Must say, I do think the MK4’s are TFW’s best rolling stock from a passenger perspective (and the guards I chat to live working them compared to the units). Fingers crossed any HVAC reliability issues can be overcome. Whenever the wife and I go to Cardiff we always try to catch a MK4 set in both directions and go first class. As I’m TFW staff sometimes we go free, sometimes we pay (always offer and more than happy to pay the upgrade fee) but I do think the upgrade price is 100% worth it.
We travelled down from Shrewsbury on a 197 last Sunday and back on a MK4 on the Monday. Whilst I feel the 197 wasn’t as bad as people make it out, it certainly did seem worse than a 175 or 158 but better than a 150 or 153. MK4 still sits top of our favourites we tried the chocolate brownie mentioned above, and it was amazing, super gooey and not like a packer brownie even remotely.
I do hear rumours that TFW might want to replace the 67’s with a tri/bi-mode locomotive, possibly the class 93? Might increase reliability and reduce the running costs as those 67’s absolutely drink fuel. A guy from Chiltern told me that swapping from 67’s to 68’s dropped the fuel bill by a third.
If reliability goes up and running costs come down, surely that could only be a good thing for the longevity of the loco hauled TFW sets.
I did also hear they may want to try and get the Avanti 221’s when there’s available but I don’t see this to be as likely.
