Loram High Performance Shoulder Ballast Cleaner (SBC) as the exclusive method of ballast maintenance. Over 800 km of main line has been cleaned with the SBC with minimal track occupancy (less than 400 hours). 2. RAILWAY BALLAST The railway ballast section is a layer of stones
Aug 28, 2008· In this video you see the highperformance ballast cleaner type RM 900 S in action. It is built by Plasser and Theurer in Vienna, Austria. Meanwhile, some interesting facts of .
With regards to the aforementioned railway substructure, ballast plays a crucial role in maintaining serviceability of the track and ensuring its structural capacity (AlQadi et al. 2008, AlQadi et al. 2010). The fouling process causes degradation of the original substructure, and can compromise the performance of the railway track system.
NMC Railway Systems offers the 320EL excavator package with an undercutter bar and four motor tie tamper. "The 320EL design provides increased performance and durability, which allows for easy transportation to and from the operator's jobsite," explained Chuck Haskell, sales manager.
sleepers in railway construction to distribute the loads from rails to substructure and play major role in track performance and safety. Although, different types of ballastless track have been introduced and used in the last decades, the ballasted tracks have been known as the most popular even for use for high speed trains.

— Compiled by Pat Foran, editor. For more than a century, railroads have used crushed stone (, ballast) to keep ties in place and solidify the track foundation.
His current research focuses cover a wide range of civil and railway engineering, including: civil and rail infrastructure, train/track interface and interaction, track systems, rail dynamics, structural dynamics, reliability and resilience, shock/blast and impact, high speed rails, railway and transportation systems, risks, economics, strategy, systems and urbanisation.
