True , and I have to admit I didn't hear any squeal when I've been on
the
Croydon Tramlink but then that took over a large proportion of
pre-existing
ex-mainline track. However the tram on the (very nice) standard gauge
NET system in Nottingham did sound rather in pain on a few corners
when I rode on it last year. That could have done with being a narrower
gauge too IMO.
