Some new-ish tracks appeared to be placed on top of the old tracks of the old sidings in Rayners Lane. What are these for? Is it just temporary storage for track replacement work (elsewhere) next weekend?
Overnight remedial works have already taken place on 11/12 points on Rayners Lane Jct, clear evidence of packing in new ballast (or new frogs can't remember) to eliminate the kick that Westbound Metropolitan services used to get when traversing the junction.
The diamond crossing is being done too this weekend. Then 13AB renewed and converted to Surelock in September.
Been a few weeks since I last walked the area but a lot of work has clearly taken place on resleeperimg 11 & 12 points recently yes. The new sleepers are plastic, I assume from Sicut but not sure if they are the only supplier LU use or not. Plenty of fresh ballast around the sleepers which is easily visible from a passing train both EB and WB. The improvement in the lack of vertical movement in the track when trains were passing over was also very noticeable when trackside. The movement was most noticeable with Met trains coming across the Junction generally. At the time I walked it there hadn't been any replacement of the frogs or any of the switch rails etc.
The kick that Piccadilly trains got off of the check rail on 12 points was very obvious even when trackside, didn't notice this when down there last time but not sure if this has got any 'better' with the recent works or not!
This is the only video I could find that shows the "kick", this video dates from 2015 so it hadn't gotten that bad yet. At 7:14 watch the connection between the two front cars as this shows the lurch best. From the Westbound platform you used to clearly see the leading car lurch as it crossed the diamond, unfortunately I couldn't find a video of that. The Piccadilly lurch at 2:20 is less obvious from the filming but if you watch the space between the cars you can see the lurch just before it passes out of view.
