If it were possible, I feel that bringing in flatcars loaded with Abrams and such would be really cool. I'm sure licensing with military would be a big hurdle as well as the fact that could be a lot of modelwork for something like a tank. But it would be super 'Murican to haul armor.
TSC had a military flatcar pack, so it isn't impossible, but unsure how people outside the US would react to such content.
This can work and remember there have to be two versions of it one with SD40-2 GP38-2 SD70ACE. Since the US military has bases in Germany you can actually use S type freight car M1 Abrams with DR Baureihe 132 DB Baureihe 232 DB BR185.2 & 182 behind them would have been a Zacns tanker goods wagon
An interesting smaller route project might be one of the military railways. In the UK the long closed Longmoor Military Railway probably the best known example. For the US there is an extensive network at Fort Eustis. However the subject matter brings with it a whole host of political and security issues so unlikely to ever happen.
