These should be electrified there is no need for dedicated battery stock.
With the possible exception of Marlow (because only 1 train per hour off-peak) I agree, but clearly somebody at Network Rail doesn't because the TDNS has Marlow and Henley (at least) as battery operation recommended.
- Cornish Branches (DCBMU) - 5 diagrams
Possibly but would the Cornish mainline be electrified by then? Should it not be a common pool of BeMUs not a dedicated ones for the branches?
Exeter to Penzance is down as "Ancillary Electrification" but presumably the recommendation is that it needs to be completed in order to deliver a 'net-zero railway' in the most cost-effective way. I suppose logically Exeter-Penzance locals would come from the same pool as the Cornish branch stock. Also my anaylsis of diagrams assumes Falmouth would remain as a shuttle to Truro - the 'Cornwall Metro' proposal to run those through to Newquay would rule out units that lack OLE compatibility.
- Wrexham Central - Bidston (DCBMU) - 4 diagrams
This will be part of MerseyRail by then with 3rd rail electrification to at least Upton.
- Conwy Valley line (DCBMU) - 1 or 2 diagrams
Whatever TfW are running on the coast
The North Wales Coast Line is recommended for electrification in full (core electrification,
not ancillary). Merseyrail are only fitting a subset of their new fleet with batteries for their Headbolt Lane extension, so even if it was the same basic class of unit as used on the coast it would still be a dedicated subfleet for the Conwy Valley.
- Bittern Line, Wherry Lines and Ipswich-Lowestoft (HFCMU) - 15 diagrams
Same as above they have already got the Stadlers, bit of extra electrification plus battery power pack instead of diesel.
Well, Network Rail has them down as hydrogen and (unlike the Welsh routes where hydrogen is recommended) very little of those Anglian routes would be under the wires. I agree though, it seems likely the Stadlers would be used if possible given that they're already in place (just a question of whether the diesel engines can be replaced by some form of hydrogen power) which is why I had them listed under 'plus maybe'.
To summarise however, you have gone through my list of routes where a unit with no OLE capability could be used and, in most cases, identified reasons why they wouldn't/shouldn't. Therefore, you have reduced the number of Civity DMUs which could potentially be used from a maximum of just under 50 to pretty much zero.
I honestly can't see any objective measure in which the 195s are worse than 142s.
A 195 is an improvement over a 142 in terms of capacity, and possibly air conditioning. In some other respects, the 195s are just as bad as 142s, but I can't think of any where they are worse than a 142, apart perhaps from being heavier and the fact that the 195s are newer and therefore we're stuck with them for longer.
Maybe in 25 years they'll be rebuilt to run on battery power/hydrogen/nuclear fusion anyway.
My point is that, to get a full 35 year life out of them without failing to implement Network Rail's recommended decarbonisation strategy, they will need to be substantially rebuilt to facilitate the use of OHLE. They are, as the topic title states, 'not a step forward' - they are standing still at a time when massive change is needed.
Big improvement on what they replaced. I can't help feeling they'd have been better with an end gangway for multiple working though.
I think that rather depends on what they actually replaced and on what duties. Yes it is the Pacers that have been withdrawn, but are the 195s actually working the routes the Pacers were on or have they been used to cascade Sprinters around? I agree with you on the unit end gangways though.
