Examples from today would be eastbound start from Bath. IET did well to Bathampton Jn and matched typical HST time, but after that HST romps away and going 15 mph or more faster out of Box tunnel.
IET did well from BPW to Westerleigh Jn. But 96 coming out of Sodbury Tnl ebd compares with 110 for an HST. I'd call that no contest!
Met up with various colleagues from RPS today and we are chewing over our first impressions, but initial consensus is like the train, but its underpowered on diesel.
On electric it will be no contest again.
Is this WITH the software mod to uprate the engines?
