Hi, On SEHS (among other routes), sometimes if I stand up (particularly on the 395 but also the 66) while the train is moving I'll be ejected from the cab, pressed against the roof of a tunnel, and then drop to the ground unable to move once the train has passed. It's almost as if the train has no roof. What on earth is causing this, and is there a way to stop it (other than staying sitting down) please? Thank you
