It's still in its infancy and will still need to grow. What OpenGFX+ Trains offers you are
- a bulk wagon, a flatbed wagon, a covered piece goods wagon, a tank wagon and a refrigerated wagon with dedicated sprites for many cargos
- new livery override for the arctic TurboTrain, so that passenger and mail carriages match the engine
- Full support for ECS, FIRS and PBI industry sets
For the future we plan more specialized cargo support, including more loading stages and special treatment of more engines and trains and possibly adding a few selected additional engines in order to complement the set of available rolling stock over the range of years, especially for the early ones.
