The great locomotive race
When I was coming in to work this morning, the #70 bus passed the north end of Brooklyn Yard at exactly the same time as a northbound Yellow Menace freight. I had about 15 seconds to pull the pentax out of my purse and get a couple of pictures through the (exceptionally dirty) side window of the bus before the #70 turned onto Powell and diverged from the SPYellow Menace mainline.
It was not nearly as gloomy as this picture would seem to indicate. The high-floor busses that hold down route 70 have unbelievably filthy side windows, so this picture is taken through a thick layer of glass and an equally thick layer of road grime and caked on exhaust precipitate.
