So out of 22 vehicles, only 5 are not allocated work today - meaning they're either in a rake of spare coaches, or undergoing maintenance. Of the 17 vehicles that are out in service they're spread far and wide in 14 different sets. Hope that gives an insight into how rakes are regular changed to allow for maintenance?
