This can be achieved by following the procedure:
- Pause the game.
- Demolish a small section of the railway line that crosses the dirt road.
- Upgrade the road to desired level.
- Re-lay the railway line across the road, selecting the desired level crossing (if you have a choice*).
*You will have a choice of crossings if you have installed one, or more of the level crossing mods available on Train-Fever.net. (Highly recommended)
Hope this helps!
