Shoulder Ballast Cleaning Guidelines - ARTC

•Screening Car – removes fines from shoulder ballast; size and shape of screens can be varied to suit conditions. •Ballast return - % return can vary depending on size of existing shoulder, age of ballast and screen size; generally 80 - 90% ballast return is achievable. Recovery of excess ballast will reduce top -up ballast required.

Track renewal train - Wikipedia

After the track renewal train completes the tasks, the ballast will be put back on the track. For track renewal trains that do not have ballast excavating machines included, workers will use a shoulder ballast cutter machine that takes excess ballast that has been pushed out during the track renewal process, into a screening and cleaning machine.

Track ballast - Wikipedia

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track

Model Rail Forum > Ballast shoulder - purpose?

Nov 06, 2007  On modern welded track with heavier flat-bottom rail, I understand that the depth of ballast is greater to help hold the track more firmly. Also the concrete sleepers are greater in depth? And on a curve the super-elevation on the outside of a bend also creates a deeper layer of ballast. The shoulder is normally a 45 degree (1 in 1) slope.

Ballast bed resistance characteristics based on discrete ...

In general, the ballast track bed shoulder width in noncontinuous welded rail tracks is 200–300 mm and in continuous welded rail tracks is 400–450 mm. In the discrete-element model, we use ballast bed shoulder widths of 200, 400, and 600 mm to study the effect of shoulder width on the lateral and longitudinal resistance of the ballast bed.

Jun 01, 2017  Le Pen and Powrie (2011) present the opinion of the European Rail Research Institute (ERRI) that sleeper crib and base ballast contribute approximately 1/3 each to the lateral resistance of the sleeper on unloaded track. In this case, a ballast shoulder with typical dimensions should provide about 1/3 of the lateral resistance.
