Hornby R4521 00 Gauge BR Gresley Suburban Semi-Corridor Lavatory Composite Coach in British Railways plain crimson livery.
These coaches were used on suburban passenger and many local passenger trains throughout the LNER network.
This model is the composite coach which contained compartments for first and third class passengers divided by a pair of lavatories. The coaches had an unusual 'semi-corridor' arrangement, allowing passengers to access one of the lavatories from any compartment using short side corridors, situated on opposite sides for the first and third class sections of the coach and not connected.
These coaches are ideal for short local passenger and branch trains, coupled with a brake third to provide accomodation for first class passengers in a short train.
