A ballast cleaner Matisa C330F in action on the Coastal Railway in Haifa, Israel. A ballast cleaner (also known as an undercutter, a shoulder ballast cleaning machine) is a machine that specialises in cleaning the railway track ballast (gravel, blue stone or other aggregate) of impurities. [1]
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]
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.
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.
A ballast regulator (also known as a ballast spreader or ballast sweeper) is a piece of railway maintenance equipment used to shape and distribute the gravel track ballast that supports the ties in rail tracks. They are often used in conjunction with ballast tampers when maintaining track.
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 ...
Whilst the scale of structures can be considered the same in an O Scale layout regardless of track gauge (ignoring forced scale for purposes of perspective), On3 (3 ft (914 mm)), On30 (2 ft 6 in (762 mm)) or On2 (2 ft) prototype modelling permits a greater level of model detail and more appropriate scale operation of narrow gauge railway ...
