Got a small shipment of detail parts today from Wiseman, and decided to go ahead and use them now...
I added a Pyle generator to the trench engine, between the stack and the forward sand dome.
I also added a coal shovel on the fireman side and an oiling can on the engineer side.
As an afterthought, I decided to build a shop table. Eventually, it will be inside and enclosure that will also include coal and ash bins.
