I mean, the 211Ts are special. As I have repeated and will continue to repeat thill I’m blue in the face and have tapped a hole in my phone screen: they’re true prototypes. They are like the R110/R130/R131 program. You want to evaluate how the train behaves, how the people react to it, and to do that, you need to run them.
you run them every chance you get. If the brakes charge up, if the traction motors work, and if the darn thing is not on fire, send it out. You short handed and need to layup some trains? Lay someone else up, leave the Ts out there.
again, this isn’t just about the mechanics, but about the ridership. The people. How do they react to them. Do they use the gangways without a second thought. Do they like this idea?
