Eurostars quieter than Mark IVs + Class 91s?
This may not be the right forum for this question, but what the hell!
Standing at Hitchin station and wistfully watching the fast trains
going through, the wheel-on-rail noise of class 91 + Mark IV coaches seemed
much louder than the Eurostars. (Comparisons with HSTs are difficult because
of their noisy diesel engines - at full chat as they pick up speed going
North). This was just a casual observation. Is this generally accepted? Are
the reasons known?
