The D15 is an Ebay win like most of my Engines. She has been fired up before some times but in excellent condition. I like it very much and steam it up quite often. It seems that I have a prefence for Engines with vertical cylinders. Tis ws built before 2007 because she has a lithographed base. The new ones have a black base.
The D15 is lot of fun and quite powerful. Easy to operate she to be destinated drive some unusual modells.
The Engine is surely capable to drive quite a handful of models. I will use her to drive Workman tin-models and / or a steam fair layout. The design seems to fit really well for that purpose .
