That's true but why is it that we can't avoid these constant problems with the system bringing once premier lines to a complete halt all too frequently? My main point was that if we are convinced that electrification is the best way forward there need to be contingencies for this disruption such as alternative electrified routes, bi mode trains could help unless of course the alternative routes are restricted for them - if we are to care about the passengers, and of course, the staff involved. I guess I am just saying where is the contingency planning?
As I have often suggested, it is not just the contingency planning that needs to be reinforced, but also the corrective actions after events occur, and preferably the identification of the risk before they do.
As far as I am aware, the WCML OHLE is considered to be relatively robust albeit aging, whilst that on the ECML as being inadequate for today's needs. On the other hand, I understand that all pantograph systems in use are considered generally suitable. The result is that there is no easy solution even on the WCML, but but improvements must exist otherwise how does e.g. the SNCF apparently have a better record even on their high-speed lines. Hopefully, even before a robust HS2 is available, time and money will be spent to improve the current WCML and to rebuild the ECML.
A second significant issue is the robustness of certain signalling, where I am sure that the way to go is to improve its robustness rather than use temporary workarounds.
