Sampled this service today and it is a nice little runner. The line speed is very slow, but what little acceleration was allowed with those constraints, was good. It would be nice to see how it would perform at a higher speed.

Thank you for such excellent 'on the ground news report from our correspondent at the scene', Oxonhutch. Wink Cheesy Grin

William Huskisson MP (Member of Parliament, or Mile Post (a method of measuring the railway in miles and chains from a starting point - usually London), depending on context) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: Stop, Look, Listen.

Yeah, maximum linespeed is 40mph which you might just about reach down the hill between Castle Bar Park and South Greenford.

That’s why these 60mph units are a good fit for the branches.  None of the Thames valley ones are above 50mph and none of the Cornish branches go above 55mph.

Perhaps it’ll be a new unit design rather than this old D stock, but such speeds and distances are (mostly) suitable for battery trains using this technology.

This begs a question- what happens to these units when GWR (Great Western Railway)'s management contract ends later this year?

I think we've been told that GWR/First Group actually own these trains. Are they obliged to hand them over to the temporary DfT» (Department for Transport - about) body running the network pending GBR (Great British Railways) finally being formed and taken over? Does this experiment simply come to an end leaving First/GWR to dispose of them as best they can?

FirstGroup will effectively become a ROSCO» (ROlling Stock COmpany - about) for these units, looking for takers like the DfT» (Department for Transport - about). At the right price, I suspect they'll be let...

To me, it makes sense to prioritise wherever possible, using this technology on urban/suburban lines where the emissions issue is more acute than in rural areas.  This is not to say that rural areas should be excluded though. Ideally the technology allows for rapid roll out for both.

This is making me reflect on the capabilities of the kit used by Ember's long distance coach network in Scotland, and also January's experience using the Carmarthen-Aberystwyth link, albeit that was an electric bus rather than an electric coach. This then makes me wonder what the nearest equivalent to these is in terms of rail passenger vehicles.

I thought the idea of this train was as a test bed for the technology. I hope there will be more battery units, but not adapted D stock.

The answer to that question will be who the funders were / are.  Just because the First Group are stated as the owners does not mean they own it outright.

Problems with the battery train on the Greenford branch today.

Two round trips were cancelled before it was replaced by a Turbo (Class 165 and 166 trains used on Thames Valley services).
