Fri Work Of A Rail Grinding Machines
Jan 04, 2014 More than 20 standard rail profiles are in use. Even though grinding machines are designed to fit within the smallest overall clearance envelope, the wide array of in-track safety systems in use pose obstacles that make it difficult to operate the same grinding machine on multiple properties.
Each railway has specifications for rail grinding work. Apart from standard profiles, special target profiles are defined. In the case of RCF, gauge corner relief is generally specified. Grinding work can be classified as initial preservice, preventive cyclic and corrective work.

Dec 04, 2017 More productive grinding at higher speeds of up to 15mph enables increased metal removal, and an increased transit speed of up to 70mph to get around the network means fewer passengers and freight services are impacted. The machines are modular and therefore can be attached together to make a larger machine or can remain smaller to be more targeted.
Grinding Practices Earlier generation rail grinders were fitted with fixed grinding motors that required many grinding passes to remove short-pitch and short-wave corrugations, and improve rail surface conditions. Today, modern rail grinding equipment can achieve the desired rail profile and surface condition in a single pass.

Grinding trains. A grinding train maintains the track and helps to increase the lifespan of the rail. These trains remove small layers of metal from the railhead, helping us to keep the track in good condition. Our new fleet was introduced in 2017 and offers increased metal removal due to more productive grinding at speeds of up to 15mph.
Rail grinders will typically use a coarser stone to work out all of the dips and wear found along the rail head and a finer stone to finish the work and return the rail to a nice, polished finish.
