Two motorists have driven through red warning lights at a level crossing on a miniature railway in the three weeks since a fatal crash at the same spot.
The trains run on a 13 mile route between Hythe and Dungeness
Police in Kent said drivers were still ignoring the signals on the Romney, Hythe and Dymchurch Railway.
Engine driver Suzanne Martin was killed at the crossing in Dungeness Road on 10 July after her train collided with a car driven by a 20-year-old local man.
He was bailed by police pending further inquiries into the derailment.
Police said in the first incident, on Saturday 23 July, a silver mini was seen by a member of the public driving over the crossing when the warning lights were flashing.
Just over a week later, on Sunday 31 July, a car drove in front of an oncoming train.
The engine driver reported the incident to the police and the car was located and the driver spoken to by officers.
A spokeswoman for Kent Police said motorists in the area were being advised to be vigilant as the lights "were there for a reason".
