Just google "weld Repair Rails" and there are loads of articles

We in the UK may have stopped but we definitely used to repair them back in the day. I was at the inaugral IoRW meeting possibly 12 years ago, maybe more, when it was discussed for the first time. I recall the Railways Expert on welding was a Geologist who had the stock answer "I dont know Im a geologist". After a while I suggested they may be best advised to employ a Metallurgist..

Most of the consumable manufacturers make consumables specifically for rail weld repair.

and the waggon being designed does grind but it also welds and NDTs the finished joint...........maybe its intended for Europe of elsewhere..I dont know

I bow to your superior knowledge but I think the key is in Joint, all tracks these days are joined end to end by thermic welding so the ride is smooth (no bumpety bump). But I'm not aware of any track being built up with welding and reprofiled. Worn track is simply replaced if it can't be ground back to spec.

This new waggon I suspect is as a result of some of the work I've being doing over the last few years where we found the risk of exposure to HAVS was unacceptably high and a huge number of industrial claims being made

bet they are repairing them in India

I don't think they repair anything in india

they have a loco in india that uses 3 rails the 3rd has teeth to help it climb the steep hills, they are still using a hammer and percussion drill bits to bore holes in the rocks that fall on the lines in order to put dynamite in and blow them apart to move them

Theres one that goes up Snowden....Funicular Railways or Rack and Pinion railways I think they are called

I was in India a few years ago in a place called Ludhihana, it's an engineering / steel city bit like Sheffield. Was at a place where they make gates and grilles etc, the workshop had the most basic of tools and a very dodgy looking arc welder. Two boys were cutting square bar to length using a big lump hammer and cold chisel

There's one in Lynton too that takes you up the cliff, not sure if it's as you describe or if it uses a cable, but it does make a clicking sound on the way up

sounds familiar

The Lynton / Lynmouth one uses water to drop one carriage which lifts the other............Similar in scarborough where one counter balances the other. On grander scales is the Llandudno one which has a really long cable thats used to pull it.
Been on them all............Im a geek deep down

There you go, that's a new one on me, didn't know it used water, those Victorians were clever people!

Can you imagine this forum if any of those legendry engineers were around now

 

[daleyd]

I think Snowden is the only rack and pinion one in the UK, the others are the "funicular" types which use the cart going down to pull the cart going up.

Network Rail repairing a crossing. Doesnt mention the wire but it must be a self shielded. I think its made by Welding Alloys http://www.welding-alloys.com/filea...onal_literature/Railway-crossings-repairs.pdf

I take your word for it and the video evidence presented but this wasn't presented to me in any of my works with NR. We did quite a comprehensive exposure evaluation excercise and this was clearly missed out. I will check in a couple of weeks as I'm going to THIER head office in Milton Keynes

Used to put a zig zag weld on the rail top to improve track circuit continuity, particularly in bay platforms where idling diesels contaminated the rails - I never did it myself but was told the rods had a high chrome content.

HTH

they might have stopped doing it. i dont know whats happening now........just what used to happen..........the thermit welders never did arc welding so maybe thats the reason...

Ok I think I've got the definitive answer now ( maybe quite possibly), speaking to one of my contacts he confirms that once upon a time they did a lot of build up welding followed by lots of grinding but due to two reasons this was stopped.

One because there was a lot of time required for dressing the welds and with track possession time being reduced this practice was done away with to simply replace track

Secondly there was major risk of exposure to HAVs and with a huge rise in claims they decided to minimise as many jobs as they could to reduce HAVs exposure, hence just replacing track with minimal grinding required.

I think this explains why this was never highlighted to me in my works and why they didn't have any kit

 

[TechnicAl]

Oh OK......I would have thought repair was quicker than replace but .....Im never surprised by things the Rail company does

Out of interest they have 26000 workers and contractors and over 2000 claims for HAVs, I can see why theve reduced all jobs requiring grinding

sounds like an epidemic

Inclined plane railway? seen the one at Ironbridge and been on the cliff railway at Bridgenorth
