The lifts and footbridge were installed at FH station as part of Network Rail's Access for All funding, which allows disabled passengers as well as parents with pushchairs to access the platforms without using the footbridge stairs.
However it didn't change the issue with wheelchair passengers being able to step on the train without the use of a ramp which LO are excellent in getting a member of staff to help with this. The platforms won't be changed either due to the fact that different type of trains are used on the Southern services, so we won't see a Canada Water situation where the train and platform are on the same level.
