The Railway Supply Institute said in 2015 that Loram was "one of the leading suppliers of track maintenance machinery and services in North America and the global market". [2] Every Class I railroad in North America uses its equipment, and it is widely acknowledged to be the industry leader in grinding equipment. [6]
Handheld inspection devices are very useful for this when the track is used heavily because they can be removed relatively easily. However, they are considered very slow and tedious, when there are thousands of miles of track that need an inspection. Rail inspection cars and HiRail trucks are the answer to today's high mileage inspection needs ...
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 ...

A track crew in Louisiana adjusting a railroad track using lining bars, in 1939. The most fundamental maintenance of way task is the construction, repair, and replacement of the track and its supporting ballast and grade. In the early days of railroading, this task was almost entirely completed by manual labor.
A 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.
This is a combination of accelerometers on the track, and another accelerometer installed in the bedrock next to the track. The correlation of these measurements indicates how much track-born noise is propagating through the ballast into the bedrock strata. This correlates directly with the noise levels experienced by surrounding area.
