They were built by the [[Yorkshire Engine Company]] in [[1960]] (first ten, D2850-D2859) and [[1961]] (D2860-D2869). They were built for use in places of restricted [[loading gauge]] and curves such as docks. They had the door to the cab at the rear, with a railed [[veranda]] behind the cab. This feature was very unusual on British Rail locomotives. It was used on many Yorkshire Engine Co. designs and was/is quite normal in [[North America]]n practice. {{British Rail Locomotives}
