That diagram is being used to balance units to get things back to normal today.The MK4's return to normal today however I see there is something that has become very very rare these days on the Cardiff-Manchester route is covering one of the diagrams. A 158!

Real-time train running information for 1W59 1254 departure from Cardiff Central to Manchester Piccadilly on 31/12/2025. From Realtime Trains, an independent source of train running info for Great Britain.www.realtimetrains.co.uk
The 158 will be an unusual visitor to Manchester but will swap out at Shrewsbury to get it back to its usual routes.
A 197 then covers Shrewsbury-Cardiff-Crewe where a Mk4 is planned to swap in this afternoon to cover the remainder of the diagram and balance for tomorrow. Only 1 Mk4 was kept at Canton over Christmas and the engineering works hence the imbalance this morning.
