Tuffers was one of those stations that had a rather annoying lift/escalator characteristic.

The former is usually because there needs to be a mini concourse which
has access to both platforms, and it can't be any lower because the
tracks are in the way. I'll speculate that the latter is so that the
lift's machinery room can be at ground level.

Aye. That does make sense. But at stations such as the Claphams North & Common, at the bottom, platform end there is only one platform at the end of the escalator, and a flight of stairs to reach them. Angel may have had the same problem, as well as the other island platform Northern Line station, London Bridge. These last two were vastly rearranged, of course.
