Steel Sleepers

[Ploughman]

Metronets version was assembled at York at the same works as the Jarvis ones but was dedicated for use on Metronet tracks. It is similar in operation but not the same I understand.

The ex Jarvis ones that still survive, I believe, are owned by a separate finance company to the rest and as such missed the scrapyard.

I believe the Kings Lynn to Middleton Tower line is steels, but the line is freight only single track with two/four workings a day

For information, steel sleepers are banned on third rail lines. They are also easier to transport than concrete, being much lighter and also "stackable" if they do not have rails attached.

Pardon my ignorance but are concrete sleepers that carry 3rd rail electrification longer than those on overhead electrified or non-electrified lines?

I only ask as steel sleepers have recently been installed on parts of Wrexham to Bidston line. So if 3rd rail electrification does ever go ahead here would re-sleepering have been needed anyway or have the costs just been increased by installing steel?

Not longer, but they are fatter, and less deep. At least when you put new ones in on 3R routes. You really don't want steel! There's quite a few between Wokingham and Ash also.

One thing that steel sleepers aren't compatible with is the Chiltern Line ATP loops. Several stretches of relatively new steel sleepers had to be replaced with concrete during the Evergreen 2 project because new signals were put in in areas that had recently been relaid with steel sleepered track.

Am I imagining it or did I once read something about third rail electrification of Bidston-Wrexham being ruled out because it had a lot of steel sleepers?

It was part of the reason why the quoted cost was so high.
