A police helicopter had to be sent to Hillington after two youths were seen lying on the tracks near the train station.
A train driver on the line heading to Glasgow Central believed he had hit the youths and phoned emergency services.
The search fortunately showed that they had not been hit.
British Transport Police is now urging parents and carers to warn children and young people of the dangers of trespassing after several incidents in Scotland.
In separate incidents children were spotted trespassing near Paisley Gilmour Street Station and in Falkirk Grahamston Station children were spotted standing on a bridge trying to touch the overhead wires.
Head of Operations for BTP in Scotland Superintendent David Marshall said: “This type of behaviour is incredibly dangerous. Trains travel at high speeds, have a long stopping distance and they cannot swerve out of the way.
“Some of the railway is also electrified, meaning overhead power lines are installed which carry 25,000 volts. Coming into contact with this equipment or being hit by a train would have life changing consequences, cause devastating injuries and can be fatal.
“It’s extremely concerning that there have been these incidents over the weekend. Too many times we have seen the tragic consequences of children ignoring the warnings and taking risks that have resulted in terrible injuries or death.
“Due to Covid we are unable to visit schools, so I strongly urge parents and carers to check where their children are going and remind them of the extreme dangers posed by the railway.”
Mark Henderson, Network Rail senior community engagement manager, added: “Trespassing on the railway can result in life-changing or even fatal injuries. We work closely with the British Transport Police to educate local communities about the dangers on the railway and would urge the public to keep off the tracks.”
Anyone who spots someone trespassing is asked to get in touch with BTP by texting 61016 or calling 0800 40 50 40. Always ring 999 in an emergency.
