Very disappointing to see that the 9.22 Cardiff to Holyhead today is a 2 coach 150. Is that the best they can manage? They also have the 2 coach Northern 150 heading from Cardiff to Manchester this morning. Perhaps they are returning it to Northern?
That service has been booked a 158 for as long as I can remember. It's usually covered by a 150/175/0 if the 158 isn't available. This would be better off as a 3 car 197.
If the Northern 150 is heading to Manchester in service, it's unlikely going back to Northern as it will need to complete the full day. Apparently the Northern 150's are staying until Autumn.
