Wonder if Menards has toyed with idea of an engine?
My guess of a short answer would be no.
First, which operating mode? Conventional with E reverser, or get a TMCC licensing for engine, or have MTH build a PS3 engine?
Second of course, would be, what to build? Do a classic E or F "bulldog" or modern diesel? Steamer (what wheel arrangement)?
Third, What road name has most appeal, current or fallen flag(s)? Pennsylvania or BNSF, Rock Island or Union Pacific?
I notice that Menards carries Lionel starter sets so might not be difficult to get Lionel to do a Menards engine, maybe a simple Lionel Chief type engine, which of course leads right back to third topic of road name.
In conclusion, never mind, too much hassle I imagine. But would be fun to speculate, none the less.
