I tried it with a steam train didn’t work and when I did it with a electric train it went to the last station then said no path when the was clearly a path and there were no one way signals stopping it from going in a Serbian direction it normaly only happens for me round about 1930 but until then all the lines work but after that I can’t assign new trains or trains in deports to line cause the line just disappears and I’ve tried removing the stations and adding them back on the line and it don’t work so, any help now ?
