The Moscow metro is set to lose one of its greatest features: the legion of dour Russian pensioners guarding the transport system's escalators.

Barricaded in a small perspex box and armed with a microphone, the attendants are charged with ensuring unruly passengers follow the metro's many rules and regulations.

Daily tasks include terrorizing tired commuters who sit on the escalator steps or issuing passive-aggressive reminders on correct passenger flow.

They also control the escalators' emergency stop button.

From April 1, 2017, the attendants' role will be given to members of the metro's escalator repair team, who will guard the staircases in between call-outs.

Some of the those affected by the changes will be moved to other positions. Others will lose their jobs, Russia's Life news site reported.
