There's a huge new redevelopment planned for the Earls Court area. More info here from the local authority, and a useful discussion here at Skyscraper City. So, is Lillie Bridge depot closing? And are there any upgrades or new works planned on the District in conjunction with this development? I'm thinking it might be an opportunity to build a grade-separated junction westbound to Olympia. More info here and here. It's also important to safeguard a 4-track alignment for the West London Line, e.g. for freight passing loops or additional platforms at West Brompton. Can anyone point me to plans showing the underground rail alignments and box?  |

The plans seem to show the Lillie Bridge depot area still reserved for TfL. I understand that there are already plans to reduce the conflicting moves caused by the Olympia service, so a flying junction would be an expensive white elephant. |

A better decision would be to grade-seperate the Wimbleware line. Currently it is only partially grade-seperated at the western junction.

I thought the Wimbledon line junction was grade-separated at the western end?

Very interesting, thanks.
I wonder if they considered routing the Putney lines into the Northern two roads at Earl's Court with flyovers and sending the Main lines into the southern roads, with the old Putney lines and required crossovers maintained as secondary routes. The Olympia service complicates things, but seeing as that's going away, perhaps a chance to simplify things?
Looking at the layout, It's almost like they intended this layout to ease passenger interchange and planned to finish up by adding grade separation to the east of Earl's Court to take the Putney lines over/under the mains to get to HSK....but with that in mind, I'd have thought that having both the Main/Putney lines on the centre or outer roads would have been better, as this means only a single flyover/dive under would be required to the east. Given the gradients, I'd have thought having the down main run into the southern road and the down Putney join the up on the flyover would have worked best, requiring just a simple flyover to take the up main over the Putney lines to HSK.

So is this part of the reason that Earls Court is such a bottleneck?
Could they rebuild the diveunder so that the eastbound line from West Kensington crossed beneath the eastbound line from West Brompton? And could this tie in the with work on the Earls Court redevelopment project?
If not, is there scope to remodel the junction at the east end, with the eastbound Victoria line dropping beneath the eastbound High St Kensington line?

I think the crossover from the EB Wimbledon line to the EB Olympia/Richmond/Ealing line should be brought back.

Very cryptic Dstock7080! Any more info on the plans?

There is a plan to re-instate the crossover from West Brompton to plat 1 and also HSK to plat 3 when they finally get around to resignal the line. It was taken out due to conflicts and the complex nature of the programme machines controlling these junctions. But dont look before 2020 for these to plans to come in

I went along to the last exhibition on the redevelopment and made the point to the organisers that the flyover needed to be built for Northbound from Wimbledon to the northernmost platforms at Earls Court. I suggested doing it by making West Brompton a Cross-platform interchange. (Make the northbound line run to the west of the WLL, then cross to the north of Earls Court) Main problem (apart from money) is that the redevelopment is not touching the "slab" that the current Earls Court exhibition centre sits on. ie. the new development will be built on the existing foundations. Thus, the redevlopment scheme doesn't make it any difference to building the flyover (or to the unlikely potential to 4 track the WLL) The report drawn up on the website www.myearlscourt.com/ does alude to my intervention in terms of "improvements to Earls Court". |

The WLL used to have a set of goods lines that ran on the western side. The Earl's Court slab is irrelevant to the four tracking, which would require a 3-4m or so strip of land along the western side of the WLL to be reserved.

Not true. The point here is safeguarding. If TfL has even an inkling that this route could be strategically important then it needs to set the boundaries to preserve options for the future. As freight increases then any slack will be welcome, e.g. for loops, or the holy grail of 4-tracking throughout. I like the suggestion from RBRJ over at Skyscraper City: |

Of course, sorry, I thought it was implied.
I'm not sure about the platforms though....West Brompton serves that purpose pretty well, and any platforms would be very, very close to it, and with a very long walk from the tube station.
