Talking of short formed EMR services, the Crewe route seems to have lost the luxury of 3 carriage 170s since the route extension and timetable changes. Now seems to be 2 carriage 158s or 156s again. Any reason for this?
They were used on the Crewe route because the traincrew who worked on that route mostly signed them. They've been moved elsewhere for now as traction knowledge is a bit more widespread. They will be back I'm sure.
