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.
Proto:87 is a model railroad special interest group founded in 1978, providing a finescale alternative to traditional HO gauge.. Due to manufacturing restrictions and considerations such as durability, ease of operation and price, most model railroad products feature significant compromises that inhibit their viability as accurate scale models of their prototypes.
