Maintenance Of Railway Track

Maintenance of railway track

Under the action of train repeated load and the influence of climate and environmental conditions, each part of the track will produce wear, corrosion, decay, fatigue damage and residual deformation. At the same time, it will also change the track geometry such as gauge, level, direction and height. If these changes are not eliminated in time, they will aggravate the impact and vibration, and even cause derailment, subversion and other railway accidents.

The main work of track maintenance and repair includes rail oiling, lubrication and grinding, maintenance and repair of turnout, replacement and supplement of track bed ballast, reinforcement and maintenance of subgrade, bridge and tunnel, etc. For the busy railway trunk lines, relying on the past manual road maintenance operation mode can not meet the requirements. We must adopt modern detection and railroad maintenance technology and modern railroad maintenance machinery and equipment.

At present, the commonly used railroad maintenance machinery is divided into overhaul machinery, maintenance machinery, inspection machinery and repair machinery. Specifically, it is divided into large-scale screening machine and supporting maintenance machinery, rail grinding vehicle, rail flaw detection vehicle, track inspection vehicle and other railroad maintenance machinery, as well as line tamping vehicle, ballast cleaning vehicle, line power stability vehicle, slope shaping vehicle, turnout tamping vehicle, line overhaul vehicle, etc, Using these equipment can greatly improve the operation efficiency and maintenance quality, so as to restore the performance of each component of the track and keep the track geometry in good condition, so as to improve the quality of the line and ensure the transportation safety.
