Introduction You arrive at your new modern architect design station and admire its design, in glides a train with an elegant front end looking sleek and fit for purpose. Then you look up and see the overhead electrical wiring that feeds electricity to the trains - and your heart sinks. The brutal mish mash of grey metal structutres that echo electricity pylons ruins the skyline. Is this the same railway? When you look around at new railway electrification you start to think what a missed opportunity this was to add to the quality of the built environment. After all, they do it in Europe and Asia. |

Height Traditionally the easiest way to get electricity around was to string wires between poles. Putting the wire underground is expensive and can have running costs in terms of cooling. In the UK lower voltages in towns have gone underground, but look at much of the US which due to the use of overhead power lines for domestic electricity suppy looks extremely scruffy. Sticking the wires up in the air keeps them cool and away from people, they're dangerous after all. And so electrical engineers see air as a free resource, it doesn't have to be paid for. So they can go as high as they like. And without planning permission. Current railway OLE has grown in height to add new auto transformer wire technology and, supposedly, to allow easier installtion of all wires underneath horizontal beams. And taller means bigger. Would the structures be so high if there was a cost, say an environmental damage tax? After all, the higher you go, the bigger the impact. Nobody complains about low things. Some electrical engineers say that noboddy cares what it looks like as long as they get reliable trains. How depressing. There is no incentive for OLE engineers to keep their structures low. Because the taller a structure gets, the more responsibility the builder has to his neighbours. |

Good design A RIBA competition in 2014 produced some exciting new 'aesthetic' design ideas. But they were all rejected by the rail industry, despite being designed by engineers. At the time it was reported positively in the rail press, including the trade press. https://www.ribacompetitions.com/ols/index.html Lip service A Network Rail document: NR-GN-CIV-100-05-Heritage-Care-and-Development-Module_19.09.20 purports to show care for the environment and quotes GWML electrification as a success story for the environment. Yet it was a disaster. |

Aesthetically pleasing structure for sensitive area. Round pole. Can't we have this everywhere? Why does Bath get better than everyone else? |

Sensitive areas There does seem to be agreement that there are sensitive areas through which the railway passes, areas of natural beauty and urban environments. Hence special designs in St Pancras train shed and the Durham and Berwick (Royal Border Bridge) viaducts. But isn't everywhere a sensitive area? Or put it another way, what are insensitive areas? What if the same rule applied to buildings? Our housing would look like that in the ex Soviet eastern block. When the engineers say the appearance of OLE is subjective you know they're arguing a lost cause. There are many locations where the industry recognises that OLE must suit the location - Berwick, Durham, Sydney Gardens Bath, St Pancras trainshed and most recently it has been suggrested by Transport Scotland that the Forth Bridge would require a careful electrification design to befit its World Heritage Site status. One practical realsisation that overhead is ugly is the new catenary free extensions to the tram network in Birmingham. |

Cost OLE costs squillions. And don't think of altering anything once its up as that costs a fortune too. OLE masts are made in standard lengths so they're always tall enough for the job, less accuracy in the surveying. These over tall masts are not shortened once installed as its easier to leave all that metal up there than cut it off, take it away, and recycle it. There is a history of cost overuns, with GWR, Northern Hub and Goblin delays and cost increases due to design and engineering errors. |

Trust And do we trust the secretive electrical engineers? They always tell us its fine, that they've learned by their recent mistakes, before they mess up again with bad designs and over budget results. |
|||||||||||||||||||||||||||||||||||||||||||||||||||
Professionalism Their seems to be a big mistrust from the electrical engineerss of other disciplines that have offered fresh ideas, architects and designers. Hence rejection of all the RIBA ideas for example. |

It is majestic, daring – and a destination in itself. This glorious new station in Belgium is the future of train travel. With designer OLE gantries. https://www.theguardian.com/artanddesign/2009/sep/16/liege-guillemins-train-station |

Lack of imagination How did Network Rail think it was alright to use the Master Series, not just in the Goring, but on the whole line. How could they do that? I read that many of the residents of Goring are barristers but they got nowhere in their 3-year battle to hold NR to the promise to reduce the visual impact of the OLE. Read the sorry tale on the links page. And the Goblin Wansted viaduct OLE - ugly cantilevers mounted on one side. What a missed opportunity to enhance the appearnce and introduce an art form into the landscape - hoops for example. OLE engineers are missing the opportunity to add beauty to the landscape as well as electricity. |

Despite the trainshed (behind the photographer) being grade 1 listed and the award winning new western concourse, standard heavy weight OLE was used in the 2021 remodelled throat instead of headspans. |

Alternative texts One might argue that the best design is functional, and that OLE is actually beautiful, the result of the elctrical engineers (dark) art. And on plain line this may be true, with equal spacing, the zig-zagging of the wire and the harmony with the alignment of the route. However, where people come into contact with the railway, in cities, towns and at stations the OLE is more likely to be a mess with lattice work, high level electrical line feeds, extra tensioning sytems and the inevitable H-section masts sawn off at different heights - all plonked around in an almost random manner - and all in delightful light grey, or if you’re unlucky, in varying shades of rust brown or yellow primer. |
