Hi all, firstly this is not a question about interchanging MK3 and MK4 carriages.
The TOC's are retiring their HST's and 91/MK4 fleets soon. I'm aware GWR and Scot-rail are refurbishing HST's (been on one already - loved it) and TFW are getting some Mk4's and driving vans.
Based on rising demand for frequency and capacity nationally, as an interim solution pending the next generation of trains coming into existence, questions are:
1. How many short sets could be economically produced from the existing stock, taking into account age and corrosion etc?
2. What routes could they and should they run on?
3. What diesel locos are out there that could haul the Mk4 stock on the non-electrified network?
