Does the beam zig-zag like the contact wire so as to even out pantograph wear?

The beams are under constant pressure in order to maintain the contact with the over head line which is why the line runs from side to side to prevent wear occurring in just one contact area hope this helps .

Yes there is still a stagger across the four foot. The beams are under constant pressure in order to maintain the contact with the over head line which is why the line runs from side to side to prevent wear occurring in just one contact area hope this helps .
There is a low tension used at the mid pont between overlaps to prevent the beam migrating, and I do mean a low tension there are no counter wieghts or auto tension units the tension for the beam is done by a turn buckle. The contact wire is held in the beam by the shape of the extrusion and insetred by a special tool, the ends of the contact wire have bolted clamps the beam has a ramp up and the clamp is right at then |

Is there a consultation on this I can send comments too? The vertical section (on the wall) needs to extend to the ground, things that stop in mid air look odd. That's the only part I can see that could be improved, there are other aspects I don't like the look of but I can't think how they could be sorted. |

Don't DOO▸ it, keep the guard (but it probably wouldn't be a bad idea if the driver unlocked the doors on arrival at calling points).

I think the council will have had vast input into this and if they're happy.....but you can try

Does it stop in mid-air? The first frame of the rendering seems to suggest it is sitting on some protruding masonry but, as the drawing rotates, that seems to vanish. Hard to tell really.

They definately stop in mid air in this illustration, though unlike the rotating drawing it looks like there may be loading gauge issues. |

Agreed - that makes it much clearer. And I'd suggest you may be right about gauging issues.

While I don't think it is likely to find universal favour, I can't think how it could be done better. It seems about as elegant as it could be.

While I don't like several elements, I can't see how it could be done better except for extending those verticals down to the ground if there is room within the loading gauge. Some images suggest there is room, others suggest otherwise. |

It is of course rather regrettable that Brunel didn't have the foresight to 'future-proof' his Great Western Railway when he built it through the Sydney Gardens in 1840.   |

I think however that Brunel would approve of this elegant solution to run OLE▸ through Sydney Gardens. No uprights on the Gardens side and the fencing looks good too.

Agreed. Not a bad design at all. My hope is that prior to installation of this, they clean and repair the retaining wall and kill off all the buddleia. Allowing trees to grow in the stonework is a much more serious threat to our heritage that some relatively tasteful OLE▸ equipment.

"The first Super Express Trains will enter into passenger service in Summer 2017, and will bring more frequent services, reduced journey times, and more seats once electrification of the line is complete."
Summer 2017? Where?
Edit - I've just noted that the Hendy Update report p88 states "Bi-mode IEP▸ trains will be introduced in Summer 2017". But question still stands.
