Railroad Ballast Improvements Using GEOWEB® Geocells

Sep 03, 2020Impressive Research on Railroad Ballast Improvements Using GEOWEB® Geocells. Every year, railroads dedicate a great deal of capital and maintenance expense towards the creation and upkeep of high quality ballast layers. Enduring well-designed ballast is quite literally the foundation on which a successful rail line operates.

Ballast maintenance update: Better, faster ballast

“The exclusive BTE four-wheel hi-rail system provides power for on-rail ballast maintenance,” Weyand said. The BTE hi-rail system allows BTE’s hi-rail machines to be used on or off rail with a quick change. The BTE-325 can be rapidly deployed on rail and easily jumps off-track for more versatility or to allow train traffic to pass, the

If ballast is badly fouled, the clogging will reduce its ability to drain properly. That, in turn, causes debris to be sucked up from the sub-ballast, causing more fouling. Therefore, keeping the ballast clean is essential. Bioremediation can be used to clean ballast. It is not always necessary to replace the ballast if it is fouled, nor must all the ballast be removed if it is to be cleaned. Removing and cleaning the ballast from the shoulder is often sufficient, if sho

Railroad Ballast, Types And Purpose

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).

Specifications for Track Ballast

The following specifications of ballast, which have recently been revised (June 2004), are followed on Indian Railways. These specifications are applicable for the stone ballast to be used for all types of sleepers on normal tracks, turnouts, tunnels, and deck slabs on all routes.
