You can't run freight and passenger trains on the same strecth of line, with passenger trains running at 90MPH......?
Well, in that case we will have to rewrite out entire operating rule book over here then....
They are about to run freight over HS2 (so that is 75MPH freights over an 186MPH railway) shortly.

Not familiar with the loaded weight of a freight car in the UK--how does it compare to the 100+ ton cars here in North America?
I know in the US, it has been stated, by Graham Claytor I believe, that just one loaded unit train traveling on the NEC places measurable degradation on the roadbed which has negative effects on the passenger ride quality.

In the East, where passenger density would most be able to support HSR, the existing rights of way were laid out in the 19th Century by surveyors that had no knowledge of SPEED and laid out the rights of way to best facilitate the movement of tonnage and did this by using curvature to minimize grade. As such the existing rights of way are not compatable with HSR for the most part. Secondly, since the rights of way were built in the 19th Century, homes and industries have been built right up to the railroads property lines in the ensuing 175+ years, making the proposition of widening the existing rights of way a check book and emminent domain issue.
A second problem in following existing rights of way is that the railroads own facilities (yards & terminals) are not exclusively on one side of the track or the other and would have to be bypassed by some means.
If we are to have HSR that is what it is supposed to be, the route and it's engineering have to be done as the best the 21st Century can provide, not a cobbled fix to a 19th Century plant. In the East, traffic, both air and highway, becomes more congested daily. Unless Billions are spent on HSR, Trillions will need to be spent on Highway and Airports to handlle the traffic increases as our country's population continues to expand.
Bucyrus BaltACD: But in my view, even if HSR were given its own track on an existing freight corridor, there would still be considerable impact on the host railroad's operations, especially in the necessary re-working of the corridor, including grades, alignment, drainage changes, new bridges, modified crossings, etc.
