Thanks, I did run across the Bachmann Peter Witt in STL livery. It's cool but not the one that ran on my route. It looks maybe a little larger than the Western Hobbycraft trolley - hard to tell - the WHC site doesn't have specs. There does seem to be a limited supply of all of this stuff so maybe I need to just get off being specific and take what's available.
Also - what's the general consensus on Superstreets for trolleys?
