This sort of thing was touted frequently by lefty press when I lived
near Cambridge - what about trams or overhead railway to cross the
city. Typical pie in the sky b/s that overlooked the narrow streets
and, in the case of overhead railway, what the residents might think
about having trains rumbling past ten feet from their front bedrooms.

Trams run in much narrower (and just as historic) streets in Lisbon and
Bologna. Although Cambridge tram routes would probably skirt the
historic centre and pass hardly any residential property.
