HORNBY R30431 RailRoad: Class 73 Diesel Locomotive - BR - 73132

History from Hornby's website:

Introduced by BR in 1963, what is now known as the Class 73 is an electro-diesel locomotive, which are also referred to as EDs. 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.
