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]
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.
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.
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.
Code 83 track was introduced in 1985, giving layouts more realistic proportions. In 1990, the Cornerstone Series buildings were unveiled. Combining a freight car with a related industry, the Cornerstone Series makes it possible for modelers to duplicate authentic operations, enhancing layout realism.
