Looking very smart in its freshly applied coat of National Coal Board blue paint, Class 10 shunter D4067 Margaret Ethel - Thomas Alfred Naylor stands outside Rothley carriage shed on 3 September 2022, on static display during the Great Central Railway's Autumn Diesel Running Weekend. The open bodyside doors give a glimpse of what makes this loco different to the more ubiquitous Class 08 shunter. Instead of an English Electric engine, this class is fitted with the Lister Blackstone ER6T engine.
