As the Jet engine is a bit long in the tooth the good news is that Epic has announced that its Unreal Development Kit (UDK) is available for download for absolutely nothing. This kit was used to create games such as Gears of War and BioShock.
The bad news is that if the product makes over $5K, then a quarter of the profits go to Epic. This is in addition to the fact that a serious rewrite would be necessary before UDK could power Trainz.

Still, maybe an option?
