Took another ride on the new Elizabeth Line - this time with a view from the cab. And whilst I did, I spoke to Keith Valla - a Driver Team Manager with MTR - to ask everything you wanted to know from a drivers perspective. How does the signaling work? Where do the drivers book on? Why are there dwell times at some stations? Do trains really reverse themselves in the Westbourne Park sidings, and loads more.
