This RailRoad Class 73 diesel is based on a locomotive used for both passenger and freight trains over the years, so it is suited to many model railway layouts. 
It comes DCC-ready with a 21-pin plug, so you can upgrade it to run on DCC or with our HM7000 Bluetooth-controlled system, which also includes sound via a speaker inside the locomotive.
Introduced by BR in 1963, what is now known as the Class 73 is an electro-diesel locomotive, also referred to as an ED. As well as operating on the Southern Region’s 650-750v DC third-rail network, these locomotives have a 600hp diesel engine, allowing them to work over non-electrified routes and into sidings and yards where there isn’t a third rail power source. 
From new, all 49 locomotives were fitted for push-pull working with Southern Region multiple units.
