hmm, now I don't work on the railways but I think that that looked pretty mullered

Yet some people want the Southern area to have OHLE as the Third Rail gets iced over in Winter.
Heres a reason why Third Rail isnt as bad.

A tree falling on the line would have the same effect whether or not it's OLE or CR. The OLE is pulled down, and the CR will be bent and bashed. I'm not sure which is the quickest or easiest to fix though.

Got to feel sorry for anyone travelling from Liverpool Street with all the engineering works between London and Ingatestone. Let's just hope all the works (including planned) don't overrun.

I can't really agree with the critics on here.
These structures are designed with weak points where any vertical, latitudional or torsional stresses are managed without imposing destructive stresses on the stanchions and main structure. It looks to me as if the damage was contained (though not as well as was intended if the vertical alignment is present on-site and is not an artifact of the camera angle).
I'm more concerned that those fine mature trees (sycamore, beech and black poplar perhaps?) may one day be struck by higher voltages than the OHLE will ever provide, and will fall onto the line and the OHLE.

hock:In Ireland where there's around 34 miles of OHLE track, you generally get (per year) one or two overheight vehicles fouling the wires at a level crossing and three or so bikes or shopping trolleys thrown onto the wires from overbridges. Can't remember trees ever being a problem.
There are also usually 4-6 bridge strikes a year by vehicles underneath.
