In recent years, the ballasted track structure is widely used in many countries due to its low construction cost and high performance in rutting resistance [].However, reports concern the great deterioration of the ballast structure due to the continuous loads from high-speed trains and environmental impacts [2, 3, 4].Hence, many strategies have …
Ballastless track. The demands on the track systemhave changed greatly since the start of railways. This applies not only to parameters such as axle load and speed, but also less obvious factors such as train length and frequency. In addition to the classical designof track gridfloating in ballast, other non-conventional designs have been ...
The accelerations of the rail, sleeper and ballast in both the time and frequency domains prove that the installation of the ballast mat can enhance the resilience and elasticity of the ballasted track. The ballast mat can effectively reduce vibration at the mid- and high-frequency range of 40–3000 Hz with a maximum vibration reduction of 15 ...
Plasser & Theurer offers sturdy and high performance track renewal and track laying machines that operate in continuous working action. The integrated material logistics organise the transport of sleepers and rails to and from the worksite over the newly laid track. Alternatively, we also offer compact renewal systems that work in cyclic action ...
Maintenance to restore the design level is usually by tamping. In this process, the track is raised and vibrating tines inserted into the ballast to squeeze it horizontally in the direction of the track, raising the level of the ballast surface. This reduces the density and disturbs the structure of the ballast, which has become established ...
All the aggregates came from Italian production plants. One "artificial" aggregate (steel slag) was used to assess if it can be used instead of the natural aggregate on a railway line in Italy. ... So far, the steel slag aggregates have been successfully used as ballast on railway track construction in the USA, Brazil, Canada, Iran, Spain ...

For example, the new BTE 318 wheeled-excavator with hi-rail is a "one-machine surfacing system," the company says — it can undercut, tamp, move and place ballast from on- or off-track ...
The team consists of the RST-1000 production switch tamper and RBR-1000 production ballast regulator. ... excavator models for quick access to remote track lines. The hi-rail excavators also can ...
Quality of stone ballast required per metre tangent length of broad guage is 1.11 cu.m and for metre gauge, it is 0.767 cu.m. Minimum depth of ballast for broad guage is 250 mm and for metre guage it is 200 mm. Width of ballast for broad gauge track is 3.35 meters and for metre guage track is 2.3 metres. Types of Ballast Used in Railway …
The job involved a track gang of men who would push the ballast beneath the ties one at a time and track jacks were used to properly align the rails. ... Using what is known as the Delta System developed in the 1950s production tampers are able to remove the bumps and dips in the rail by aligning the track to a perfectly "flat" traveling ...
CaO and SiO 2 are the main components of SSA for different processes of production, such as BOF, EAF, and Ladle slag [].As shown in Table 1, SSAs have approximately the same mechanical behavior as mineral aggregates [12, 15].The higher density of particles could be a positive characteristic to enrich track stability. As …

1. Ballast keeps vegetation from growing on railway tracks which could weaken the ground on which the railway lines run. 2. Ballast also keeps water from reaching the track on a regular basis and softening the ground. Therefore, the stone around tracks is always sloped downward, away from the tracks.
A field trial was conducted on an instrumented track at Bulli, New South Wales, Australia, with the specific aims of studying the benefits of a geocomposite installed at the ballast-capping interface, and to evaluate the performance of moderately graded recycled ballast in comparison to traditionally very uniform fresh ballast.

More specifically, the railway track is the superstructure placed on the top of the railway body. The traditional railway track basically consists of a flat framework—obtained by properly linking rails, sleepers and fasteners—and a layer of crushed stone called ballast. Below the latter, if necessary, a further layer called sub …
On-track machines offer higher productivity rates, but have more impact on train traffic. Large production undercutters can be capable of cleaning the removed ballast and returning usable material to the track bed. Additional ballast may still be needed, and the track will have to be brought to the desired grade and tamped.
Undercutting is needed to restore the desired ballast properties after becoming fouled. Undercutting is the continuous excavation of the material beneath the ties. The material excavated can either be fully wasted or screened and returned to the track with only the fines being discarded. Loram offers two automated undercutter platform solutions ...

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 ...

Our High Output Track Renewal System (TRS) and Ballast Cleaning System (BCS) allow us to replace track and clean ballast quickly overnight while trains continue to run safely on adjacent lines. Working overnight is essential because the railway can't sustain the amount of weekend access we'd need to deliver such a volume of renewals.
When planning the railway track to meet this surge, engineers need to consider a variety of factors including train speed, load intensity, frequency of train passes, subsoil stiffness, cost ...
