That's my understanding too. But with the contact wire being so low under the station bridge, I do expect that clearances from the platform to the pantograph will be an issue. (Especially as 810s appear to have conducting rather than insulating pantograph horns.) Maybe they can get a...

Presumably this is just an accommodation bridge to connect the land on each side of the railway. And since that land now belongs to National Grid or NR, who also built a separate access road, there is no legal requirement to reinstate the bridge.

I wouldn't be surprised, but those are 1000HP diesel engines. Range extenders for 100mph BEMUs would only need to be a tenth of that size. I think it's a fair assumption that the wires will get all the way to Sheffield - eventually. Despite the rotten economics, which only deliver a financial...

I understand the LEVC TX electric only range is 78 miles. With the extender, the combined range goes up to 333 miles. That sounds a bargain to me. That 200kg to give you 250 miles of extra range will weigh much less than the batteries that gave you the first 78 miles on electric only. By all...

Sure. And a battery EMU with a diesel range extender only needs a tiny diesel engine (about the size and weight used in a family car), as it can run at full power for the whole time that the train is away from the wires.

The Chinese sometimes transport new viaduct sections along the viaduct itself. As shown in this video: But I've not seen any suggestion that this would be done on HS2.

A single 345 can carry 1500 passengers, including standing. A full 400m HS2 train will only ever carry 1100 pax, and they will only arrive one at a time, with at least 3 minutes before the next one turns up. So the Elizabeth Line will be able to cope perfectly well if every other train starts...

Do we know how are the sections will be transported to where they will be used? They seem too large to go by road.

It seems the norm on the MML now, also. I wonder how many times in the past 50 years the OHLE has been brought down by a truck hitting one of the masts? EDIT: See for instance on the vehicle access track here...

Thank you. It looked very different somehow, but I couldn't put my finger on it. I since realised that in the picture above, the I-beam is oriented so that the flat base of the "I" is parallel to the track. On the the MML, the I-beams are oriented with the base perpendicular to the track, as...

Is that the same OHLE series as they are using on the MML?

It's quite possible. Given the relative ease of access to EL platforms, I'd expect OOC to be the preferred interchange point for all long-distance GWML passengers arriving in London who are heading into Central London. Which is most of them. The only passengers staying on board will be those who...

Those timings seem a bit slow. ...

Do you know how far? My assumption is they will have cut it back to the shortest possible stump consistent with not interfering with the live lines in the future.

Are there any videos which show construction progress to the north of Delta junction? I'd be intrigued to see how much, if any, of the junction towards the Eastern Arm is going to get built - or even evidence of passive provision for it to be added later. To help locate it, the junction is...
