The Ball handle is ideal for a selection of units and locomotives. Its also great to be used as a generic handle.
Perfect for the Networker, Electrostar, and Turbostar range of UK units. The Hill hold version features a flexible wire which plugs into the rear of the PBC unit to provide a hill hold/brake hold feature for any trains that support it in the simulator.
Features a latch on the rear of the handle to secure it to the metal PBC handle shaft. The latch should be down when placing on removing the handle, and moved up to secure it.
Modelled on the UK IET (Intercity Express train). Larger than the T-bar handle below. Sits at a slight angle just like the real thing.
Smaller than the chunky IET handle.
