S-010(Former A-4A)

The requirements of these Standard and Recommended Practice specifications represent the minimum acceptable. All suppliers of products and materials are urged to exceed the intent of these requirements as much as possible. Many devices covered by the specifications have been developed through the help of extensive field experience and tests. Each specification contained herein should be read as including an additional requirement for satisfactory performance under a field test if such test is deemed appropriate after consideration by the Executive Director of the Mechanical Division and the A.A.R. Research Department working with the appropriate Mechanical Division Committee(s). When inspection of manufacturing processes or facilities of companies manufacturing car components for use on cars in interchange service involve travel of A.A.R. personnel outside the boundaries of the North American Continent, the out-of-pocket expenses involved to conduct such required inspections will be paid by the company offering such products for this service.

Association of American Railroads Mechanical Division Manual of Standards and Recommended Practices SPECIFICATIONS FOR THE CONSTRUCTION OF NEW PASSENGER EQUIPMENT CARS Standard

(Former Sect~on C) S-034

Adopted, 1939; Advanced to Standard, 1945; Revised, 1967, 1969 PREFACEThe specifications have been prepared on the basis that they will be used for structural design of future new equipment and that the requirements laid down therein will not be retroactive into equipment now in service which has been built to former accepted specifications.

BASIC FUNDAMENTALS, NEW SPECIFICATIONSThe Railway Mail Service Specifications as revised July 20, 1938, were used as the basis for these specifications which provide for cars which may be used in trains of over 600,000 pounds light weight made up of cars of any type of construction now being operated. The Committee's review of the latest Railway Mail Service Specifications resulted in the preparation of these specifications in such a way as to more definitely establish the strength values at various locations in the car, as follows: (a) Trucks are required to be locked to the car body. This is for the purpose of obtaining the value of the weight of the truck plus the shear value of the truck attachments to the car body under abnormal accidental impacts. (b) A car structure which resists minimum static end load of 800,000 lbs. applied on center line of draft without developing any permanent deformation in any member of the car structure. The minimum static end load of 800,000 lbs. was derived from a 400,000 lb. design load with an approximate factor of safety of 2. In meeting this requirement, it is important that vertical deflection be kept to a minimum.

Note:-As a guide in design, it is recommended that, for materials and forms of construction now used, the maximum vertical deflection measured at center of car and based on distance between truck centers should not exceed 1 inch. Normal vertical deflections for cars having approximately 60 ft. distance between truck centers from % to Y in. for steels and different forms of steel 4 constructions.(c) Cars must be designed to resist a horizontal load of 500,000 lbs. applied on the buffer beam at a point 12 in. above the center line of draft. This static load was derived from a 250,000 lb. design load employed in cars built to Railway Mail Service Specifications with an approximate factor of safety of 2. (d) Vertical strength requirements have been assigned to the buffer beam construction, the anti-climbing arrangement, and the coupler carrier arrangement. All these parts are to be designed to resist vertical loads of 100,000 lbs. These requirements are to resist coupled car ends from moving vertically with respect to each other under abnormal accidental impacts. (e) The two main vertical end members are required to have an ultimate shear value of not less than 300,000 lbs. each at a point even with the top of the underframe to which they are attached. This requirements was included to establish definite strength values at these points.

s-034


SECTION 1-SCOPE Application(a) These specifications have been prepared on the basis that they will produce passenger cars suitable for use with cars of all types of construction now in service and built in accordance with Railway Mail Service Specifications, with the result that new and existing cars will satisfactorily operate together with maximum protection under all conditions of service. These specifications provide that static end loading shall be applied through center line of draft but must not be construed as requiring the application of end loading on the center line of draft of existing cars constructed to Railway Mail Service Specifications.

A = area of column cross section, square inches. IT = 3.1416, constant.= =

Stresses described above as maximum allowable are contingent upon the ability of webs and flanges to resist these stresses without buckling. (c) For compression in the plane of any flat plate used as an element in the section the ability to resist buckling shall be checked and determined by substituting the following equivalent slenderness ratios in the formula applicable to the entire column: For outstanding flanges: (Flat plates supported along one edge in the direction of stress) Llr 5.0 bit.=

The constants 5.0 and 1.8 in the above expression for the equivalent Llr give a nominal safety factor of 2.0 on reasonably restrained edge condition. Constants between these may be selected depending upon the shape of the member and connections used. (d) Where metals other than mild rolled open-hearth steel are used, the car structure must be at least equal in strength to the stated specification requirements. The maximum allowable stresses shall bear the same relation to the stresses tabulated in this Section, as the yield strength of the metal used has to the yield strength of mild open-hearth steel, which for this comparison shall be taken as 32,000 pounds per square inch, but in no case, except bearing, shall the maximum allowable stress exceed 40% of the minimum tensile strength of such material. Cast metals shall be compared on same basis as structural metals; but the allowable tensile stress shall be limited to 80% of that allowable for rolled materials. (e) Where minimum section meduli or thickness are specified they shall be adjusted in proportion to the ratio of the yield strength of the metal used, to that mild open-hearth steel.

(0Where yield and shear loads are specified the size of members shall be based on the yield or ultimate shear strength of the materials employed.SECTION 21-SUBFLOOR The entire car shall have metal subfloor, flat or corrugated.

2. Each hand brake shall operate in harmony with the power brake and the design shall be such that with a force of 125 lbs. at the rim of the hand brake wheel or 3" from the outer end of handbrake lever, a force will be applied to the truck brake gear with sufficient effective power to stop and hold the car and provide a total effective brake shoe pressure against the wheels of not less than 25% of the total weight of the car on rail when the car is fully equipped and loaded to nominal capacity. (Nominal capacity for mail, baggage, milk, express and similar load carrying cars shall be their specified load capacity as usually stenciled in or on the car; the nominal capacity for passenger carrying cars shall be based on their seating capacity at approximately 150 lbs. per person, and for combination cars shall be the proper combination in accordance with their arrangement.)

3. When brake piston is in fully released position, there shall be no excess slack in the hand brake chain or other connections and provisions shall be made in the design for winding chain uniformly on drum without overlapping.4. Hand brake wheel to be designed so as to prevent trainmen from reaching through between spokes to operate ratchet lever. Openings to be of sufficient depth, preferably 3% in. and not to exceed 4 in. to provide grip on rim with gloved hand.

5. Hand brake lever, when applied to outside face of end of car shall operate in a vertical plane and parallel to end of car.

7. The angle of contact between ratchet pawls and their teeth must be such that the pawl cannot slip when a pull is exerted in the direction of operation and must be anchored to their supports so as to hold brake applied to any degree.8. Ratchet operating lever, where used, is to be arranged to travel in vertical plane and to throw to left facing hand brake when in applied position and to the right for release. Operating lever should preferably be horizontal but in all cases within 45 degrees of horizontal when in applied position. Movement of lever to be limited insofar as practicable, but when in release position, should be sufficiently off vertical center to automatically release the pawl from ratchet wheel when the brake wheel or hand brake lever is moved in direction of application sufficiently to release the pawl of entire load. Positive connection is to be provided between the operating lever and pawl so that the pawl may be forced to application position by hand when necessary. 9. Foot operated brake pawl must be so designed and located as to provide positive operation without interference under all conditions.10. Hand brake wheel or hand brake lever and drum or brake shaft shall be arranged so that both will revolve when applying and gradually releasing the hand brake.

Any efficient means for changing direction of pull may be used. Sheave wheels, where used, must be not less than 4 in. diameter, preferably 6 in.

Association of American Railroads Manual of Standards and Recommended Practices INSPECTION AND MAINTENANCE OF PASSENGER CAR HAND BRAKES Recommended Practice Adopted, 1937

(Former Sect~onE) RP-024

1. When the hand brake is applied tightly, all brake shoes must be brought into solid contact with the car wheels. Hand brakes which when in proper operating condition otherwise do not have sufficient effective power to provide for this must have such corrections made as are necessary to meet this provision. 2. Hand brake wheel or lever, when fitted directly to brake staff or operating shaft, must be tightly secured so that both will rotate in unison when moved in the direction of brake application.3. Gears used in transmitting power from an operating shaft to brake staff, winding drum or similar arrangement, must be securely fitted and be maintained to mesh properly together to avoid slipping.

4. Hand brake wheel or lever connected to brake staff or operating shaft with a ratchet arrangement must be maintained so that this ratchet (distinguished from hand brake ratchet), operates freely and its pawl is snapped snugly into the ratchet teeth by a suitable arrangement. The angle of contact between the ratchet pawl and teeth must always be maintained so that the pawl will not slip when a pull is exerted in the direction of brake application.

5 . Hand brake pawls and ratchets must be maintained so as to safety and securely engage when the brake is applied, and must be anchored to brake staff, drum or support so as to hold the brake applied to any degree and they must be maintained in proper position and operate freely.6. The brake staff together with its brackets, bearings and housings, must be maintained securely in position to avoid lost motion, misalignment and undue friction. Where brake staff bearings are subject to accumulation of dirt or other foreign matter or where staff passes through end sills or other parts of car structure, the openings must be large enough to be self-cleaning or readily cleaned.

7. Hand brake chain slack shall be sufficient and not materially in excess of the amount required to provide for properly connecting the hand brake rigging when all parts are in their full release position. Hand brake chain hangers, or carriers must provide clearance or bearing surface to prevent chains fouling and developing undue resistance to movement.

f

To apply to installations on future new cars and on existing cars as cars are shopped for scheduled repairs. Recommended Practice Adopted, 1945; Corrected, 1949

t

1. Remove conductor's and car discharge valve cords from body of passenger train cars, excluding such cars as listed above.

2. Cars from which the conductor's and car discharge valve cords have been removed from the body to be equipped with one conductor's and one car discharge valve at one end of the car. On cars on which there is no attendant regularly assigned it is desirable to have a conductor's and a car discharge valve at each end of car so the valve can be readily operated without the necessity of the trainmen having to travel the length of the car. This application of the second valve to be optional with the individual railroad. 3. The conductor's valve to be suitably located at the end of the car in locker, toilet or on partition depending upon the construction or arrangement of the car, but so placed that the valve handle can be operated from inside passageway of car. Car discharge valve on vestibule cars should be located in vestibule on end post or other suitable location and provided with cord to permit operation of valve from either vestibule or inside of car near end door. Car discharge valves on cars not equipped with vestibules should be located on end door post, telescoping plate or other suitable location outside of car and should be provided with cord extending into car near end door to permit operation from inside of car.4. A shield or cover over the handle of the conductor's valve has been found desirable by a number of railroads, and the use of same over the valve handle greatly minimizes malicious tampering.

5. Application of conductor's and car discharge valves on observation car platform to be in accordance with RP-021 of the Manual of Standards and Recommended Practices.

Association of American Railroads Manual of Standards and Recommended Practices LOCATION OF CONDUCTOR'S VALVE AND CAR DISCHARGE VALVE CORDS OR ATTACHMENTS ON CARS HAVING OBSERVATION PLATFORMS Recommended Practice

(Former Sect~on E)

RP-021

Adopted, 1932; Corrected, 1949Remove from the observation platform of all private or business cars, parlor cars and other cars having observation platforms, the conductor's valve and car discharge valve located over the window under the hood, and also cords or other attachments accessible from the observation platform attached to such valves inside the car. Locate the conductor's valve and car discharge valve on the rear platform railing as shown in Figure 1, the latter to be so located that the operating lever may be reached from the ground or from the platform. Attach to the branch pipe leading to the conductor's valve a suitable branch pipe equipped with operating valve and signal whistle, the conductor's valve to consist of a branch pipe from the main brake pipe reaching close to the top of the railing with a suitable stop cock for opening and closing same. On cars equipped with sliding coupler carriers, the connection to the brake pipe and signal pipe should be made far enough forward so that the branch pipe connects to a rigid section of the brake pipe and signal pipe.
