Okay, so, I just typed my reply to your message, accidentally edited it and deleted it, so now I'm typing it again. Of all the engines on Sodor, right now I choose to be Salty.
Anyway, I just realized my normal TOMY Thomas is actually the first model of TrackMaster Thomas instead. Silly me. Either way, it has a bit of a laggy start after turning on, as well as TOMY Henry. Most if not all of my other trains do this, but it's almost unnoticable. They pick up speed eventually anyway, and I think it makes them more realistic. Also, aside from that, and Mavis, all of my Plarail/TrackMaster/TOMY things are working perfectly.
EDIT 1/15/2016: I lied about only Mavis being broken. The scared (O-face) Thomas is broken too.
