For a railroad, that means replacing existing rail, ties and …
Maintaining ballast below the ties
Maintaining ballast below the ties. Optimal track conditions rely heavily on ballast maintenance. Ballast doesn't always get the attention it deserves. For those outside of the industry, the flashy signals, rail and crossties are what railroad lines are made of. But those tiny rocks are what keeps the track in place and aids proper drainage ...
Rail track maintenance machinery – Innovations in the UK
The UK rail infrastructure industry has gone through significant changes in the use of mechanised technology in the last 50 years. Large fleets of tampers and ballast regulators were introduced for maintenance and for renewals the new machinery consisted of ballast cleaners, rail cranes and tracklayers. In the 1980s new processes led to the ...
Ballast drainage in Brazilian railway infrastructures
This situation, coupled with the interests of railway concessionaires in maximizing profits by increasing the axle loads and by using a maintenance process which involves merely adding new ballast on top of the existing ballast layer, has led to several changes in the quality of the railway lines. The old ballast was buried into the soil layer ...
Ballast | The PWay Engineer
Functions. This brings us onto the functions of the ballast, once it is put down on the railway. It distributes the load of the passing trains from the rails and sleepers above it into the formation sand ground below it. It further spreads the load. It allows water to drain through it, into either the underlying ground or the track drainage.
