Y'all are such creative discussers, LOL! I will say though, the trains have been getting their much needed TLC, last I recall and heard... No telling which is next though. Either way, I'm ALL for supporting new trains and whatnot, but unless Disney decided to play secret, we all know for sure that those trains would be posted etc etc etc. I know I'd made jokes about it, but it's just what it is...
IF there's new trains in the works, and Disney DOES want to play secret secret, you still have to consider purchase options, design options, length of build time, which then feeds what they're doing to the current fleet now...
If new trains are to be a thing (and I'm not saying they are or aren't (though I wish they were)), there's a fair amount of work to go into getting those new trains, which means they're sprucing up the current fleet to handle the next few years... That's of course, if it's a thing... I know some things, but don't quote me on THIS information.
Back to what I said though, if there's new trains, my opinion is an updated version of the paint scheme!!
