Random question...passing through CJ platform 17 earlier with time to kill and decided to see how much spare platform was available for when Southern move to 8 car services on the WLL.
...well. In a previous discussion I seem to recall suggesting 8 cars should be easy...and I couldn't have been more wrong! From a base of the existing 4 car service, moving the signal and trap points south buys a car's length on the existing platform that gets you to 5, and at a generous push you might squeeze on another car's worth on the northern end...and that's about it.
So does anyone know what Southern have planned? 2 cars of SDO seems a tad optimistic.
You might squeeze some more platform on the south end, but it seems to me to be a great opportunity to sort out the northern end. It means demolishing some station wall and moving the subway entrance, but behind them it's just greenery and an access road that can be bridged over, enabling them to straighten out the platform and get it to 8 cars easily. You would then be able to straighten out 16 as well as shutting 17 for the bulk of the expansion is perhaps feasible, as you can just slew the lines over as you adjust the platforms. Brief sketch.
