I wrote multiple comments on here in past years about the hazardous situation that used to prevail at Slough station exit on the quite narrow Down Main platform, once the exit gateline was put in actually on the platform, which used to be beyond acceptability in the morning peak if relief line services, plus the Windsor shuttle, all arrived at the same time, and the crush to exit spilled out well over the yellow line, whereupon a Down Main service came on the scene at 125mph. On a couple of mornings a revenue block was even in progress, with BTP in attendance, it must have been particularly concerning for drivers, many of whom gave a considerable horn on approach.
There was an "excuse" that because the station building is a Listed Building (it's a Brunel original) it couldn't be varied. In recent times common sense has arrived.
