This has been discussed in a few threads here. There's a lot of issues that can cause this but much of it is caused by the number of splines and the kind of track. From experience, I have found that some track renders better than others and when the track is "heavy", it causes the other splines to take a long time to appear. On my very large route I've built over the years, I ended up replacing the pro-track I was using with regular spline track and found the rendering to be much quicker.

Hi! Thank you very much for your answer! The issue is very weird, as it only happens in just one bit of a tile. In the same tile, it works perfectly fine. I have seen what you said about he types of track, in this case any track causes the same issue, but why would it be in only a tiny bit of a square?
