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  The Class was finally withdrawn from service in 1987, but twenty preserved locomotives survive to the present day.
