The probes and transducers are mounted on carriages located underneath the inspection car. Modern-day inspection cars now use multiple NDT methods. Induction and ultrasound methods can be used in rail inspection cars and operate at testing speeds of more than 30 mph (48 km/h). Increased Camera systems for detection of broken joint bars or ...
As the railroad has evolved from block stations and control towers to a centralized dispatching system, they have also moved to more advanced inspection tools. The technologies in use today vary from a simplistic paddle and switch to infrared thermography, laser scanning, and even ultrasonic audio analysis. These devices are used to inspect ...
A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
An investigation into a Colorado coal train derailment and bridge collapse that killed a truck driver is focused on whether inspection and maintenance practices at BNSF Railway contributed to the ...
Sperry Rail Service (reporting mark SRSX) is a rail inspection company founded in 1928 by Elmer Ambrose Sperry. [1] The company was the first in the world to offer nondestructive testing of railroad tracks. Since its formation, Sperry has been contracted by most of the major railroads in North America to inspect rail. To accomplish this task ...
A work train (departmental train or engineering train/vehicles in the UK [1]) is one or more rail cars intended for internal non-revenue use by the railroad's operator. Work trains serve functions such as track maintenance , maintenance of way , revenue collection, system cleanup and waste removal, heavy duty hauling, and crew member transport.
In 1995, The American Railway Engineering Association approved ENSCO’s Gage Restraint Measurement System as the only system that met standards for use of technology in railroad inspection. [7] In 1996, ENSCO began exploring techniques for tracking and location that did not rely on GPS receivers. [7]
Bogie performance detectors can provide early detection of bogie defects, and early warning of derailment risks through flange climb or rail break. [5] Bogie performance detectors most often use optical methods, and are installed adjacent to the track with wheel sensors clamped to the rails.
