Bug: chasing the train after turn on the switch of the antenna on the tower

[x1]

chasing the train with the parachute and reach the subway. stop in front of the gate to the subway and still have time left. But the gate is closed and the usual event doesnt start. message: signal of the train lost/ train left. It has to be a bug. The usual behavior I can check here (end last minutes of the video) https://www.youtube.com/watch?v=nBm73ZTHgDE) Is there a solution available? Experiences?
