Apparently the train had partly left the platform so opening the doors was not an option until the TOp had herded the passengers from the cars already in the tunnel. In this situation the station staff are meant to operate the “butterflies” which open one set of double doors on each car but as there were no staff on the platform at the time and HOP has lifts rather than escalators they had to come to down the spiral staircase and the Central Line is about 200ft below ground.
I did hear that there were only three station staff which I find a bit surprising, it was around 7pm on Sunday evening, HOP is one down the line from NHG and it gets very busy on Carnival weekend so I’d have thought they’d have put some extras on. LUL always ask for volunteers to work that weekend but I have been told that a lot of staff will do it once and then don’t want to do it again. A CSA told me that this year at QUE they got a lot of abuse because neither of the lifts were working and the Super got assaulted on Sunday because the last train had gone. I only ever worked on Carnival weekend once when I was on stations and while it was busy it was quite a jolly time so I guess I was lucky.
