Changes have been implemented to the way freight trains carry containers following an incident in Deeping St Nicholas.
On March 31, an empty container on a train travelling towards Spalding was blown off in winds of about 68mph. If followed a similar incident in Cumbria on March 7, with a train travelling at 75mph.
Rail operator Network Rail has completed investigations and says restrictions have been revised in light of the incidents and containers are now either mechanically secured or removed from the train completely when high winds are forecast “which will reduce the risk of a repeat incident”.
Meanwhile, operational problems with level crossing barriers on the upgraded GNGE line continue.
Mill Green and Park Road in Spalding had issues for more than an hour early on Thursday morning.
Police closed part of Woolram Wygate to prevent people trying to cross at Mill Green.
As previously reported, South Holland District Council chief executive Anna Graves wrote to Network Rail asking for assurances over the ongoing issues.
Mark Terry, managing director of the London North Eastern and East Midlands routes, replied.
A council spokesman said: “In the letter, he apologises for any inconvenience caused by the recent level crossing breakdowns and states that his team is working hard to rectify the issues.”
