High-speed, Japanese-built Javelin trains running between Kent and London in the UK are been modified after they experienced some sideways movement.
Rail operator Southeastern said the sideways movement was experienced on some trains travelling on parts of the High Speed One route between London and Folkestone.
Southeastern said the movements pose no safety risk and no trains have been taken out of service for the modifications, which are being done as part of routine maintenance checks.
Ten of the fleet's 29 trains have been modified and the modification programme will be completed in a few months, according to BBC News.
