Photos of railroad workers replacing a Muni light rail track section on Duboce street, Church street and Market street (San Francisco).­

Each section of track work, such as replacement of the double diamond crossing structure at Church st and Market st, takes 2 or 3 days with crews working 24h during week-ends.­

The work was realized by local contractor NTK Construction.

I must thank NTK management and crew for letting me shoot those amazing photos on their construction site.­
