Rail Accident Investigation Branch

One of the men had to be treated in hospital after being freed by the emergency services on 15 March.

A train sped through a Grantham junction on 25 February leaving staff onboard with minor injuries.

Investigators, who also criticise Network Rail, say the operator forgot to lower a crossing barrier.

The workers moved clear of the approaching train's path with two seconds to spare, a report states.

The pedestrian died after being hit by a train travelling at nearly 100mph, inspectors say.

Investigators say they are examining all circumstances surrounding the incident in south London.

The train was carrying 100 passengers when it derailed in March 2024 following maintenance work.

Investigators say the temporary pipe, installed in 2016, was damaged days before the derailment.
