I like a lot the Union Pacific Big Boy but the number are Front the Front part it mean to have the same number of the main part and same for the tender for example UP 4019 in front the main part of the steam locomotive and the tender and not 4019 the main part of locomotive, 4018 the front part of it and the tender 3952. With this I mean they can fix it please, it's a nice dlc but the number are the problem.
there is coming a new big boy by smokebox and btw wrong place to post this right place https://forums.dovetailgames.com/forums/technical-reports.37/
You don't have to, but Smokebox's Big Boy is going to be much much better than the old RSC one, with lots of new features and much more realism. But yes, I'd recommend buying the new one.
You can always change the old one for the new one in scenarios using Ts-Tools or even the in-game editor. Official scenarios you may have to clone to do this.
the if you really hate to put in whatever number you want to put on the locomotive then don't use the old one and still use the new one I get what you are talking about and yes it is a pain but you can play with the Smokebox version and there will be a difference in seeing which one is which
Smokebox has said there isn't any set in stone release date. So my guess is that it'll come out when it's ready to come out. I do recommend keeping up with Smokebox's Facebook and YouTube pages for updates on the development of the new Big Boy DLC though.
Smokebox has said that it will be released in the spring but no official date, but just like steammaster4449 said to keep up with Smokebox's news on the Big Boy and its progress
