ABOUT US 

Dolnośląskie Przedsiębiorstwo Napraw Infrastruktury Komunikacyjnej DOLKOM sp. z o.o., with its registered office in Wrocław (DOLKOM), specialises in railway track superstructure repairs, including major repairs and the ongoing maintenance of tracks and turnouts on railway lines and at railway stations. In recent years, the company has also carried out revitalisation works improving the condition of railway infrastructure.

At the company’s organisational unit, the Machine Repair Plant, we repair our own machines and track-work equipment and provide repair services to PKP Group companies, as well as to external entities.

HISTORY

DOLKOM continues the tradition of PKP plants which, since 1954, have carried out railway track superstructure repairs using mechanised methods. The first such plant was the Road Branch of Mechanised Works in Wrocław, established on 1 April 1954.

The first machines used by the Branch were SBT manual gantry cranes for laying tracks and PD 90 track tamping machines. A breakthrough in the Branch’s history came with the delivery of high-performance machines for track works. The first machines purchased were the OT 400A ballast cleaning machine no. 19 and SLC track tamping machines nos. 819 and 838.

In the 1970s and 1980s, further OT 400 ballast cleaning machines and new-type MD tamping machines were put into operation. The range of machines was expanded to include USP-type track profiling machines, PLM and UNIMAT turnout tamping machines, a CSM track tamping machine, a DGS dynamic stabiliser and PŁT trackbed shoulder profiling machineballast shoulder profiling machines. These were modern machines of a high technical standard, ensuring high work efficiency.

As of 1 September 2001, the plant was transformed into a company operating under the name Dolnośląskie Przedsiębiorstwo Napraw Infrastruktury Komunikacyjnej DOLKOM (Lower Silesian Transport Infrastructure Repair Company DOLKOM). Since 2006, the company has had its current organisational structure, comprising five Infrastructure Repair Sections, an Equipment and Transport Section and a Machine Repair Plant.

In accordance with the requirements of the Act on railway transport, DOLKOM holds a railway undertaking’s safety certificate and a certificate for an entity in charge of maintenance.

The company also uses state-of-the-art track-work machinery, including the UNIMAT 09-32/4S Dynamic universal track and turnout tamping machine, the RM 80 UHR ballast cleaning machine, USP 2000 C2 ballast ploughs, MFS 120, MFS 100 and TMS 40.01 bulk material transporters, as well as 09-32 CSM and UNIMAT 08-4x4/4S tamping machines equipped with ALC automatic work process control computers and DRP electronic recorders.

The company has obtained the following Certificates of Competence for Contractors Carrying Out Maintenance Works on Railway Vehicles:

• from PKP Polskie Linie Kolejowe S.A. (extension of the existing certificate);
• from PKP Energetyka S.A. (new certificate).
