If the gates have time restrictions at Forest Hill for off peak, this will have problems for people trying to give themselves lots of time to get over the bridge especially if not young and sprightly, with afore and oft mentioned pushchairs, shopping and suitcases.
I will this afternoon be travelling back from LB to Sydenham with a heavily laden buggy, baby and a rucksack so this should be interesting especially as I have to walk around and catch the train back up to FH. Last week the gate opened ok however only after pushing the button for several minutes as the staff were clearly busy.
