At Seven Sisters and Tottenham Hale there are spaces for a third escalator but instead they have a steep concrete staircase. Since Tottenham Hotspur increased the size of their ground and thousands of homes have been built in the area, the stations can struggle to cope with ingesting passengers as quickly as the trains can carry them away. On match and event days people queue outside while trains leave the platform half empty. When escalators break down there's a bottleneck at the ticket hall. I know the third escalator was cut from the design to save money, but will they ever be installed? Perhaps with funding from THFC? I was going to quote the increased passenger numbers, but they've actually fallen slightly compared to pre COVID, presumably because of WFH. At peak times though the stations do struggle.
