I was getting the error "Train warp track is blocked at the destination" when warping a horizontal train. I did some troubleshooting and thankfully I think I found the source. I only get this error if there is a military target within 2 tiles of any part of the train's destination, even if they aren't actually blocking any part of the train. Gun Turrets, Laser Turrets, Flamethrower Turrets, Tesla Turrets, and Radars near the train will cause this error. I'm not sure if this is intended, but it did cause some headaches trying to figure out. If it is intended, I'd ask that error message be changed to indicate that the train can't warp near turrets, or add that info to the Tips and Tricks entry.
