To check if there is an issue with the path place a train on the track and get in it. Then open the map and hold CTRL over the track. This should show a highlighted path if the train can get ...

If you click on either of the locomotives, you'll notice that the next stop is highlighted red, and if you hover over it it says "no stops with this name exist". It looks like either you renamed a train stop, or you moved/replaced it (resulting in a new randomly-generated name).
