what is it?

The British Rail Class 69 is a class of diesel locomotives which are converted from Class 56 locomotives. The conversion work is performed by Progress Rail at their workshop in Longport. The Class 69 was developed to fulfil the needs of the rail freight operator GB Railfreight (GBRf), which was unable to purchase additional Class 66 diesel locomotives yet sought more capacity in a similar performance band.
