After purchase services – surfacing and grinding

Tram rails are exposed to extreme loads, which will sooner or later result in some kind of defect. The repair of tram rails belongs among those jobs which are very demanding in relation to precision as well as to precise planning, due to the necessity of rerouting traffic. Our company has provided tram rail repair services since 1997, thus it has vast experience. References for the tram rails repaired by our company can be provided by our satisfied customers including DP Prague, DP Olomouc, DP Plzen, DP Most and Litvinov, DP Liberec, and DP Bratislava.

Grinding of corrugated rails


Rail corrugation is often an underestimated factor. Firstly, it causes an increased level of noise, which is a common and justified subject of local complaint. Aside from this it always leads to serious destruction of the entire track including the subsoil. The dynamic shock is relayed to the surrounding buildings, resulting in their subsequent static damage.



In order to deal with rail corrugation, our company possesses two grinders, each of which is capable of grinding approximately 400 m per shift. The machines work on the principle of rotating grinding drums. These machines have proven themselves in Prague over the course of many years. DP Prague runs around the clock tram transportation, and incidental exclusions are undesirable. Thanks to their design our grinding machines are suitable for use during tram operation, as clearing the rail area can be done almost instantly.



In the case of a necessity for greater performance, we are able to provide a machine that is able to grind 2,000 m of rails per shift. This machine, however, requires a tram line exclusion, even though it is able to provide a satisfying performance with tram intervals greater than 30 minutes.
