Good morning everyone, I happen to see ghost trains in traffic, or rather you can hear the sound and see the lights, if I go external with the 2 and 3 button the train can be seen, locoswap does not report any errors, all the dots are green
It's a long standing problem which as far as I know hasn't been fixed but running the 64-bit version rather than the 32-bit one may help.. Try moving the camera around a little, that may bring the ghost train into full view.
There was (occasionally still is) a problem with trains only displaying their couplings in the 3D world. You can see them on the 2D map and hear them in the 3D world, but only see their couplings. Sadly, I forget what the fix is.
