As you may know, Northern Trans Pennine has its own set of passengers. My Suggestion now is to bring these Passengers to other routes but with gray hair. Firstly, that would mean more variety in passengers, and secondly, you now have senior citizens as well as adults. Maybe you could halve the walking speed of these seniors to make it a bit more realistic. This idea came to me today when I was taking a ride in the Class 101.
