What is British Rail Class 97?
[[British Rail]] reserved the [[TOPS]] '''Class 97''' designation for departmental [[locomotive]]s. These were used for special or engineering duties. They were therefore of several different classes, lumped together for numbering purposes. Some locomotives were converted from redundant engines, whilst others were purpose built. In 2008, [[Network Rail]] once again used Class 97 for signalling test locomotives (Class 97/3). {{British Rail Locomotives}} {{transport-stub}} [[Category:British Rail locomotives]]
