LCA comparison of slab track vs. ballasted track

International Conference on Road and Rail Infrastructure
When it comes to reducing the rail systems' ecological footprint, it is essential to assess and compare lifecycle (LC) greenhouse gas (GHG) emissions. In the presented study this is executed for the two main railway track construction types: ballasted track and slab track.

Frost-Thaw Effects on Ballasted Track

Transportation Research Record: Journal of the Transportation Research Board, 1996
The multiple failures of a ballasted track 877 m long built to guide the wheels of a heavy gantry crane used in a logging yard in northern Alberta, Canada, are described. At the time of construction the crane was claimed to be the heaviest, and its wheels were supported by a ballasted track with wood lateral members (ties). The track was built in 1985

Behaviour of Track Ballast Under Repeated Loading

Geotechnical and Geological Engineering, 2013
Najaf-sea quarry is located in Najaf city about 160 km south west of Baghdad the capital of Iraq. It is the main source that supplies track ballast for maintenance of existing railway network and construction of new railway lines in the middle and southern parts of Iraq.

Infrared thermographic investigation of railway track ballast

NDT & E International, 2002
Abstract A theoretical study was undertaken to determine if infrared thermography is an appropriate method to identify the condition of railway track ballast. Within this study the optimal conditions for an infrared survey were established. A laboratory experiment was undertaken to identify clean and spent ballast using an infrared camera.

Lateral Stability of a Ballasted Curved Track

Journal of Transportation Engineering, Part A: Systems, 2020
AbstractThis paper investigates the status of lateral stability of a ballasted curved track, which is carried out under four loading scenarios in terms of the factor of safety against displacement ...

Dynamic Train-Track-Ballast Interaction with Unevenly Distributed Track Properties

Vehicle System Dynamics, 2002
ABSTRACTA numerical method to simulate vertical dynamic interaction between a rolling train and a railway track has been extended to account for stochastic properties in the track structure. Here, the rail pad stiffness, the ballast stiffness, the dynamic ballast-subgrade mass and the sleeper spacing are modelled as random variables.

Track stability using ballast bonding method

2010
Ensuring the high speed rail traffic, increasing railway track capacities, providing comfortable and safe ride as well as high reliability and availability are the most common demands put on the railway tracks nowadays. Consequences of the mentioned are highly increased loads, not only on the superstructure, but also on the ballast bed.
