Much less physical intervention

with 3 comments

On BBC Radio 4’s Today programme (10 May 2018) Network Rail chief Mark Carne explained the benefit of the ‘Digital Railway‘ as he saw it.

[MC:] The exciting thing about the Digital Railway is that it requires much less physical intervention than building new railways, and that’s really why I like it so much.

So, if it’s possible to ‘increase capacity on existing lines with new digital signalling’, and this new signalling

  • requires much less trackside intervention on existing lines than traditional interventions,
  • and is much less expensive than building new lines,

then what is the point of HS2?

  1. Is this transition from analogue to digital signalling the same as the transition from “only one train allowed on a stretch of track at a time” to “trains separated by braking distances like cars”? I think HS2 assumes the latter type for greater capacity.
    However, I’ve been told that our railways are too complicated (passenger & freight trains on the same lines, traveling at different speeds) for the latter and so far, attempts to introduce it had failed.

      • ‘Digital Railway’ is a sort of umbrella term covering signalling, traffic management, driver advisory systems, and whatnot. In principle, there could be some capacity gain, even in mixed traffic scenarios.

        HS2 phase one would probably be doable without fancy signalling, but phase two would be a different kettle.
