train says: "no path" on a track with no signals

[yuvalyly]

I builded a track from my coal mine to the main base and the train keep on saying "no path" until I manually move it to a specific spot or more, I tried to separate the track from my oil line (I cutted the line from itself but it doesn't matter because I'm testing it on the stop at the base.) and remove all signals but it keeps happening. please help.

Post a save file, screenshot does not tell too much

-- edit:
Oh, there is no reason for save file. There is a rail signal that blocks your expected train travel direction. It is near head of locomotive, little to East
