Did anyone else spot "Some level of onboard energy storage may provide
an optimal solution overall"?

If you are only running on core routes, surely there will almost
always be other trains in the same section to use the regenerated
energy? North of the Thames, energy could be exported to the grid
anyway, and inverting substations could be considered for the SR
routes.

Energy storage is surely needed only for extremities of the network
where traffic is light - Seaford, Arun Valley, etc. I can't see it
being a problem in the metro area or Brighton main line. Or is it
just in case units have to limp out of sections which have suffered a
loss of traction supply..?


Almost certainly the latter, by the sounds of it.
