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.

Heljan Sentinel Railcar – LNER Green/Cream – 2136 HOPE – 3180 – DCC Sound Fitted. Part number HJN1014‑DCC. The model represents a Sentinel railcar from the LNER era of the Big Four (LNER, LMS, GWR and SR).
The real Sentinel railcars, often called “Chip Vans”, entered service between 1925 and 1932. They were built to reduce operating costs and to attract passengers on local services, and are regarded as precursors to modern diesel railcars. At their peak the LNER owned 80 vehicles across 13 diagrams, with Diagram 96 and 97 being the most numerous. They operated on commuter routes around North London as well as rural branches in East Anglia, the Midlands, Cheshire, Scotland, Yorkshire and the North East. A 1934 LNER report recorded up to 2.25 million miles per year and 17 hours of daily operation, although lightweight construction and reliability problems led to withdrawal by 1948, leaving only No. 2136 “HOPE” to survive briefly into the British Rail era.
The Heljan model reproduces Diagram 96/97 railcars in the classic LNER green and cream livery, carrying the number 2136 “HOPE” and destination boards for Newcastle, Durham, York and Selby.
Key technical features include separately controlled LED lighting, ESU electronics with “Stay Alive” capacitors, a factory‑fitted speaker, a Next18 DCC decoder interface and an optional factory‑fitted ESU sound project. A low‑profile motor is hidden beneath the saloon, and the model is supplied with NEM couplers and magnetic coupler bars.
Standard equipment comprises five switchable DCC lighting functions, interior and cab lighting, bi‑colour LED head and tail lamps, detailed interior partitions with reversible seating, a detailed engine room and cab, and smooth, reliable motor performance. The model also offers variations such as Diagram 96 toplight vents, Diagram 97 droplight windows, a CLC variant and multiple regional LNER versions, each with appropriate destination boards.
