Has anyone else noticed that there are no 48' spined husky stack car sets from ANY of the manufacturers? All 48' stack cars are individual units (which I have many) instead of the AB 5 car units of the real world. The high wall stack cars from MTH and Atlas are spined and the 53' Gunderson maxi-IV cars from Atlas are also spined (albeit they are 3 car (ACB) only).
I was thinking it would be nice if I could convert 48' husky stack cars of the same Road # to 5 car spine units, but I doubt if this endeavor would be practical. I do have some vague recollection of someone on the forum attempting to do this but I'm not sure of the outcome or if I remember incorrectly.
