SEPTA is planning to post suicide-prevention signs at the Norristown Transportation Center on Wednesday morning, as part of Worldwide Suicide Prevention Day.

The signs, put up in partnership with Montgomery County Emergency Services Inc., will display information about and the phone number for the National Suicide Prevention Lifeline, 1-800-273-8255 (TALK).

SEPTA says about half of the fatalities that occur on the rail system are suicides. The signs are meant to remind people that help is available, 24 hours a day, seven days a week, 365 days a year.

The transit agency said it also plans to post more informational signs about the Lifeline hotline throughout the SEPTA system over the next year.

So far this year, three fatalities on the transit system have been confirmed as suicides, according to SEPTA. Last year, seven deaths were ruled suicides.
