Gresley LNER 51' 1" Non Vestibule Pack (Non Corridor) Overview
These coaches of the London North Eastern Railway were built from around 1925 to almost the second world war in some cases. They lasted in BR passenger service into the early 1960's. They were designed by Sir Herbert Nigel Gresley (CME of the LNER). Referred to as Non Vestibule by the LNER (The LNER referred to all non corridor connected stock as Non Vestibule).
Based on Gresley's successful designs of teak Non Corridor carriages for the Great Northern Railway, they shared many features. Built to two widths, either 9 foot or 9'3". One interesting diagram is the Dia 50 Composite Lavatory Semi Corridor which had two corridors connecting to the centrally located lavatories. These were intended for longer suburban and cross country traffic.
An Ex NER Dia (Y)178 Third is included in the sets. More than 400 of these elliptical roofed thirds were taken into BR Eastern/North Eastern stock, with over a 100 being based outside the NE Area (mainly GCR, GER and GNoSR). The last of these only went in 1960. Often used as "Strengtheners" with the Gresley Non Vestibules in busy periods.
