The railway in operates on single phase AC at a 25 . The railway has its own traction current lines with an operating voltage of 27 kV. These lines are mounted on the pylons of the overhead wire over the catenary wire. In , single conductors are usually used for traction current lines but, f. .
Traction current converter plants are either decentralized (where one plant directly supplies the or of the traction system, with no feed into a traction current distribution network) or centralized (for the supply of the , usually in addition to the direct supply of the overhead lines or third rail). Central traction current converter plants are generally found in (primarily in the cities of
