Baldwin '794'

4-6-0 Pannier Tank Locomotive

Help Restore 794!

We need all donations - however small. Please be generous.

794 is a 4-6-0T locomotive of the Baldwin class 10-12-D. It was built for the Great War, one of a large number of similar machines. After the War, it was sold and exported to India, where it worked on a sugar plantation, carrying the name 'Tiger'.

It was imported from India in about 1985. Now owned by The Imperial War Museum, this loco has a complete rolling chassis but the boiler is in poor condition. Now transferred to Porthmadog, it is intended that a new boiler be fitted and the that loco will operate under the pseudonym 590, being almost identical to the original WHR locomotive of that number. The expensive new boiler will require substantial donations from members of the public.

Please contribute to the Peter Thomason "590" Memorial Fund and help rebuild Baldwin 794 as a replica of 590.
