832.25 track-kilometres of the traction network

Between January this year, the workers of PKP Energetyka S.A. were de-icing the traction network, repairing burnt conductors and removing fallen trees from the tracks.

PKP Energetyka S.A. summarised the action as follows:
- 832.26 track-kilometres of the traction network de-iced  (over 550 track-kilometres on main lines) – twice the original estimates
- 13 MV lines (137.4 km) damaged
- 145 HV poles broken
- 100 insulators damaged
- 18 traction substations cut off from the power supply (15 of them were not supplied by external suppliers)
- 300 workers of PKP Energetyka S.A. and 24 maintenance trains working

Estimated costs incurred by PKP Energetyka S.A. only in the abovementioned period amount to approx. PLN 2,150,000.

Various de-icing methods were adopted, among others, the mechanical de-icer. The method was effective solely for ice layers not exceeding 10 mm. This is why this solution was used to de-ice approx. 8% of the traction network (62 track-kilometres). The practice proved hand de-icing to be the most efficient method. One maintenance train de-iced the traction network at the rate of approx. 1 track-kilometre per hour.

This weather anomaly, which occurs once in decades, took the form of intense rain falling at -3 degrees Celsius, freezing instantly on everything, including the traction network. This resulted in ice coating, 10 to 30 mm thick, preventing the operation of electric trains (locomotives).
