The line from Moscow to Arkhangelsk uses the alternating current, whereas the stretch to Vorkuta does not have electrification; therefore, all trains from Moscow in the direction of Vorkuta have to change the locomotive and stop in Konosha for about twenty minutes.
The presence of alternating current on the Moscow-Arkhangelsk line necessitates a change in locomotives for trains heading towards Vorkuta, which requires a stop in Konosha for about twenty minutes due to the lack of electrification on the Vorkuta section.
