Not a major glitch, only visual one.
I built two diagonal railroads right next to each other and noticed the trains overlap each other in a weird way.
At some point the right train renders above the left train which is wrong z-order.
Here is video demonstration (sorry for bad quality):
And static screenshot:

Thanks for the report however I do not believe we will be doing anything about this. Train rendering is fragile at best given the 2D nature of the rendering engine.
If you want to get ahold of me I'm almost always on Discord.
