I dunno, Dave, maybe the whole problem is scale and the size of our stuff compared with theirs. For example, I see stories on layouts in MR where the guy has like 200 cars and maybe 20 locos that run on let’s say, a two-car garage-size layout. To duplicated this in large scale I’d need a warehouse or a very large yard (yes, I know there are large-scalers with lots of equipment).
The other problem with large scale is that it isn’t just a single scale, but rather several different scales sharing a common gauge. To put oneself in Walther’s shoes, if you were gonna taut large scale, which brand/loco/train set would you recommend to a beginner? When I jumped into LS in 1997 or so, we had lots of possible starter sets from LGB and in my case, from Bachmann. In fact, I bought a Colorado Southern freight and an identically named passenger set at $99 each from San Val. Of course, I soon needed more track, cars, locos, all Bachmann. I don’t know what USA Trains and the others were offering, but they probably had an equivalent. Nowadays, Bachmann’s starter sets seem to be 0n30, which as a scale/gauge, has siphoned off lots of enthusiasm and money from large scale. Truth be told, if I were to do it over, that’s where I’d be.
Finally, I’m guessing that Walther’s which is kinda a kissing cousin of Kalmbach and MR, knows the market, figuring that a dinky train set as described at the beginning of this thread, is all the company wants to expend any energy and money on (Sorry for the bad grammer. Don’t tell Sister).
