The Class 158 is one of British Rail’s most successful second generation Diesel Multiple Units (DMUs); first introduced in 1989, all but one of the original units remain in traffic to this day. This all-new Graham Farish model follows in the footsteps of the brand’s award winning Class 319 Electric Multiple Unit and captures this iconic prototype to a tee.

The pinnacle of N scale second generation DMUs, the Graham Farish Class 158 combines high fidelity bodyshells with an underframe that’s adorned with separate components depicting the engines, electrical equipment, and auxiliary gear. It’s the livery application which really brings these models to life and every element has been replicated in miniature. Whilst the main colours are spray painted, the myriad smaller logos, symbols and lettering are applied using a specialist printing process, using BR and corporate specification fonts, logos and colours.

Driven by the low-level drive mechanism, each vehicle sports uninterrupted views of the interior which is fitted out with tables, chairs and even metal luggage racks – made visible thanks to the saloon lighting. The inter-vehicle coupling system ensure that the two vehicles work together in harmony and enables the use of a single decoder for DCC operation. This SOUND FITTED model comes pre-fitted with a DCC sound decoder, providing realistic sound effects when used on both analogue control and DCC straight out of the box.

CLASS 158 DMU HISTORY

The British Rail Class 158 Express Sprinter is a Diesel Multiple Unit (DMU), built specifically for British Rail's Provincial Services sector between 1989 and 1992 by British Rail Engineering Limited (BREL) at Derby Litchurch Lane Works and outshopped in Regional Railways Provincial livery. They were built to replace many locomotive-hauled passenger trains, thereby reducing cost of operation, and to allow cascading of existing Sprinter units to replace elderly 'heritage' DMUs. The majority of the 182-strong fleet of Class 158 units were built as two-car sets, with 17 three-car units constructed specifically for use on Trans-Pennine services. Similar three-car units were built for use by Network SouthEast but these were converted to Class 159 specification before introduced into service, with toilet retention tanks and other modifications to operate over the third-rail network.

All but one of the Class 158s remain in service today (2023), with operators including ScotRail, Northern, Great Western (GWR), East Midlands Trains (now EMR), and Transport for Wales (formerly Arriva). Former operators include Central Trains. The Class has worked extensively across the UK network, even into East Anglia as far as Stansted Airport and Norwich. Some 158s have been converted to additional Class 159s and now operate for South Western alongside their original classmates.
