They really won’t. As diesel becomes more expensive (and it will. It’s now over £1.50 a litre for cars and lorries right now with no signs of a price drop) then electrification or partial electrification and batteries will be the only way to provide a reasonably priced rail service.No it won’t, diesel trains will continue to operate on lines that are electrified no matter what that climate bandwagon would like to see happening. And if electrification (which can’t be afforded everywhere) isn’t complete by the time diesel units need to be retired - and if alternative fuel vehicles aren’t available by then - more diesel trains will be bought.

The transformer on 317338 is mega loud. If you stand in the door vestibule at the south end of the motor coach you can feel the buzzing through the floor.Some transformer buzzes can be quite loud on some electric trains.
Some 377s usually stable for a week or more in Horsham over Christmas and New Year. Lights on and buzzing away the whole time. I wonder how much it costs to run the air con for all that time.The things should be shut down while stabled. Leaving them on is typical railway waste.
The air con is maybe turned off during these periods.The transformer on 317338 is mega loud. If you stand in the door vestibule at the south end of the motor coach you can feel the buzzing through the floor.

Many years ago there used to be shore supplies at Paddington for the HSTs.
One of the reasons it was given up, I was told, was that a shunter was needed to connect and disconnect the cables and that it was too easy for the driver to take power while the rear power car was still connected...
I suppose more effective interlocks may be possible these days.
I'm sure I've seen fire engines have such a thing. The electric supply keeps the oil pump on and the oil hot to reduce wear on the engine. When they go out on a 'shout' they just drive out and the cable comes out and moves back to its default position slowly.Or just position the connector such that it will pull out without damage.

At some point, likely soon, the railway will be litigated against for noise and pollution nuisance. The 68s, without shore supply, have proved unsuitable for regular use in residential areas. The railway can't save itself money and inconvenience others without consequences.
But electricity is going up in price as well.
All rolling stock and railway operations have a statutory authority defence against proceedings for noise nuisance under section 122 of the Railway Act 1993. Premises such as station building don't. So you can't sue the railway for a noisy 68 but you could for a noisy station announcerIANAL but, who is going to bring the litigation, & against whom?
If it's on noise nuisance grounds, then fencing along the station boundary with acoustic fencing, & possibly changes to the loco exhausts, could be enough of a defence. The defence may also be able to have the affected properties checked to ensure that they met any planning conditions on soundproofing & windows. If they don't...
If it's pollution, then that's going to need a lot of resources for monitoring equipment placed all around the residences concerned to find out where the pollution is coming from.
If you then sue Chiltern, where does it get you? They have no power to get electrification done.
The defence would also point out the greater sources of pollution in the area, & could presumably ask why the litigant isn't taking similar actions over those.
Maybe the residents of Marylebone should take a greater interest in their MP.

Electricity prices have gone up because gas prices have gone up, & gas is pretty much the only fossil fuel used for electricity generation in the UK.* As more renewables are connected to the grid, the impact of gas prices on the electricity price gets reduced.
As an example, wind has been 39% of electricity generation so far today, with gas at 20%.
*There are now only 2 coal power stations left on mainland UK
And the other day wind was about 10% all day, low enough to bring some coal generation online. At some point I can see prices ending up changing daily ( which for domestic users who can change their usage a bit might not be the worst idea anyway ) if there's some sort of direct emissions tax. Until we really sort our supply, swapping everything to electric is somewhat just shoving the problem into someone else's backyard.Electricity prices have gone up because gas prices have gone up, & gas is pretty much the only fossil fuel used for electricity generation in the UK.* As more renewables are connected to the grid, the impact of gas prices on the electricity price gets reduced.

Electricity prices vary by the half hour. Traditionally only the larger industrial users have paid half hourly and they have the ability to vary demand to avoid paying the highest prices. The highest are usually around 1700 in Dec, Jan Feb.And the other day wind was about 10% all day, low enough to bring some coal generation online.

The shore lines on (most of) our ambulances auto eject.
There was guidance issued a fair while back encouraging us to use the auto eject rather than hand pulling the plug.
Maybe the railway doesn't want to have trains shoot power plugs across platforms when trains fire up though
If Vivarail's fast charge system proves to work, presumably that would be relatively simple to use for shore supply? The main difficulty will be working out a place on both train and track where the system can sit without getting in the way of some other piece of equipment like an AWS magnet of the TPWS grids. It would also make introducing battery-EMUs easier for when the electrification gets going in earnest (I can dream! lol).
Depends if you need 3 phase for any auxiliaries and also if the track circuits are immunised For return currentWould shore supply even need wires, a short length of third rail, activated only when a train is over it and a pickup shoe on the train would do the job.
Though if you sort the immunisation out for a shore supply, that's one job already sorted when you eventually do electrify.Depends if you need 3 phase for any auxiliaries and also if the track circuits are immunised For return current
Mains.What voltage are you talking about for Ambulances...
They'll have one final shout about all the Voyagers running under the wires today after a dozen or so Pendos got trapped in Wolves depot by a derailmentHopefully with COP26 over tomorrow the focus will go and it’ll all be put on the back burner again.

The Chiltern Mk3s use standard ETH so are supplied at 1000V AC or DC there are Static Converters on each carriage to covert to 415v 3 phase ACDepends if you need 3 phase for any auxiliaries and also if the track circuits are immunised For return current
I believe from what I've read in the past, that EMUs cost around a third less to operate than DMUs once the overhead wiring is in place.They really will and it does matter what is being said now to appease the tree huggers and the band wagon riders in Glasgow. The Treasury has effectively said “no more money” for large electrification projects so if the rail industry hasn’t found a viable alternative means of providing traction, more diesels will be procured simply because the only other choice (shutting parts of the network) will be even worse, politically and maybe even environmentally.
