(at least three).
Only after you do that, head towards the partially opened gate with a railway car crushed under it.
Get under the gate door.
This means that you will have to toss the barrel to the neighboring ledge twice.
Spots where to do that have been shown in the above screenshots.
After you reach the upper level, head towards the tracks.
Return to the chamber behind the partially opened gate.
The car should stop in the spot shown in the above screenshot.
Climb onto it and jump towards the neighboring ledge that used to be inaccessible.
Turn left here and reach the handle.
Start pulling on it, which will initiate the gate.
Do not release the handle, until Trico reaches here.
Head towards the dark tunnel again.
Call on Trico, mount him and command him to enter the tunnel.
