Hell, in Narrow Gauge NA protoype they were few.
D&RGW had the switcher, the US Army tested a road helper unit there, SPNG had the “Little Giant”, WP&Y had the shovel-noses and such.
But by and large we are the confines of steam.
Be it outline or live.
That said, I have dismals.
LONG before I was in #1 gauge.
I just recently parted with my Adams and Sons FT’s.
I have many others, All-Nation F-3’s, SW’s, General Models 600HP switcher, Kemtron Geep, and that’s just the 2-rail.
I have probably more than that in 3-rail.
Hell, 2343’s don’t need no stinkin’ sound systems.
You can not only HEAR them coming, you can feel it in the benchwork.
I used to have one here on the CCRy.
But, alas, it was drafted.
