Class 31

The Class 31’s were among the earliest diesel locomotives on the UK network, making their debut in 1957. A small body size and lightweight design however made these engines incredibly popular, and even today they still see work on the mainline network.


Seen at Wansford is Sector Construction liveried Class 31, 31271 ‘Stratford 1840 – 2001’. The name comes from the Eastern Region locomotive shed in East London that was the home to many classes of both steam and diesel locomotives until its closure to make way for the London Olympic Village and High Speed One station.
