An F Line "Queens Boulevard Express" subway train has passed through the MTA's Smith-9 Streets station in Brooklyn, New York, which is the highest rapid transit station in the world. As such, this line features some impressive through truss bridges, built to accomodate the four tracks and, in the center, electrical cabling. There are several of these impressive bridges on this elevated line, including right in the Smith-9 Streets station itself (just behind the photographer). [New York NY - July 20, 2018]
