This supply is a rejuvenation of one provided several years ago, but with current components.  It is designed to replace the existing battery used to operate the horn and some other limited applications in post-war Lionel applications.

Connections: The supply has three wires to connect to the center rail, outside rail, and battery connection on the relay.  Details provided in the accompanying instructions.   Mounting is via a double-sided tape.  This approach supports future removal if necessary.

Full instructions with photos provided.  But let’s be honest, given the opportunity just about anybody can mess things up!  Usual installation time is about 15 minutes.  If you are already familiar with how the existing battery, relay, and horn work this installation is very straight forward.  If all else fails, read the instructions provided!
