Railroad Maintenance & Track Laying Machine

Mon May 09, 2011 7:49 am

I don't know if this has been posted before, but i just saw it and my jaw dropped. Its freaking amazing how complex this whole process is, and yet, so simple.

Figured you railroad nutties would enjoy it!  http://www.liveleak.com/view?i=99f_1304918298

That is very cool. Thanks for posting!

I wonder how fast it takes to do the whole process... there seems to be quite a few passes at the section- how do they get one train out of the way so the next can do its job?

Yeah I wonder too. Maybe some of the train gurus on this site can explain how the process works.

There is another similar machine that does the complete opposite, it goes along and pulls up the rails and ties and leaves just a bare roadbed.

I've seen them here as well - but didn't see actually what they did before.

Sucks seeing rail lines being ripped out. This sounds rather classy; a rail line that ran past where I used to live was ripped out using your everyday excavators.

Usually these machines work in tandem. From time to time the ballast bed under the tracks has to be renewed. Also wooden sleepers tend to rott after a few decades, so they´ll have to be replaced. So you´ll have one machine lifting the old tack and removing it, then a bunch of excavators removing and rebuilding the ballast bed and finally a machine which lays new track sections, welds them together and stuffs the ballast between the sleepers.

Notice that the ties (sleepers) in the video clip are concrete. Traditional wooden ties, while not quite obsolete, are nonetheless often being replaced by concrete or composite ties.
