"The preliminary reason for the derailment is the break of the pantograph of the previously followed electric train of OJSC TsPPK, followed by a run over this part on the tracks," the message says.
The incident occurred at 21:04 at the Tolstopaltsevo station during the departure of the Moscow - Maloyaroslavets train.
The first and partially the second train cars went off the rails.
Nobody was hurt, the passengers were evacuated.
According to the Ministry of Railways, compensation buses have been assigned for transportation on the Tolstopaltsevo - Lesnoy Gorodok - Aprelevka section.
For the period of restoration work, the movement of trains is organized along a shortened route.
