Hi all, I know that 150 workings aren't that rare, since I occasionally see one coupled to a 158, and I've managed to catch one a few times too. However, I was walking home yesterday on a path alongside the WCML at Tipton station, and I was passed by a singular ATW 150 working, presumably to Birmingham International. How rare would this working be? I'm guessing it's standing in for a 2-car 158 working, but wouldn't the 75mph top speed limit it slightly, especially when it comes to the paths along the WCML?
