The video shows how San Francsico's public transit agency recently replaced a large section of streetcar railbed around the intersection of 18th and Church streets, near the city's Dolores Park. The project, part of the J Church Improvement Project, was completed in a marathon stretch lasting just 56 hours. Press play to see how it was done.

I'm stunned to see those guys working right next to the thermite joiner with bare hands and bare arms.
