I have no idea how you come to that conclusion: The 5-car Bi-mode IEP trains will have distributed traction, a similar power output to a 4-car Voyager and a lower weight than either a 5-car Super Voyager or a hypothetical 5-car Pendolino. It is well known that the Voyagers completely trounce HST timings and that distributed traction is superior when it comes to acceleration. And of course the Bi-mode trains will be running on electric power for the greater part of their journeys, instantly setting up power outputs, rates of acceleration and journey times that leave a diesel powered HST in the dust. --- old post above --- --- new post below --- According to the published figures, the 5-car Bi-mode trains will have a power to weight ratio of 11.325hp/tonne when running on diesel. This compares with 13.25hp/tonne for a 5-car class 221. There are no published figures (that I know of) for the weight of the 9-car bi-mode trains that will be used on the East Coast, but some rough calculations suggest that the power to weight ratio will be similar to that of the 5-car Bi-modes. --- old post above --- --- new post below --- Yes, electricity use is costed separately. In the current CP4 period, overhead electricity use is charged at 1.13 pence per vehicle mile for passenger trains.
