At 12:32 Moscow Standard Time (08:32 UTC) on 20 May 2014,[1] a freight train derailed between Bekasovo and Naro-Fominsk on the Moscow–Kyiv railway.

[6] It was travelling at 95 kilometres per hour (59 mph) before the driver made an emergency brake application, having seen the cloud of dust caused by the derailment of the freight train.

[10] Subsequent inquiry revealed that the end reason of the derailment was the sun kink on the seamless rail due to thermal expansion and improper maintenance.

[11] The problem with the rails was known and attempts to rectify them were made, but couldn't be completed in time before the accident, because the institutional culture discouraged the personnel from interrupting the traffic on a busy line.

[12] Additional blame was placed on the maintenance team trying to rectify this problem, which failed to notify the controllers and the train crews about track work they were conducting.
