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]
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 chloridometer is a measuring instrument used to determine the concentration of chloride ions (Cl –) in a solution.It uses a process known as coulometric titration or amperostatic coulometry, the accepted electrochemistry reference method to determine the concentration of chloride in biological fluids, including blood serum, blood plasma, urine, sweat, and cerebrospinal fluid.
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.
General view of part of the rip tracks at the Chicago and North Western Transportation Company Proviso Yard, Chicago, Ill. April 1943. A RIP track, short for repair in place track, [1] [2] (also known as a "cripple track" in slang terms) is a designated track, or tracks, in a rail yard or a siding along a section of a main rail line where locomotives and/or railroad cars can be placed for ...
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.
