The British Rail Class 08 is a class of diesel locomotive designed for shunting. It was the standard BR diesel-electric shunter, based on the LMS 12033 series (later TOPS Class 11). Production started in 1953 and when it finished in 1962, the class had become the most numerous of all British classes, numbering 1193 in total. A few remain in service today.

Overview

The locomotives were built at the BR Works of Crewe, Darlington, Derby and Doncaster.

The Class became sub-class 08/0, when locomotives from the class were given cut-down cabs for use on the Cwm Mawr Line, and became Class 08/9.

The engine is an English Electric (EE) 6 cylinder, 4-stroke, 6KT. Traction motors are 2 x EE 506 motors with double reduction gear drive. The main generator is an EE 801.

Design variations

There were variations on the basic design, which were given the following TOPS design codes:

CLASS 08/9

Class 08/9 locomotives were modified from the standard class by being given headlights and cut-down cabs in which the overall height was reduced to 11’ 10” (3.61 m), for use on the Cwm Mawr line.

In fiction

In the Thomas the Tank Engine and Friends TV Series originated by the Rev. W. Awdry, there are a few diesels that are the same class. They are Devious Diesel, 'Arry the Iron Works Diesel, Bert the Iron Works Diesel, and Splatter and Dodge.
