Is there much of a difference in the running costs between the Streetlites and the E400s?
I've always found it strange that they run deckers on the X21 at night. From my experience there's definitely not enough passengers to warrant a double decker!
We'll find out the true answer to that once we start running the E400s.
The difficulty with the X21 is that it's a cross-town service. There's no where you can stop running a double-deck and start running a single-deck, both efficiently and without causing disruption to customers' journeys with a changeover.
With other services like the 60, they terminate in Park Lane Interchange, so you can quite easily have another vehicle step in on an evening.
