Rail Milling – the Start of a New Era in North America’s Rail Maintenance

++Toronto Transit Commission (TTC) awards Rhomberg Sersa North America | Linmag Partnership a 3 year frame work contract to mill their rails on their subway network++

Rail milling will be used for the first time ever to re-profile rails under a contract in North America – and we are very proud of this!!!

TTC tendered out the work in late 2017 as rail grinding technology alone could not keep up with the maintenance needs of the subway network in Toronto.

Work will be carried out in partnership with Rhomberg-Sersa using LINSINGER milling technology from Austria.

Rail milling can restore the rail to an "as-new condition", eliminating all defects and creating a high precision longitudinal and transversal (target) profile with lowest surface roughness in as much as one pass.

In addition, rail milling is a spark and dust free process (“shaving/planing” compared to abrasive grinding) eliminating the risk of fire as well as environmental contamination. This is a huge benefit in tunnels, urban areas and wooded, dry rural areas.

The milling unit from Austria has already arrived in Toronto. After an initial testing phase, the milling work is planned to start this year.
