Recently I posted pics of this facilty taken from a bus doing 60 on the Mass Pike (I90). It is located wedged between the Charles River and Alston MA, (part of Boston). Here are pics taken from or near the Cambridge Street Bridge: I Obeyed the "Stop" sign and went no farther: Best over all view as I had to shoot through a chain link fence: Center Beam Flats with the John Handcock Tower, (left), and Prudential Tower (center):
Tank car wedged between center beams: My favorite pic because I run what I call a "Zebra" train of solid black, white / black saddle and solid white tank cars: I like this one because of the track work:
... as long as you're here, I'll piggyback and show some yard pics too... Dayton, OH, Needmore yard. Dayton, OH, Springboro yard.
Dom, the rail guards are part of the frog casting. If you look closely you will see raised metal either side of the frog slots that restrict wheel movement from picking the wrong frog slot. This type of frog is used only in areas where speed is extremely slow such as yards or industrial sidings. The description associated with this photo from http://en.wikipedia.org/wiki/Railroad_switch...... "A one-piece cast frog. The shiny line crosses the rusty line. This North American "self-guarding cast manganese" frog without guard rails has raised flanges on the frog, bearing on the face of the wheel as it passes through the frog."
A sharp eye will also notice the manganese switch point protectors at Springboro and Needmore but the lack of point protectors at Beacon Park. They work pretty well, but will derail a hi-rail pickup if you don't hit them right (yes, I know this from experience).
