Class 37/4 Refurbished 37430 'Cwmbran' BR Blue (La

The Iconic Class 37

The British Rail 1955 Modernisation Plan paved the way for the wide-scale replacement of steam traction with diesel locomotives, and one of the most successful diesel locomotive types to emerge as a result of this was the English Electric Type 3

Between 1960 and 1965, English Electric's Vulcan Foundry produced 309 examples of these 1,700hp Type 3 diesel-electric locomotives. They were designed by Robert Stephenson & Hawthorns at the request of British Railways.

When TOPS was implemented the type was designated Class 37.

The Class 37 diesel shunters were so popular with railwaymen that in 1985, a major refurbishment program was authorized to extend the operational lives of 135 locomotives.

The nose-end communication doors were sealed, and the four-character head codes were plated over during the renovations.

To increase the tractive effort, some freight locomotives were equipped with lower gears, while others were fitted with extra ballast or even more powerful engines.

A new subclass was created for electric train heating (ETH) refurbished locomotives, allowing them to operate on passenger trains all year.

Following restoration, the diesel engines were repainted into a wide range of liveries and returned to service in the early-1980s, following the regionalisation of British Rail.

Passenger locomotives appeared in BR Blue Large Logo, InterCity and Regional Railways schemes whilst freight engines received varieties of Railfreight livery, Transrail, Mainline and Loadhaul.

The Class continued to be widely used into the Privatisation era, with examples operating for the likes of EWS, DRS, West Coast Railways and Colas.

Some refurbished examples have received ‘retro’ heritage repaints.

Bachmann's Class 37/4 Refurbished 37430 Cwmbran in BR Blue

One of the first of the stunning all-new Bachmann Branchline class 37's to be announced in 2022 was Class 37/4 No. 37430 ‘Cwmbran’ in BR Blue Large Logo livery.

The British Rail Class 37 is a classic among fans and modellers, and the completely re-designed model replica returns to the Bachmann Branchline series in 2022.

Following the footsteps of the award-winning Bachmann Branchline Class 47, their all-new OO scale Class 37 was developed from the rails up to ensure that this classic engine is modelled more precisely than ever before, and it also has the same excellent characteristics as Bachman's Class 47.

Our new 37 is brought to life with an exquisite livery application using true-to-prototype colours, typefaces and logos, thanks to the use of high fidelity mouldings, many separately fitted parts, and extensive tooling choices to capture the specifics of the real locomotives throughout their lifetimes.

Along with an unprecedented array of lighting features, a Dual Fitted speaker system is fitted to all models – bringing this sound-fitted model to life.

For the ultimate experience, upgrade to a SOUND FITTED DELUXE model with a motorised radiator fan and authentic tinted windscreen glazing.
