AIR-BRAKE EQUIPMENT 



2 Driver-brake cylinders of specified size and type. 

 1 Auxiliary reservoir of size required; for driver-brake 

 cylinders. 



1 Brake-pipe air strainer, 1 in. X 1 in. X f in. 



2 Reservoir drain cocks of size required. 



P-l (H-24) or F-2 (F-46) plain triple valve, 

 f-in. nipple; for triple valve, 

 f-in. cut-out cock; for triple valve. 

 Engine-truck brake cylinder of specified size. 

 Auxiliary reservoir of size required; for truck-brake 



cylinder. 



Hose connection, 1 in.X22 in., with ^-in. fittings. 

 3-in. cut-out cock; for truck-brake cylinder. 



This equipment was for an engine with a truck brake and 

 apparatus required for equipments using high and low pressures, 

 but it has been superseded by the ET equipment. The fixtures 

 included in the AG equipment, by the use of which it is possible 

 to use two standard brake-pipe pressures and change from one 

 to the other at will, are common to the high-speed brake equip- 

 ment and to the double-pressure control, schedule U. 



To secure complete high-speed brake equipment for an engine, 

 including truck brake, use schedule AG and one high-speed 

 reducing valve of size required. To secure complete double- 

 pressure control brake equipment for an engine, including 

 truck brake, use schedule AG and one E-l safety valve. 



Cut-out cocks for driver-brake cylinders, for driver-brake aux- 

 iliary reservoir, or for truck-brake auxiliary reservoir are not 

 regularly furnished; if wanted, they should be specified. 



This schedule provides for a truck brake operated in con- 

 junction with the driver brake. If independent operation is 

 desired, there should be ordered in addition a plain triple valve 

 and a brake-pipe air strainer. Also the cut-out cock should 

 be increased from $-in. to f-in. 



SPECIAL LOCOMOTIVE BRAKE EQUIPMENTS 

 Engine-Truck Brake. The additional parts required to 

 equip with an engine-truck brake an engine that is already 

 provided with ET equipment are as follows: One engine-truck 

 brake cylinder of specified size, one J-m. cut-out cock, with 

 choke fitting, one hose connection l-in.X22-in., with $-in. 

 fittings, complete. These are all classed under schedules 

 D-68, D-87, D-1,010, D-812, D-1,012, D-108, D-128.
