Found an archive of vintage Chicago Union Station pics, and included was this amazing locomotive that looks like something out of a retro science fiction story. I don't know how far back you folks are willing to go, but I'd love to drive something that looked like this.
Sadly, it will never come, at least from DTG. Since it was owned by the CB&Q, AKA the Burlington Route, which merged with other railroads to form the Burlington Northern, which merged with the Santa Fe to become modern day BNSF, so you can guess why DTG wont touch it.
Theres an issue with licensing where DTG can only sell BNSF branded content inside the US only. Outside the US, BNSF content has to be unbranded.
