I was just travelling to Watford and noticed significant stretches of the fast lines have these new conductor rails like the ones I saw at Wood Lane last week. They look much shinier and a bit smaller than the old style. Are these going to appear throughout the entire network soon?

This has been discussed before, a thread archaeologist might be able to dig it up... But IIRC the SSL lines will be getting the new (Ally?) conductor rails as part of the power upgrade in preparation for S-stock.
I wouldn't know whether tube lines will see conductor rails replaced with this sort in the future though...

I wouldn't know where to start looking for such a thread  ;D ;D Track replacement at East Ham last weekend saw aluminium conductor rails installed. I think it's just the way LU are likely to go in the future rather than being critical to the power upgrades. I was chatting to a Pway chap in my cab last week and he did mention the power upgrade project. He appeared to suggest that the main issue was cable replacement to handle the higher voltages. |

It's aluminium with a stainless steel top rubbing surface. It has much lower electrical resistance than traditional steel conductor rail so the electrical losses are reduced. This helps when trains need a bit more current and is usually more cost effective than building additional sub-stations which would otherwise be needed to give enough volts and amps at the train. There are a few additional sub-stations to come for S stock as well.
With regenerative braking, the reduced losses help in the reverse direction too when the braking train is exporting power via the conductor rails to other trains.

Now to be seen on most of the Hammersmith branch, and sitting waiting to be installed in the cesses and 6-foots of most of the city area of the H&C.

Does the removed conductor rail get cascaded elsewhere if its still of decent quality? I'm thinking of some of the ropey bit of conductor rail seen in sidings for example.
