Considering the amount of money that has been invested into the 67's, with hindsight they would have been better off with the original plan of 5 car 197s on all Manchester services. As
@Topological quite correctly pointed out this would have also been more convenient for both passengers and operationally at Cardiff with no need to split every 2 hours. Even though a good percentage of passengers do not travel either side of Cardiff it is surprising sometimes on the services that still run through from West Wales to Manchester just how many people do make journeys from Swansea etc to stations on the Marches and also to Crewe to change for other routes from there.
I realise the plan was changed because the 170s were no longer staying rather than the need for something better to operate the Manchesters. Personally i find the 197s perfectly fine for long distance travel and the comfort is more than adequate in my opinion. And if every service was 5 cars as booked then most of the time there should be plenty of seats Its a shame we are now stuck with the under performing MK4's even if the service is excellent when they run.
Does anyone know what the plans are for the MK4's over the weekend? Looks like we had 197018 on 1W11 this morning but nothing showing for 1W61. All others seem to be MK4's as it stands at the moment.
