I was reading an article on rail magazine about why Grand Union sold their rights to Lumo, and this line seemed curious to me.
The part about ATP aside, why does he think they couldn't hit 125mph? That was their designed speed wasn't it? And they had better acceleration than the HSTs that were until recently used on the GWR mainline?
Initially, Grand Union wanted to use Class 222 diesel-electric multiple units, but Managing Director Ian Yeowart said these units would be unable to reach their 125mph top speed.
The ‘222s’ are not fitted with Automatic Train Protection (ATP), which is in use on the South Wales Main Line between Paddington and Chipping Sodbury.
Even if fitted with ATP, they would be limited to a maximum of 110mph, meaning they would have been unable to keep to the South Wales and Great Western Main Line timetables, which require 125mph running.
