Very nice video. The machine is technically an undercutter. Ballast cleaners only pick up ballast on the shoulder, not under the ties. Undercutters are used for lowering track profile as well as removing sediment and fines in the gauge.
Ballast cleaning is very important in order to avoid water entrapment, i.e water percolating ability through the ballast, and hence avoid reduction in roadbed stability and well as the adverse effects of frost action. It is unfortunately not performed in North America, where ballast is generally added, thus raising the track. This cannot be readily done when this results in reduced vertical clearances for bridges and catenary. This scene is from a European railroad. 2017/05/04.
In this case, it's doing more excavating then ballast cleaning - looks like there's almost nothing but soil and slag between the rails. I imagine, as well, they'd have to stop frequently to empty all the soil - they were removing a LOT of it.
WOW ! , looking ahead of this trackage , I would say it Has Not been touched since it was laid . I am guessing since the forties or fifties ? . I enjoy arm chair work and appreciate this kind of video . Ray in Pa.
This is so much more professional that how it's done in the US. In the US this would be done by a rusted old dump truck on rails, a digger with the wrong attachment, and a couple of meth heads with shovels.
одлично видео. се што човек го интересира во врска со елезница е содржано овде.БРАВО

cool video ,,always wondered how it was done ,,now i know thanks 5*and a fav
what do they do with the material that was removed, is it used somewhere else, is it contaminated soil?...thanks
Great video.

Thank you for your contribution 👍 The last words got me 😅
Good video!!!
@jacero10 Under the tracks. The material is old sand,slag and soil .Everything old must be removed and replaced.
hi
How is the undercutter chain initially connected under the ties and removed at the end?
A similar machine, but pricip the same : czcams.com/video/hwHCDAod2ok/video.html Where are you from?
👌👌👏👏🙏🙏😇
@nwow2866 I guess ...the whole complex.. circa 1650 $
hey lets just dump a pile right up against what we trying to remove! GG
i am Oppereter
Does anyone know what the removed material is like. It looks pretty black. Is it oily? or, is it more like compost? What is it good for?
The removed material is dirt and finely crushed ballast, caused by the normal wear and tear.
I would think phenols from creosote leachate from the ties and possibly coal dust and it’s inherent nasties (mercury).
wow, that ballast was in bad shape. must have been a century's worth of crud built up in it.
Stupid thing to stay under the power line to film the conveyor.
For this kind of work the power line must be out of order. ;)
All that to get a few cigarette butts off the ground? 😀
