Re: simcity - game bug
Hi @Mantakno - Unfortunately, this omission seems to have existed since launch. I found a few posts referencing it from 2013 and 2014, but not much after that. The sad thing is that SimCity is no longer being developed, so no more patches or fixes will ever be applied to the game. I'm sorry to say we're stuck with whatever problems are in the game, and this seems to be one of them.
I built a city in Huckleberry Island and Sawyer's Crossing just to see if it had ever been fixed. I was hoping maybe the visual is still broken, but the rail could still work. My cities haven't developed enough to plop the train station yet, but usually if there are tracks in the city you will see some trains go by to remind you to build a station. There haven't been any trains going by on my cities yet, so I think it's still broken.
You can certainly build a train station and tracks to use inside the city, but I can't even find a mod that enables you to fix the regional train track issue. I will reply back if I find a way to fix it, but at this point I think your best option is to delete the tracks from your city and use road transportation for regional needs. I wish I had better news for you. ☹️
