The HST has 5000hp, the 442 has 3300hp, and weighs about 70 tons less.

The HST control gear is much more modern too, so I would expect the HST to be quicker off the mark. They're probably pretty much the same in reality, though.

I'd say there would be now contest up to a certain point, the 442 would win hands down. Electrics tend to have much more torque low down (raw power to turn the wheels), regardless of basic hp, but there's be a point where you just wanted to go faster and faster, which I expect would come quite a bit before the 442's 100mph max, and beyond that I think the HST would win.

A race to 100mph, or to a distance over which both could reach 100 could be very interesting IMHO.

To correct AD's figures, a 10-Wes will produce 3200hp (2.4MW) at rail, whilst a HST has 3500hp (2.64MW) at rail. Assuming empty vehicles (and the 70-tonne figure is fuelled weight for the '43s'), the difference is only 20 tonnes (405t for the 10WES, 425t for the 2+8 HST). Then it becomes a question of Tractive Effort and gearing - and if anyone has the TE curves for Wessies and HSTs, please don't keep quiet about it! I suspect the HST would win overall, but would be behind to begin with, then catch up and overtake as the aerodynamic effects really start to kick in.

Having driven just a few HST's out of Paddington, and having been a guard at Basingstoke for a few years, I would say that the WES would win, but not by much.

id have to dissagree with matt on the fact a 158 cant travell at 100mph whilst i was working for central trains i was in the rear cab of one on a stanstead - liverpool train and we were fastlined out of stafford the guard looked at the speedo which i found suprising to see it read the speed we were travelling and we were at 102 before the driver notched down, saying that we were 10 minutes late and a 3 car formation. Apparently happened on a regular basis untill the 125mph line increase.

Thats Just sounds like a MSTS 158 you where on,not a real one
