Is there any technical reason why there are no Greenbrier (formely Gunderson) articulated double-stack cars in RW, like the Maxi-Stack I or Maxi-Stack IV?
Trainz has them and unless there is something that eludes me, I don't see a reason for not having them available in RW3/4.
I had already set up a Maxi-Stack I in Gmax for Trainz (now redundant on my PC) and I think I'll finish it for RW.
