Tees Valley line can't get through the first tutorial "Class 37". After starting the loco and driving for a bit the instructions are to manage the throttle and brake to stay under the speed limit. However there is a red signal ahead and no matter how long you wait it never changes to green. Requesting from the controller does nothing it remains red. Proceeding forward will halt the scenario as a fail due to signal passed at danger
I could not find any issues in the Class 37 introduction. You probably just forgot to set the switches (press 9) in front of you, a total of 5 switches must be set to complete the introduction.
I have a similar problem. It just asks you to manage speed and brakes and then you turn into a red signal. There was no instruction to set any switches in the introduction. But I will check if I can do this.
