GWR OLE is Network Rail Series 1 sysytem designed by Swiss specialists Furer+Frey. The cantilevers actually look 'designed'. The problem is the huge scale of the components, likened to container ship mooring posts.

The auto transformer wire hasn't been installed yet. Too high.

The huge structures on the recent GWR electrification are also ideal for mooring container ships to.

Interestingly, the cantilevers look 'designed'.

Rail: You reviewed the design of CTRL2 in your last issue, the architect waxing lyrical about his engineering solutions, but OLE was hardly mentioned. However, if you drive down the M2 or M20 motorways you cannot think that the CTRL has enhanced the beauty of Kent as the over-tall masts are visible everywhere, protruding from cuttings, spoiling the Medway bridge and silhouetting against the sky.

The poles dwarf the train.

High dark TGV design masts hang over the parallel M20 for some distance. Not pretty.

Just how high do those masts have to be? Medway viaduct, CTRL channel Tunnel Rail Link

New station built around the original Liverpool WCML electrification (using copper wires). Existing structures sit in pits in the platform including greasy weights. Extremely tall staircase/escalators span the full height OLE.

Harmless 60s WCML low level portals (with supporting wire running over the top).

New cantilever contrast with original poles, extra height, stronger heavier structure.

Early 25kV systems in the UK (including North Staffordshire) used round poles - very acceptable.

Cantilevers mar the London skyline.
