A tappet valve arrangement for a railway car coupler having a main valve for supplying air pressure from one railway car to another coupled railway car. A piston and cylinder valve for supplying air pressure to a coupler centering device when the railway is in an uncoupled state and for interrupting the flow of air to the coupler centering device when the railway car is in a coupled state. A negating spool valve for overriding the flow of air to the coupler centering device when the railway car is in an uncoupled state. A shut-off valve for interrupting the supply of air from one railway car to another railway car when it is desired to uncouple the railway cars.
