A lot of industries in Toronto and the surrounding parts of Canada depend on proper drainage services. Drainage services are not only found serving homes and buildings. They also work on railways. All railways running through Toronto depend on a working drainage system to ensure optimal railway safety. Good railway companies use a combination of techniques to properly drain a railway track. These techniques include the use of radar, ditching, specialized excavations, track lifting, shoulder ballast cleaning, and undercutting. An under cutter is a machine that lifts up pieces of the track to create a sub ballast layer.
