Railway lines

I was asked what kind rods I would use to build up worn rail track, well I haven't got a clue, has anyone else.

for what purpose

 

[mechman]

I believe it was some worn point mechanism

 

[Brad93]

I would leave that to the engineers, I doubt any small firms Insurance would cover them for train tracks carrying upwards of twenty tons of locomotive with or without passengers.

 

[HMB]

For network rail??

20t loco? Tiny one then

If we are talking about a genuine rail line. There is a list issued by whoever replaced British Rail Engineering. These days Im not sure whats on it.

 

[HMB]

If it's a pway job for network rail the es will have everything told to him. Normally they'll just swap it out

I have seen that fusion type where they weld two tracks together but not stick weld for building up worn track. I don't do stick weld just curious

Thermit welding

 

[pedrobedro]

They don't build up worn track they replace it with new. Thermite welding is used to join lengths of track..

 

[HMB]

Did say that earlier

They used to do repairs.......they have a name for the spots where the wheels spin...whatever it is they used to repair them

I've just recently finished a big project with Network Rail track crews, the only welding they do is Thermic welding when joining two sections of track together, the weld that sits proud is ground back to a radius profile using some trick engine powered grinders.

On worn track points etc, these days they dress the surface a little to get some more life out of it but don't ever do any buildup up welding of any sort.

"they have a name for the spots where the wheels spin..." : rail burns ?

Don't worry guys.will go there if needed and slap a slug around it.got little 130 stick.do the job a treat

They dont they never have. The thermit welders dont do anything else. Its a different crew that used to do it. I know someone who is building a Wagon that is positioned over the rail specifically to repair worn rails so I assume there is a need for it.

I used to be a member of this lot........http://www.iorw.org/ but I dont have access these days

While I'm not an expert in this I understand that that the waggon being constructed is most likely to be some sort of automated track grinder because because the biggest risk experienced by any of the various track crews is exposure to hand transmitted vibration when grinding track. This risk is more severe as all track crews work at night when it's generaly colder. I've reviewed crews and all THIER kit up and down the country to understand vibration risk and even been to two Network rail training centres and not seen any kit to do build up welding on worn track.

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

bet they are repairing them in India
