Donald 'Duck' Dunn in The Blues Brothers said, "If the 5h!t fits, wear it."

He also said he was in a band, "powerful enough to turn goat p!55 into gasoline."

There's your answer. Get a blues band together, throw in a few micturating ungulates and you've got a ready source of fuel. Job's a good 'un.

An update on the IPEMU ... (I think we have several threads ...)

Battery-powered trains possible for WalesThe UK Government is not guaranteeing that it will give Wales a promised £125 million contribution for electrifying the Valley Lines, if alternative technology is chosen.

Indeed, a Welsh government transport official has confirmed that it is looking at cheaper alternatives to electrification — including battery-powered trains. These have already been trialled in parts of the UK as replacements for costly (and heavy) diesel trains.

Called independently powered electric multiple units (IPEMUs), the trains are powered by lithium iron magnesium phosphate batteries

The costs and timescales of railway electrification have risen dramatically since 2014, when David Cameron made the pledge, and this has led the Welsh Government to “take soundings” from rail experts in Europe and Asia onalternatives for the Valley Lines (potentially including new technology such as battery-powered rolling stock): and while a UK Government civil servant said earlier this month that the Department for Transport had not yet decided if the £125 million “would still be available” if an alternative to electrification were chosen, the Welsh Government said it should not be penalised for exploiting technological developments.

Simon Jones, the Welsh Government’s transport director, said: “We might end up with some kind of hybrid solution that involves battery-powered trains, for example. When Mr Cameron made his pledge in 2014, I guess it was envisaged that we would be putting in pylons for the entire length of the Valley Lines.

We may not need to do that because of the way that technology has moved on, but we shouldn’t be penalised for finding a different technological approach to delivering the same outcome.”

I'm a follower of Noel Dolphin of Furrer+Frey (who make OLE kit for NR) and he seems to have been spending lots of time in Cardiff, spends lots of time talking about their recharging stations, and the other day was on the new VivaRail mock up of the old London Underground D stock which has had batteries fitted.

I'd joked a while ago that if VivaRail agreed to them being converted in Wales, then the Assembly might have them as a cheap source of new stock for the Valleys, but perhaps I wasn't too far off the mark? A few lengths of switchable 3rd and 4th rail in strategic locations should be enough to charge the things, and regenerative braking should mean that they can top themselves up on the way down the hill.

Sorted.

Conductor rail charging at stations is certainly possible, I suspect that the conductor rail would have to be dead normally and only rendered live when a train was over it.
Unless the conductor rail was at a less dangerous voltage such as 110 volt DC.
Despite the vast currents involved 110 volt should be doable with the transformer and rectifier mounted close to the track.
Or light duty and simple overhead within the station. Both the overhead and the pantograph could be much cheaper and much simplified if only used when stopped rather than at speed.
