- Road Hog [road vehicles + trams, it's from the same author as Iron Horse and FIRS],
- U&Bridges [like in the name, rail/road bridges],
- U&RaTT [road/tram tracks with speed limits],
- U&ReMM2 [rail tracks with speed limits],
- Av9.8 Aircraft Set [planes, etc.],
- CHIPS Station Set 2.0 [very nice station set which has stations with waiting cargo animations]
If you want some updates for graphics in default OpenGFX, then I suggest adding:
- OpenGFX+ Landscape [removes grid from the map, modifies snow line, enables snow in temperate climate],
- OpenGFX Trees [like in the name, replaces trees and adds trees at the roadside in the cities],
- Stolen Trees [yes, they were stolen at some point, adds very nice trees to the game]
- HEQS [heavy equipment road vehicles, is also good road vehicle set, I'm not sure if it works with all FIRS' cargo].
