I'm not sure if anyone has noticed, but when I passed through HOP station last Wednesday, it was being 'deep cleaned' by several cleaners with cloths and spray cleaner attacking all the paintwork. I'd be interested to hear whether anyone has noticed the difference.

The slippage behind platform 1 is clearly serious and, at the very least, the wall at the back of the platform will need to be demolished and rebuilt. I'd say that more major works will be needed to stop the movement, possibly including replacing the sheet metal piling that has been put there at some time in the past, presumably to stop exactly the sort of movement we are now seeing. Whether the problems are due to the works next door, or to the removal of the trees, is an interesting point and one, no doubt, that Network Rail's engineers will be arguing with Southwark's contractors.

For what it's worth,the metal uprights at the rear of the platform do not support the canopy. That is supported on central pillars. They are there to support the fence at the rear of the platform. However, it looks to me as though movement of the rear fence supports could distort the canopy roof. I wouldn't be surprised if removal of the fence and its supports happens pretty soon to avoid any damage to the canopy.

I'm prepared to bet that the problem won't be sorted for the launch of the East London Line on May 23 and I wouldn't be surprised if it's not sorted by the end of the year.
