A very common allocation is the E400s on the E's on Weekends, There used to raise capacity ( Especially during the Summer Holidays ) when not required on the X34
Not all of the allocation is used on the E's on Sunday though, Normally comprises of 1 to 3 E400s with the rest being made up of Branded E300s and non branded E200s.
