So this afternoon I pulled this out, dusted off my note pad, and dug into starting a update on the session and the CMTMS soup. Its not easy, its kinda fun, but defiantly a pain in the bum. And In about 4-5 hours, got a product flow cart of sorts made up, the first 10 recs done, and about half a dozen cars set up and working so far.
What I can say is that with my flow cart, it will make making records a bit easier, but switching 10X harder. I might even have more cars in the yards at session start up, and get away with having fewer cars on the ECS tracks. This saves ECS records seeing as CMTMS3 cant handle more the 99 ECS records.
So yea.....that a thing now....
