A park activity special to Torrance will soon be celebrating a milestone.

The Southern California Live Steamers will celebrate its 75th birthday and its 500,000th rider this Sunday during their ride from 11 a.m. to 3 p.m. at Wilson Park. The non-profit organization offers free rides to people on their mini railroad track. Their mission is to celebrate the rich history of railroads in the city of Torrance.

Also this weekend, you can sign up for their 75th Anniversary Excursion that will help the organization raise money to be used toward buying a new engine that they hope will carry the next 500,000 riders.

They are located at 2290 Washington Avenue.
