Prototype Era
Era 3 (1923 to 1947) The Big Four (LNER, LMS, GWR and SR)
These charismatic vehicles – nicknamed “Chip Vans” due to their bright livery and smoky chimneys – were introduced in 1925–1932 to reduce operating costs and attract passengers to local services. They were a precursor to modern diesel railcars.
In some ways, the LNER’s Sentinel railcars were victims of their own success, attracting so many passengers that they often couldn’t cope with demand.
At their peak, 80 vehicles across 13 diagrams were operated by the LNER, with Diagram 96 and 97 the most numerous. They worked across all LNER areas, from North London commuter lines to rural branch lines in East Anglia, the Midlands, Cheshire and Scotland. Yorkshire and the North East were key strongholds.
A 1934 LNER report showed they outperformed early diesel railcars, covering up to 2.25 million miles per year with some working 17 hours a day. However, lightweight construction and reliability issues led to withdrawal by 1948, with just No. 2136 HOPE briefly surviving into the BR era.
Our new model celebrates these important but often overlooked pioneers, offering Diagram 96 and 97 railcars in classic LNER liveries—perfect for both branch lines and main line layouts.

The Heljan Sentinel Railcar – CLC Buff/Brown – 602 (manufacturer part number HJN1010) is a 00‑scale model of a Sentinel railcar that operated for the LNER during the era of the Big Four railway companies.
The original railcars, often called “Chip Vans” because of their bright liveries and chimney smoke, were introduced between 1925 and 1932 to reduce operating costs and to attract passengers on local services. At their peak the LNER ran 80 vehicles across 13 diagrams, with Diagrams 96 and 97 being the most numerous, serving routes from North London commuter lines to rural branches in East Anglia, the Midlands, Cheshire, Scotland, Yorkshire and the North East. A 1934 LNER report recorded mileage of up to 2.25 million miles per year and daily operating periods of around 17 hours, although lightweight construction and reliability problems led to withdrawal by 1948, with only one unit surviving briefly into the British Rail era.
The model represents Diagram 97, number 602, in a Cheshire Lines Committee light/dark brown livery and includes destination boards for Stockport, Liverpool, Widnes and Marple. It is fitted with a Next18 DCC decoder, ESU “Stay Alive” capacitors, a factory‑fitted speaker and optional ESU sound project, as well as separately controlled LED lighting functions and a low‑profile motor concealed beneath the saloon.
Standard equipment comprises five switchable lighting functions, interior and cab illumination, bi‑colour LED head and tail lamps, detailed interior partitions with reversible seating, a detailed engine room and cab, NEM couplers with magnetic coupler bars, and smooth, reliable motor performance. The model is offered with both Diagram 96 toplight vents and Diagram 97 droplight windows, and is supplied in several LNER regional liveries.
