It all stems from the last contract ATW were awarded, which failed to consider the amount of growth in passengers over the period. Since then TfW have been playing catch up. They also retired the old Pacers as they were not DDA compliant.

It's not even as simple as borrowing some units from other TOCs. Across the UK there is a shortage of actual carriages.
Can the Pacers be attached to the back of modern units? ie, the train is DDA compliabt but not all carriages are.

It did strike me when TfL were making a lot of noise about getting rid of the 'hated' Pacers. I'd rather four of them on a busy service than two modern carriages.
