At least 40 pedestrians and a line of motorists have been frustrated by yet another level crossing failure in Spalding.
Just three days after similar problems caused anger disruption in the town, barriers at Winsover Road level crossing have stayed down for at least 30 minutes.
Network Rail engineers are on their way to Spalding to repair the fault and, if necessary, manually raise the barriers.
The latest problem comes after a points problem caused level crossing in London Road, Park Road and Woolram Wygate level crossings to “fail safe” or stay down for at least three hours on Tuesday morning.
A Network Rail spokesman said: ““We apologise for the disruption in the Spalding area which is due to a signalling problem which, as a a result, has caused the level crossings to come down.
“The signalling system has ‘failed safe’ which means that it thinks that a train is coming when it isn’t.
“A team of Network Rail engineers are on their way to fix the problem as soon as possible or they will manually raise the barriers to allow pedestrains and traffic to move again.
“Residents should not that when a fault is detected, the level crossing barriers ‘fail safe’ meaning the barriers are dropped to protect the public.”
