Also in one of the Leicester University buildings. I seem to remember signs changing from 'do not overtravel', to 'overtravel is not dangerous' if you chose to ignore the former...

Wasn't it something like "travel through the loft and the sump is not dangerous, but not recommended"? I remember there being a sump involved.

Either way, i never went round either end of that lift. But i still got stuck in it once, when it broke down. Now i regret not having overtravelled.

Also in Birmingham University Library I recollect from some decades ago. Not the sign though.

I'm sure there was one in the Aston Webb building too, however it's far too long ago for me to remember.

Interestingly, the removal of the paternoster lift from the main library was cited as a reason not to give it listed status: http://list.historicengland.org.uk/resultsingle_print.aspx?u...

I have heard that the Muirhead Tower (at the University of Birmingham) was originally designed for paternoster lifts, but due to legislative changes was built with two regular lift shafts - which were totally inadequate for the volume of students trying to get up and down for every class. They had added a third lift by the time I was there (1997-2002) but it still wasn't enough. I hear it's been thoroughly refurbished since, though.

The Dental Hospital in Birmingham also had paternosters around that time, but only staff were allowed to use them.
