feet of space on both sides of the car as determined in the last biennial test. Where the space unit is determined by count, each box of baby chicks shall be considered equivalent to one piece.

(g) Method of determining mail load-(1) Several cars. Where mail is carried in several cars in a train the total volume of storage mail in the train shall be determined by adding the volume transported in storage service in all cars operating in the train, including destination and destination relay cars.

(2) Determination of volume in car. The volume of mail in a car must be determined by:

(i) Count. Count, when the linear feet of space occupied by the mail is 30 feet or less.

(ii) Measurement, over 30 feet. Measurement, when the linear feet of space occupied by mail is more than 30 feet.

(iii) Measurement, 15 feet or more. Measurement, in those cases where the linear feet of space occupied by the mail is 15 feet or more, and mutually agreed to by the Department and the railroad.

(iv) Measurement, fully loaded. Measurement reflecting the inside length of a car or compartment of a car when the car or compartment is fully loaded.

(3) Count versus footage computations. Where the mail in a car exceeds 30 feet by count, but actually occupies 30 linear feet or less of space, the volume of mail is considered as 30 feet. Once the unit of space has been determined as 30 feet, such unit must be considered to be theoretically filled. Any additional mail added to that carried in the car shall be added to the 30-foot arbitrary unit. If there is a net increase in mail loaded at

intermediate points between division or junction points, it will be added to the 30 feet, making it necessary to respace the car and allow credit for the maximum footage carried between the division or junction points.

(4) Measurement and count cars. Where mail is carried in two or more cars operated in the same train, some cars on the measurement basis and others on the count basis, total all pieces in the count cars, convert to feet and combine with footage in other cars to determine volume carried in the train. Cars computed in accordance with subparagraph (3) of this paragraph will be considered as measurement cars.

(5) Computation of working storage car space. (i) Piece count shall be used to determine the space credits until the space occupied by the mail exceeds 30 feet after which spacing shall be determined on a visual linear measurement basis with proper consideration being given to the allowance due in accordance with paragraph (d) (1) (ii) of this section.

(ii) To determine the volume of mail for line haul space credits in working storage cars between junction points, the count equivalent to the visual linear footage at the earlier junction point shall be adjusted by adding the mail loaded and subtracting the mail unloaded by pieces at each intermediate point as indicated on the train baggageman's report. (See paragraph (h) (6) of this section.) Line haul credits leaving each storage car junction point at which a transfer clerk is on duty or, by mutual agreement, any other point on the run at which the car exchanges mail, shall be re-evaluated on the basis of the count equivalent of the footage reported in Column 13 of Form 5118. This count equivalent of the re-evaluated space occupied by the mail shall be substituted at that point for the adjusted count equivalent referred to above and shall stand as the base count (subject to adjustment as indicated above) to the next re-evaluation point. When the count equivalent reduces to 30 feet or less and the actual count is 30 feet or less at a re-evaluation junction point, actual count will be used for spacing.

(iii) Variations in count of mail loaded or unloaded as against train baggageman's report must be resolved by:

(a) Making an actual recount immediately, or

(b) Notifying destination, by telegraph or telephone, to have an actual count made on arrival of car.

In addition, spot checks will be made at destination on an irregular, random basis to determine accuracy of the mail count on the train baggageman's report. All checks will be made jointly by postal and railroad representatives and may be requested by either. Such variations will be reported by the transfer clerk under comments on Form 5366, Report of Mail Arriving-Leaving, and Form 5118.

(h) Method of computing storage linehaul payment (1) Source documents. The data to be used in determining linehaul pay will be obtained from Forms 5012, Mobile Unit Trip Report; 5061, Statement of Mail Loaded in Storage in lieu of RPO Space; 5118, Daily Report of Line Haul Mail Storage Service and Related Terminal Services; 5366, Report of Mail Leaving-Arriving; copies of train baggagemen's reports, and other pertinent service records.

(2) Total volume on train. For the purpose of compensation, the total volume of mail transported in a train in storage service between established railway passenger or freight division points or junctions shall be determined by adding the volume of such mail transported in all cars operating in the train, including destination storage cars and destination relay storage cars. (ICC)

NOTE: The footage of mail in destination and destination relay cars is used for line haul purposes-not the inside length of the

cars.

(3) 30 feet or less. Where the total volume of mail transported in a train in storage service between established railway passenger or freight division points or junctions does not exceed 30 feet, payment shall be made for the appropriate lesser unit of storage space needed to accommodate the mail. (ICC)

(4) 30 to 60 feet. Where the total volume of mail transported in a train in storage service between established railway passenger or freight division points or junctions exceeds 30 feet and does not exceed 60 feet, a footage prorate of the 60-foot storage car line-haul rate shall be paid for the footage transported. (ICC)

(5) More than 60 feet-(i) Standard. Where the total volume of mail transported in a train in storage service between established railway passenger or freight division points or junctions

exceeds 60 feet, the total footage of such mail shall be divided by 60 to determine the number of storage car service units of 60 feet for which payment shall be made. Whenever the residual footage does not exceed 30 feet, payment shall be made for the residual footage at the rate applicable to the appropriate lesser unit of storage space service. Whenever the residual footage exceeds 30 feet, a footage prorate of the 60-foot storage car line-haul rate shall be paid for the residual footage.

(ICC)

(ii) Exceptional. In those exceptional circumstances where the volume of mail transported in a train is carried solely in solidly loaded destination and/ or destination relay storage cars, no other mail space is available and the volume of mail exceeds 60 feet or even multiples thereof, payment shall be allowed for no more than the maximum mail footage furnished and used as follows:

(a) When the residual footage exceeds 30 feet, it will be stated as the appropriate prorate of a 60-foot car.

(b) When the residual footage is 30 feet or less, the appropriate lesser storage unit will be allowed, provided the inside length of the solidly loaded car or cars is equal to a 60-foot unit or units plus an exact lesser unit of storage space.

(c) When the residual footage is 30 feet or less, and the inside length of the solidly loaded car or cars is not equal to a 60-foot unit or units plus an exact lesser unit of storage space, the 60-foot unit or units plus the prorate of the appropriate lesser unit of storage space will be allowed.

Examples: (1) A fully loaded 70-foot destination car is the only mall space available in the train-allow a 60-foot car and 12ths of a 12-foot lesser unit;

(2) Two 40-foot fully loaded destination cars are the only mail space available in the train-allow a 60-foot car and 2921sts of a 21-foot lesser unit.

(6) Maximum volume. Payment for a lesser unit of storage space and a footage prorate of the 60-foot storage car line-haul rate shall be made on the basis of the maximum volume of mail transported between any points between established railway passenger or freight division points or junctions, as defined herein for lesser units of storage space service and storage car service, respectively. (ICC)

(7) Mail carried by in error. Mail carried by a station in error by a railroad
