Congratulations on your 20th anniversary of your "SuperTrainz" project! I did remember watching your Trainz videos back in 2006/2007 (middle school) which was years before I myself became a furry/aeromorph (I drew anthro machines for 10 years now) and if it weren't for you, I would've never heard of NBC's SuperTrain (& its catchy disco theme song) and your own Amtrak creations. So keep up the good work!
Also, I used your track for a module (now on DLS) I made a while back for anyone who may be interested in using it for projects relating to the cancelled "Breitspurbahn" from WWII. I think the SuperTrain might've got some inspiration from that old plan, especially with the wide German trains having stuff like rolling luxury hotels.
I didn't know about the failed German train until recently, Saw the video online somewhere not that long ago, Yea, I wonder if NBC / Universal knew about that ? Possibly not... Granted the actual show's creators might have, too bad we can't ask them, are they still even around to ask ? Might be something I should make, kinda right up my alley, so to speak ... ;-)
