And without the massive ugly steelwork of the GWML.
The HS1 OLE mainly only spans two tracks, hence independant cantilever masts per track, closer spacing of supports, higher conductor wire tension and total freedom to place masts. GWR, limited space to locate four track OLE, longer spans, higher traffic density. Flaky headspans have proven to be a false economy.
Series 1 OLE "Ugly"? That's a subjective view. It's fit for purpose and at last function has won over style, - it's a working railway, get over it.
