Here's a great video by a real train driver filmed by him, with explanations of the route taken this year. With unedited passage through tunnels and yes Totley Tunnel. The only time he stops the video is waiting time at stations. Things to watch for include the speed signs, especially into Sheffield. Plus how quickly the train accelerators. When he stops the train in a station, the driver has to know when to apply the brakes. There's nothing telling him now stop for the next station.
