Manufacturer description

The Class 25 Diesel Locomotive has long been a fixture of the Bachmann Branchline OO scale range, but this all-new model owes nothing to its predecessors. Designed from the rails up, this new family Class 25s from Bachmann Branchline encompasses Class 25/1s, 25/2s and 25/3s, capturing the differences – some small, some anything but – between the three distinct types. Regardless of the particular locomotive being depicted, every model features high fidelity mouldings and numerous separately fitted parts, with the utmost attention to detail paid to the features of the prototype.

Our new Class 25 is brought to life with an exquisite livery application using true-to-prototype colours, fonts and logos. Following the precedent set by the Bachmann Branchline Class 47, and subsequently the 37 and 31 too, the Class 25 features a full lighting suite and is available in three formats; standard, SOUND FITTED or SOUND FITTED DELUXE as in the case of the example – this award winning specification features our motorised radiator fan system and authentic tinted windscreen!

CLASS 25 HISTORY

Following publication of the British Railways Modernization Plan in 1955, the British Rail Class 25 diesels were introduced into service in 1961 and were more powerful than the Class 24 Bo-Bo diesels introduced three years earlier.  A total of 325 Class 25 Diesel Locomotives over several sub-types were built, most at BR Derby, but some were constructed at Crewe and Darlington with a further 26 built by Beyer Peacock of Manchester. 

As Type 2 locomotives, the Class 25s were often seen working in pairs to increase operational power.  The class was, however, a true mixed traffic locomotive, equally at home on either passenger or mixed freight duties.  They were well suited to the task of replacing steam traction on duties over a wide area of the British Railways system and were allocated to numerous depots across the Eastern, London Midland, Scottish and Western Regions.  Although not allocated to the Southern Region, they were often seen on incoming and through traffic from the other regions.  Following closure of numerous lines in the late 1960s and the resultant loss of passenger work, during the 70s & 80s they were more likely to be seen on either freight, newspaper, parcels or specialized duties. with notable examples including the provision of train heating for steam hauled specials in their swansong years.  The Class was finally withdrawn from service in 1987, but twenty preserved locomotives survive to the present day.

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

Bachmann's latest addition to their OO scale range is a Class 25 diesel locomotive, modelled as BR Blue (Small Yellow Panels) locomotive D7660. This model is part of the Branchline range and features a high level of detail and accuracy.

The model is available in two formats: standard and sound fitted deluxe. The sound fitted deluxe version comes with a Zimo MS450P22 DCC sound decoder, a motorised radiator fan, and tinted windscreen glazing. The locomotive's lighting suite includes directional lights, illuminated headcode panels, and cab lighting, which can be controlled separately.

The model features a five-pole, twin shaft motor with two flywheels, providing smooth running and realistic haulage capabilities. The diecast metal chassis block and bogie towers add weight and stability to the model. The bogies are constructed from multiple components and feature full relief detail.

The model's detailing includes separately applied metal parts, such as grab handles, windscreen wipers, and etched radiator grilles. The cab interior is also detailed, with a control desk, seats, and ancillary equipment.

The locomotive is designed to operate on curves of second radius (438mm) or greater and features a Plux22 DCC decoder interface. The sound files are produced specifically for the Bachmann Branchline Class 25 and use recordings from real locomotives.

The model is available in a pristine BR Blue livery and features authentic liveries applied to all models, including logos, numerals, and text. The model's sound specification includes numerous functions, including directional lights, sound on/off, brake, single horn, two-tone horn, and more.

The Class 25 diesel locomotive has a rich history, with over 325 locomotives built between 1961 and 1966. They were used for both passenger and freight duties and were often seen working in pairs to increase operational power. The class was finally withdrawn from service in 1987, but 20 preserved locomotives still exist today.
