As has been mentioned elsewhere on this forum very recently, if a DMU Sleeper train were to be built, it would be possible to locate the engines under the seated coaches only, and leave the sleeper coaches as trailer vehicles: For example, the "Nightstar" rakes were to be available in two different half-train formations; the first consisting of two seated coaches, a lounge car and five sleeping cars, and the second of three seated coaches, a lounge car and three sleeping cars: Put a 750hp engine underneath each of the non-sleeper carriages and you have 2250hp for eight carriages in consist 1, and 3000hp for a seven carriage rake in consist 2. Of course an EMU Sleeper train, as could be used on the London to Glasgow/Edinburgh service, would have no such underfloor engine noise issues and could rival the existing mark 3 carriages for quietness even with motors under the sleeper coaches.That or someone will have to refurb/make a multiple unit as a sleeper set... with engines under the floors it'll be noisy as hell :cry:
I seriously doubt that a new build of loco hauled coaching stock will be forthcoming in the future:
The HSTs have been assessed as capable of continuing in front line service until 2035 if required: I don't believe that many will remain in service that long, even in the present difficult financial climate. The GWRs' "Dean Goods" 0-6-0 locos were considered exceptional for remaining in service for up to 75 years as main line locos, and they were freight engines: Intercity passenger trains should not be expected to remain in service for a period of time as long as 60 years. I can imagine that the mark 3 sleeper rakes could continue in service until this time though, outsurviving the HSTs.
The next Great Western franchise will be a prime opportunity for the purchase of new diesel trains for the South West routes, operating primarily via the Berks and Hants: With Paddington to Cardiff electrified, those services will utilise electric IEP trains, and the Bristol to Devon & Cornwall traffic could be catered for by Crosscountry and Cardiff to Plymouth/Penzance services, making the London to Exeter, Plymouth and Penzance services suitable for the likes of 9 carriage Meridians. If such trains were to be delivered in 2020, then they would be due a mid-life refurbishment in around 2035, when thoughts could be turned to electrifying the Berks and Hants route to the South West and allowing cascading of those trains elsewhere, which is when replacement of the mark 3 operate Sleeper trains with electric replacements would have to be considered.
The Scottish parliament could probably be prevailed upon to extend their OHLE projects to encompass Aberdeen, which seems highly logical: This could coincide with a new build of EMUs in the mid-2020s to replace both the 225s and the HSTs used on the Aberdeen runs, giving a common fleet operating both sets of services, leaving only the future of the Inverness trains to be decided as concerns the operation of long distance ECML HST services.
As for the MML, who knows: Electrification could be on the cards following completion of the north west and GWML schemes, which would see the HSTs displaced, if not, then it would be fairly simple for EMT to replace it's remaining HSTs with a small additional number of Meridians.
