I have no idea on that. But being a Cambridge boy and being taught by a train enthusiast teacher in primary school who told the class 1 day (when on a visit to Cambridge South box), what I posted above (ie didn't want dirty steam trains in "their" town!
I can well believe the thing about 'ladies of the night', however I'm guessing the teacher left that bit out as the class was 9 year olds!
My understanding was that because even then, the temptations of London would be too great were the railway station in its originally planned location (Christ's Pieces, which is as central as you can imagine in Cambridge).
As an aside, there is a saying that you can walk from Cambridge to Oxford without leaving University land! Yep, they really do own that much! I believe Felixstowe freightliner terminal is owned by Trinity College.
The latter is true, the former is not. I think it may have been true some time in the 1800s, but there are large gaps now (obviously - for this forum anyway - the many railways in between, which are of course owned by Network Rail) The O2 Dome is also majority owned by Trinity College, Cambridge, they own an awful lot of stuff.
