BRAKE AND SIGNAL EQUIPMENT

§ 91.106 Safe condition. (a) It must be known before each trip that the brakes on locomotive and tender are in safe and suitable conditions for service; that the air compressor or compressors are in condition to provide an ample supply of air for the service in which the locomotive is put; that the devices for regulating all pressures are properly performing their functions; that the brake valves work properly in all positions; and that the water has been drained from the air-brake system.

(b) Each steam road locomotive built on or after March 1, 1946, shall be equipped with a brake pipe valve attached to the front of the tender or on the rear of the back cab wall to enable the brakes to be applied in the event the occupants of the cab are, from any cause, prevented from applying the brakes in the usual manner. On locomotives having vestibule cabs the brake pipe valve shall be located adjacent to an exit. The words "Emergency brake valve" shall

be legibly stenciled on the cab near the brake pipe valve or shall be shown on a badge plate adjacent thereto. That each steam road locomotive built before March 1, 1946, shall be so equipped the first time said locomotive receives class 3' or heavier repairs after June 1, 1946, but not later than June 1, 1948. (Secs. 2, 5, 36 Stat. 913, 914, sec. 1, 38 Stat. 1192, sec. 2, 43 Stat. 659, sec. 1, 54 Stat. 148; 45 U.S.C. 23, 28)

That each steam road locomotive that takes water en route, built before March 1, 1946, shall be so equipped the first time said locomotive receives class 31 or heavier repairs after June 1, 1946, but not later than June 1, 1948. [Paragraph (a) amended]

THROTTLE AND REVERSING GEAR

§ 91.157 Reverse gear.

(c) Each steam locomotive used in road service, built on or after March 1, 1946, that has an air operated power reverse gear shall be equipped with a connection whereby such gear may be operated by steam or by an auxiliary supply of air in case of failure of the main reservoir air pressure. Each steam locomotive used in road service, built on or before March 1, 1946, that has an air operated power reverse gear shall be so equipped the first time said locomotive receives a class 3' or heavier repairs after June 1, 1946, but not later than June 1, 1948. If an independent air reservoir is used as the source of auxiliary supply for the reverse gear, it shall be provided with means to automatically prevent loss of pressure in event of failure of the main

reservoir air pressure. [Paragraph (c) amended]

(d) When steam connections to air operated power reverse gear are used, the operating valve handle shall be conveniently located in the cab of the locomotive and so arranged and maintained that in case of air failure steam may be quickly used to operate the reverse gear.
