Derhachi: 110 kV traction substation hit

On October 7, 2026, Russian forces struck the "Derhachi" traction substation in Kharkov Oblast. The attack damaged a 110 kV power transformer, causing oil system depressurization, leakage, and fire covering approximately 100 m².

The strike eliminated the primary power channel, destroying normal redundancy after previous damage to backup units. The transformer is now physically destroyed and requires removal from service for repair or replacement.

Train movement continues via redistribution of power through neighboring substations and contact network sectionalization. However, the node operates in a significantly more vulnerable configuration without normal reserves.
