LGB and the “what scale is it” inquiries end up on a myriad of other frustrating topics. Here’s my estimate as to the “why” LGB has no defined guide for themselves as to a specific scale:
My take is LGB builds specific trains to the largest sizes LGB’s staff thinks the public will think is OK on their “G” gauge track. I think LGB knows the key word in large scale is “LARGE” not the word “scale.”
Years ago, my conversation with Lewis Polk centered on his encouraging 1:29 to be the industry’s large scale guide for size. His interpretation was 1:29 was the largest size that was most visually acceptable by most people who wanted trains larger than “O”. He may have been accurate. MTH’s 1:32 works for the larger locomotives - both diesels and steam. Testimony to that is the Challenger and Big Boy from MTH. In 1:32, those locos are BIG. As to the other rolling stock, 1:32 appears small compared to what “large” scale is (was?) to most consumers. Yet, coming in late in the game, MTH appears to be garnering a following – especially with the BIG locos.
Me? If I had started in 1:32 and built my garden RR accordingly, I would be staying with that specific scale. No, instead, I have mix of Bachman, LGB, and a USA diesel. The rolling stock is also a mish-mash. Meanwhile I can always look at an array of 1:1 scale boxcars on a siding and see some tall and some short. That helps.
Sigh…
