Journey by Journey / Thames Valley Branches / Re: A trip on GWR's Battery Electric Train - 17/12/2024

I agree with most of what you say, TonyK. There is a danger that decision makers will latch on to these compromise solutions - discontinuous electrification and fast-charging battery trains - as though they were ideals rather than stop-gaps.
The fast chargers are interesting though. The battery packs take a 14kW supply, which I believe is similar to a household connection, so you can put one anywhere there is space for a couple of storage boxes.
I agree entirely about the peril of stop-gaps, made far worse by the tendency of the price of the ideal solution going up and up in between procrastinations. My own battery charger is a 7 kW job. That is a pretty normal option, being able to deliver the charge at household voltage with a 30A current. 14 kW would need a 60A current, doable with a 3-phase supply. I would assume the battery charger would take that. I didn't realise it was only a 14 kW supply, given that high speed DC▸ chargers for cars can run at 150 kW. Given the information in grahame's report of his trip, 14 kW would be enough to keep the West Ealing to Greenford service running, but without capacity for much more. But would much more be needed? Your comments on the weight of batteries etc are interesting. Double the weight of a diesel engine and fuel, but how much does that matter? Each 3-car Class 166 set weighs about 115 tonnes empty (per Copilot, to be checked at a rail weigh station), plus another 25-27 tonnes of passenger when fully laden and being charitable. 5 extra tonnes on 140 tonnes isn't likely to affect range and performance unduly or pose any problems for the network - unless I have also missed something blindingly obvious.

As I recall, the HSTs▸ were introduced as a quick stop-gap when it became obvious that the planned electrification wouldn't be done before the previous kit had to be replaced. So they were introduced, and electrification was forgotten about. The IETs▸ intended to replace them years after they were supposed to have been retired were originally supposed to have been all electric between Bristol, South Wales and Oxford, but were fitted with diesel engines as a quick stop-gap when it became obvious that the planned electrification wouldn't be completed. My guess at what will happen to intercity services next will be some other hasty stop-gap once they get too close to reaching 40 of their planned 25 years in service.
But it isn't just intercity services. Someone, somewhere is going to have to make big decisions very soon about what happens to commuter trains too. The choice seems to be between implementing plans already made to electrify much more railway and buy new electric stock, or do practically nothing and enter a new period of managed decline in railways. Battery trains will do an excellent job filling in on track that isn't worth electrifying fully, as the trial at Greenford seems to be showing. But there aren't any more around, nor any more fast charging points, so they will need either their own infrastructure or at least some 25 kV OHLE to power and charge along the routes.
Broadgage is right, we can't go on with diesel forever. It's already an anachronism, given that there is no engineering reason why the whole rail network cannot be run on electricity alone.

This is getting serious. Anyone growing frustrated with Go-op's 12-years-and-counting campaign for new trains will be pleased to know that they are also getting frustrated with GWR▸ 's service. At least according to this in The i Paper Frustrated commuters are taking on a £650m rail giant to run trains for themselvesFed up of being neglected by GWR's timetable the West Country residents behind Go-op plan to offer their communities a better rail service Alex Laurie and John Hassell of Go-op, at Westbury Station in Wiltshire, where their services should soon offer an alternative to GWR (Photo: Abbie Trayler-Smith) Moaning about Britain’s railways has become a national pastime. But rather than joining the chorus, frustrated rail users in the West Country are taking matters into their own hands – by launching their own train company. “You find yourself standing on windswept platforms thinking ‘I could do better than this’,” says Alex Lawrie. He’s the chair of the community owned Go-op, which last month was given the green light to compete with the giant multi-national owned Great Western Railway (GWR) in Somerset and Wiltshire. It’s a story that might remind some of The Titfield Thunderbolt – the famous Ealing Comedy film about a group of villagers running their own railway line. But Go-op is a much more serious business. Next week will see another important milestone for the co-operative rail venture – currently owned by 280 members – as it seeks to attract the capital it will need to realise its plan to get its own trains on the tracks next year. The story continues at source for subscribers, or at the MSN copy of the link for interested cheapskates (like me). The word "soon" is not defined in terms relating to our progress through the heavens.

Don't panic - MPs▸ have now been informed of the issue. From the BBC» : Christmas train travel could be hit by staff shortages
Lord Hendy said that the transport department was going to "keep a close watch on staffing" throughout the holidays.
I still speak some Civil Service. "Keep a close watch" means the same as "ignore". Not that there are likely to be many in at the DfT» to do the ignoring. I can't help wondering when I see tiffs between the DfT and a private TOC▸ and then passing the blame to each other how excuses will be given out when the "whole thing" is in, supposedly, one set of hands
Exactly. If it isn't sabotage, it's the government. The whole blame apportionment industry will have to be dismantled.

At long last! Trains will be driven, managed and cleaned by civil servants again, which should guarantee a reliable service around the clock on every day bar 25 December.
Being serious, though, this should simplify negotiations with unions at least slightly, as there will eventually be one employer to deal with, although it's going to be a few years before full implementation. There will presumably be cuts to back-office numbers as services such as HR▸ , payroll, and uniform design are amalgamated. I don't suppose we'll notice much difference for quite a while.

Interesting hypothesis given her caving in to ASLEF» with a "no strings" pay award that made no progress on Sunday working.
No option but to make a “no strings”. All TOCs▸ are on different T&C’s! Should have been left as each individual TOC negotiated its own pay deals. At least the crazy notion of the railways being privatised is coming to a rapid end, along with the façade of independence from government. It should be all back in public hands within not much more than a decade. There will be serious negotiations with the unions they get the best of each TOC's T&Cs for everyone across the board, after which the government of the day can start talking about weekend working.

No, my advice to anyone sane is to forget about being a MP▸ . Stick to something where you are universally adored, like presenting TV cookery competitions.
I seem to remember that didn't work out very well for MP and celebrity food writer Clement Freud... I man I admired hugely, despite his dalliance with Parliament, until his reputation was posthumously wrecked. His association with the late Captain Sir Tom Moore may have saved him, until recent events, but I shall always remember his programme involving a dinner in a Viennese restaurant. He took out his wallet and said how lovely it was to visit a country where they put a picture of your grandfather on the banknotes for you. And another gentleman (?) currently in the news.
Another day, another defenestration.

Guilty as charged
At least somebody has put their hands up. All of this hoo-ha vindicates my view that being a politician is not a very good idea, and should be left to someone else to deal with. Yes, it all sounds very nice from the outside, with cheap beer, a decent salary, expenses-paid trips to exotic locations with your voluptuous diary secretary, and a pension at the top of the generosity scale, but you are detested not only by all the people who didn't vote for you, but by half of your own colleagues in parliament as well. You can forget all those laws your government made about protecting your privacy or rehabilitation of offenders, they don't apply to you. You're fair game with no closed season. It isn't just the big crimes that will get you splashed across the front pages - one small fart in a lift, and the CCTV▸ will be top of the 10 o'clock news. No, my advice to anyone sane is to forget about being a MP▸ . Stick to something where you are universally adored, like presenting TV cookery competitions.
