A woman who drove on to a railway line after following directions from her satellite navigation system will not face prosecution, British Transport Police (BTP) said.
The 52-year-old, from Dorking, Surrey, was waiting at a level crossing at Norman's Bay, near Eastbourne, East Sussex, on January 16 when the device told her to turn left.
She drove her silver Ford Fiesta on to the track at 7.30pm, blocking train services between Brighton and Hastings, a BTP spokeswoman said.
The unnamed woman was investigated for obstructing the railway and driving without due care, but police decided that pursuing a case against her would not be in the public interest.
Pc Christine Holyoake, from Brighton BTP, said: "We have looked into the matter, including inquiries into any fault with the sat-nav device and have come to the conclusion that there was no fault and that taking into consideration that it was dark when the incident occurred, that the woman had made a bad but honest mistake.
"A prosecution is not in the public interest and the matter is now closed."
