Save the pics to your desktop and then you can zoom in.  They are detailed. and very clear.   On my screen I can see the bridge design.   Right at the two loaded hoppers just off the chord section was a turnout.  It was double tracked at one point.  The rails run on top of the girders. Up to the three empty hoppers it is a deck girder.  You can see the abutment where the deck stops.   About every ten feet an I beam That crossed.  that tied the tops together.  and was the only interior structure needed so loads can drop through.  The girders are 60 foot long to pier centers. This is not where the waste is dumped.  That was hauled over to the east plant and the pile over there.  This is the inbound materials.  Not one half is a darker material.  that is coal.  the lighter is Ore.   Not difficult to build from micro engineering girders.

 

 

Wow Shane! Thanks for the details! I'd love to hear more about the operation side of things. Also, I am amazed that you were able to decipher that information from those pictures. I can hardly see the girders, not to mention the I-beams! You have good eyesight lol

Matt. Multiple shots from different era's and different angles. Is how I got the info.   Plus just doing infrastructure work mostly bridge work and having access to information that helps decipher stuff like that.  I am on a bridge now where the girders are of similar dimens to the ones in the pic.   Next time I go up between the beams I will take a shot to give an idea of what the inside looks like from between the beams.   Minus the crossing i beams since road bridges don't have those relieing on the deck to do thier job.  There are x brace members though

Althought this being a road bridge the girders are identicle.  The horizontal I beam make it double size and about every 10 feet.   Oh and the highway deck pans wouldnt be there.

But somewhere I still have a 40 or 50 page document showing the ca 1930 track plans for the east and west plants... I just haven't seen them in 20 years. If I can find them, or even remember where I got them, I'll get them scanned and uploaded for sharing. -Jason

 

Wow Jason! If you have track plans for the NJZ plants that would complete my life's work Wink I hope you can find them! Keep us posted. Do you remember the name of that document with the track plans? Maybe it's available on Ebay or something...

Thanks!
