Comparing Ride And Perceived Performance In Class 170 And Class 755 trains

I had intended to go to Norwich and Sheringham today, to take some pictures of Class 755 trains at Sheringham station.

Unfortunately, when I got to Norwich, the Sheringham train was a Class 170 train, so as I was running late, I came back.

But as I had travelled to Norwich in a twenty-year-old Class 170 train and returned in a brand-new Class 755 train, I was able to compare their ride and passenger performance on the well-maintained and straight Breckland Line.

The Class 170 train has a good ride and I’ve never felt to complain, even when travelling at 100 mph on some CrossCountry and Greater Anglia routes.

But I did feel that the Class 755 train had a smoother ride.

I did time the 755 at 90 mph on parts of the route, but at most times it was doing a motr sedate 75 mph.

Could it be that twenty years has enabled train dynamics to have been improved using computer simulation?

Intriguingly, the three-car Class 170 train is twenty percent heavier and has half the power of the four-car Class 755 train, which probably results in more sprightly acceleration for the new train.

Could this acceleration mean that the trains will be faster on a route with lots of stops?
