Hornby OO LNER Mk3 Trailer Std 42110

In-order to allow running at 125 mph on Britain's Victorian era railways, new rolling stock was needed by British Railways. Significant improvements over the Mk2 included new secondary air suspension between the bogies and the coach body as well as aerodynamic skirting on the underframe. Mk3 coaches are 75ft (23m) long enabling far greater capacity than older coaches.
