One AI company's train make the other's blocked

You can see two railway routes in the picture below. Blue one is an intercity passenger line with only 1 train and no signals. The other is a yellow coal route with 2 trains and signals. And you can see a blue station on the yellow railway tunnel, and just above the entrance. So, the yellow coal train on the upper right corner cannot move.

Where is mine? The red tramway is mine.

It's a known bug in TTD. Whenever a station or a depot is placed directly above a tunnel entrance (with the track point in the same direction, just as in your screenshot), and a train occupies the block before the station or depot, the block of the other track with the tunnel are also marked occupied.

[EDIT] As for your own tracks, you can avoid building such a constellation, but in this case you would have to take control of one of the AI companies to rearrange the track layout.
