Our most popular steam locos are based on the infamous Tinkerbell design by Roger Marsh, as an attempt to build the smallest loco where the driver sits in the loco rather than on a tender behind the loco. The original was built in 1968 and is still in service today at the Moors Valley Railway in Dorset. Many examples have been built over the years, and the DMR is proud to run two of these machines.
Princess was built in 1989 by Edgerton/Horsfield to Roger Marsh's popular design, and was immediately put into service on Brookside Miniature Railway. She came to the DMR in 1999 with our other locos, and has been in regular service ever since. She received a new boiler in 2004 and has been in regular service ever since.
Lady Pauline was constructed in 1982 by Alwyn Kay, a local model engineer, again to Roger Marsh's popular design. She was also used extensively on the
Jack is our youngest steam locomotive, being completed in 2001. She is a 5" scale model of an 18-inch gauge locomotive built by Hunslet in 1897 for Mount Pleasant clay works. Jack was joined by Gwen in 1920, and was withdrawn in 1958. The prototype is preserved at the Leeds Industrial Museum.
The model was based at Millerbeck in Cumbria from new until October 2006 when it was moved to DMR. Though it has the power to handle a full train, due to the gradients on the line it has a tendency to lose grip, so only runs with two carriages.
