Re:The problem with our railways is not speed (Score 3, Interesting)

the problem is more just that it's old and is still based on design decisions made years ago. the lack of capacity and the higher cost are just by products of this. The height of trains is limited by all the tunnels about, which will be a major engineering work to increase, the length is limited by most platforms and the width is limited by the gauge. these things were all chosen a long time ago and we just keep trying to sticky plaster over it. basically, we got stiffed because we were early adopters
