"Addressing rail property in our community has been challenging, but rewarding. Through our partnership with the rail company and other stakeholders, we've redeveloped a rail yard and spur tracks into a shopping center, mixed-income housing, and a pedestrian and bicycle greenway. Our track record shows that railfields provide the economic engine and environmental quality-of-life benefits

Four-bedroom houses are ideal for expanding families or those who have several children when they move to Edinburgh. You'll find fewer houses than flats in the central areas of the city, so look to more suburban areas to find the perfect family home. There are also lots of schools and parks for your kids if you're moving to these areas, so you can find the perfect 4-bedroom house to rent

Laboratory experiments were undertaken to identify and characterise the dielectric properties of railway track ballast using Ground Penetrating Radar (GPR). Better results were obtained with lower frequency antennas. Clear distinctions were obtained between wet and dry and clean and spent ballast. The laboratory experiment is described in detail and sample radar scan plots given — the final analysis of

In this study, the dynamic properties of railway ballast, such as frequency, damping, stiffness, are studied with the consideration of effect of water. This study provides an easy tool and non-destructive method for evaluating the dynamic characteristics of railway ballast. It should be noted that this

An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. Electromagnetic coils are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, and sensor coils.. Either an electric current is passed through the

Railway track drainage has a significant effect on both the response of a rail to loading and the durability of the ballast and sub-ballast. Although various standards and design methods exist for the surface drainage there is limited information on sub-surface drainage. In particular there is a paucity of analytical or numerical studies of drainage of track foundations. The present study re

Electromagnetic phenomena are defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as different manifestations of the same phenomenon. The electromagnetic force plays a major role in determining the internal properties of most objects encountered in daily life.

Penmanshiel Tunnel is a now-disused railway tunnel near Grantshouse, Berwickshire, in the Scottish Borders region of Scotland. It was formerly part of the East Coast Main Line between Berwick-upon-Tweed and Dunbar.. The tunnel was constructed during 1845–46 by the contractors Ross and Mitchell, to a design by John Miller, who was the Engineer to the North British Railway.

The specific gravity and bulk density of the ballast are two properties that play pivotal roles in rail track safety. Bulk density is a function of the particle specific gravity and the void ratio. Two methods can be employed to increase the bulk density: the use of denser particles, and a broader gradation. Ballast with higher specific gravity can improve

07.07.2017· Acoustic properties of railway ballast. As a porous material, the ballast has absorptive properties that will have an influence on the rail and sleeper radiation. Before investigating the acoustic behaviour of the ballast, it is first necessary to determine two important and fundamental quantities: its flow resistivity and porosity. Due to the difficulties of working with full scale ballast
