CIÉ 201 Class

The Córas Iompair Éireann 201 Class was a class of 34 diesel electric locomotives manufactured by Metropolitan-Vickers at their Dukinfield Works in Manchester. They were a smaller, lighter and less powerful version of the 001 Class and were originally intended for branch line passenger and freight (mixed traffic) duties. They were introduced in 1956 and, although their duties changed over the years, were in regular service on the Irish railway network until the mid-1980s. Six were sold to Northern Ireland Railways (NIR) in 1986.
