Mine actually runs just fine, and I really like it - bought when they hadn't been out for ALL that long, but maybe it's not one of the very first batch.... it's a little odd, with two small Mabuchi motors each driving one axle, but it runs smoothly and reliably and the sound (Dietz) is lovely.
A bit basic on the detailing, especially inside, but then that's TL45 for you.
Oh, nearly forgot, I've also got a very Germanic-looking Steam Railcar, an old LGB conversion from a small batch built for GRS sometime last Century... now retrofitted with Massoth DCC and sound.

PS: Duncan, sorry for temporarily derailing (pun intended) your thread with all this railbus deviation....
