The signalling system modernization of the Kotka marshalling yard was successfully completed

Mipro has successfully renewed the existing signalling system at the Kotka marshalling yard. The project, which began in 2018, was completed in November 2020 and fully covered the modernization of Hovinsaari and Asema traffic locations.

The Kotka marshalling yard is a significant calling point and terminal station for passenger traffic and it serves as the marshalling yard for the freight traffic coming from the Kotka harbour. Most of the forest industry and chemical transit transports to Kotka pass through Kotka Hovinsaari, where the former VR76 relay interlocking system was replaced with the SIL4 safety integrity level interlocking system and safety equipment.

“The commissioning of the new interlocking system was carried out in November, in three different phases, to ensure the smooth flow of traffic also during the commissioning.

Overall, the implementation was successful and we are satisfied with the outcome of the Kotka marshalling yard project.” says Niika Hämäläinen, the project manager of KORP project.
