Last night I was watching on YouTube about the GS engines. That is the poster was indicating issues with Lionel and these engines, speaking about design process. He briefly touched on the milk cars saying just look up on YouTube and you'll have a whole bunch of things come up.
In his talking about the design process, he said what a great portion of our community know very well. That was that there are some great engines from the TMCC into early legacy as far as great work horses that have no issues. I don't remember how many times I have seen one of our own suggesting to the original poster to look for these types of engines, or even some other like old KLine ones.
The poster also suggested what we have pretty much echoed here, go find older rolling stock. Today I put in my pre-order. It was just a few engines, that's it. No rolling stock at all. I told my local train store Tony, that there was no New Haven Cabooses, so I'd have to get an old one wherever he has them whether old Lionel or MTH. Since Tony has a great selection, I'm sure I'll be okay in that regard. I'll have to ask him as well if he has any Madison New Haven passenger cars as well, but I'm getting ahead of myself.
