According to LNER, in the past 12 months its staff had found a total of 126 people who were missing and they had referred more than 500 people for support from social services, mental health teams or charities.
The company said safeguarding had become a priority for the whole rail service in recent years.
Jim Rawcliffe, LNER’s security and emergency planning manager, said: “We train our staff to look out for anyone who might be distressed, concerned, or just not look at ease with the surroundings.”
The training was “all about encouraging that member of staff to go and speak to the person”.
“It’s just trusting your gut feeling that something isn’t right and doing something about it,” he added.
