Basil Jet remarked:
Viewed from the road bridge, it looks as if the electrification masts
for the new third track foul where the fourth track would go. I thought
all of the present work was supposed to allow passive provision for
Crossrail 2?

Wouldn't OHL be an active provision, rather than the passive provision
of a trackbed?
