Is the location at about 00:24:30 destined to be a feederr station?
After Cross gates toward Garforth the video shows a number of OLE posts. I had understood there were plans for future 4 track here, yet the posts appear "too close" to the other existing line to allow for this?Another great cabride update from Ben Elias on YouTube.
You can see the same for Leeds - Crossgates as well. But it's interesting (ok... not that interesting) to look at the detail:After Cross gates toward Garforth the video shows a number of OLE posts. I had understood there were plans for future 4 track here, yet the posts appear "too close" to the other existing line to allow for this?
I'm no expert in OLE design but along that stretch it appears they need to have a mast on that left hand side every so often. If it were to be four-tracked in the future, those masts would be removed, or possibly there would be enough space between the two pairs of two tracks for the mast to remain in place. (In a two-track layout the tracks are separated by a 'six foot', but in a four-track layout the two pairs of tracks are separated by a wider 'ten foot').What about at 1:18:22 where there seems no space for 4 tracking in future (unless it is a trick or the camera perspective)?
Individual OLE masts aren't all that expensive in the grand scheme of things, particularly if you're going to have to be out adding electrification for the new masts in the future anyway. If there's a couple of places where passive provision is fiddly then it makes more sense to just do something that works now and deal with replacing some masts later if the 4 tracking ever happens.What about at 1:18:22 where there seems no space for 4 tracking in future (unless it is a trick or the camera perspective)?
I concur. Kings X Remodelling was one where a temporary OLE structure was installed during temporary track layouts being in play; once the final layout was in place, said structure was removed.Individual OLE masts aren't all that expensive in the grand scheme of things, particularly if you're going to have to be out adding electrification for the new masts in the future anyway.

Honestly you can spend too much time trying to anticipate every eventuality. At some point it just slows everything down and makes it more expensive. In gardening terms it's like putting up a fence post now because you need a fence, even though you hope that in a few years you'll have the money to buy next door and have a bigger garden.Oh yes I can see that, just seems like it would be less time/effort/hassle to have them in the right place from the get go... Otherwise it's more weekend closures and cost to decommission and remove them before you even get started..?
A bit like planting a tree in your garden despite knowing you plan to reconfigure the lawn next year...
Agreed. See https://www.railforums.co.uk/thread...lectrification-news-and-updates.236007/page-7Honestly you can spend too much time trying to anticipate every eventuality.

Agreed also. AbsolutelyAgreed. See https://www.railforums.co.uk/thread...lectrification-news-and-updates.236007/page-7
I'm very glad the TransPennine Upgrade is happening and just hope they keep the momentum up until it is done in full.
At a guess, temporary supports to stop the arm from swinging around before the wires are attached.what do the yellow things do?
I’d concur with thatAt a guess, temporary supports to stop the arm from swinging around before the wires are attached.
I love this photo. It shows a stovepipe type arm from the portal right close up in the foreground. .Photos from east Garforth of the electrification progress
Ben Elias' videos are invaluable for us as designers sometimes. He is doing the lord's work.Another great cabride update from Ben Elias on YouTube.
I note from the latest Robert Stenhouse picture on Flickr that Ravensthorpe Leeds direction Platform 1 has been removed.

Was the loop from platform 3 15mph before? That will feel massively different! A class 331 there will feel very different to any sprinters before.Summary of latest line speed improvements:
Micklefield junction
Increase from 80 to 90mph on route to and from Church Fenton.
Church Fenton
Northbound, increase from 80 to 90mph around curve south of the station.
Southbound, 125mph extended from River Wharfe viaduct to Church Fenton North junction, then 85mph through station and around curve - up from 70mph through the curve.
Loop from platform 3, 50mph round curve and joining mainline towards Leeds.
Speeds from latest Sectional Appendix.
