No thought here of those of us who use East Croydon as a hub to all points south. Southern have declared an intention to cut all services from FH & Syd - terminating any remaining at West Croydon. That forces an extra connection at Norwood Junction which makes Gatwick Airport, Brighton et al inacessible for the infirm as there is no step free access at NJ and the narrow steep steps make it very dangerous if you are carry luggage or are not very fit.
Yep the LO is a mixed blessing though no doubt it will become even more popular when we get the Crossrail interchange at Whitechapel (hopefully also reducing the squeeze on the Jubillee down escalator at Canada Water).
Six car trains would be good to spread the load out even if only 4 can be used at some stations. Does anybody know the new platform length at Whitechapel which I predict will become the major LO interchange.
