underground supports with steel
Posted by jlcjrbal on Thursday, November 15, 2007 8:52 PM
I hope I can explane this... I have had this photo for along time of a town on top and a trains under it. there is a waiting area for passengers but what I like most is the open steel look.. I have tried to post the photo on line but it just does not take it  I would happily email it to anyone who may have a clue of what I am talking about

In order to post photos on this forum, you need to upload your photo to a 3rd party photo-hosting site (eg: photobucket), then follow the instructions found here... http://www.trains.com/trccs/forums/899776/ShowPost.aspx

Sounds very much like what Mister Beasley has done with his subway stations.  You might try entering a forum query on 'subway' to see what comes up.  He had several good photos.

This may be the kind of thing you're describing.  (This shot is intentionally a bit dark.  I wanted to get the newly-installed subway station lighting to show up.  Click on the pictures for a bigger view.)

This is the same station from above, with the street-level scenery removed:

This shows the steel girder effect I was trying to get:

The girders are Evergreen H-girder pieces.  I used a piece of u-channel for the top horizontal supports.  The u-channel is cut from some scrap pieces that are throw-aways from the coffee machine packets at work.  I typically cut and assemble the steelwork before painting, and then I spray them gloss black from a cheap rattle-can.

If you notice in the picture the individual who built it uses the structural members for show and has some "concrete support" in the form of pillars.  I suspect they are wrapped wood to support the roof area.  If I were going to do that and not knowing what is above I would want to maximize the strength of the roof so it doesn't sag while minimizing the weight of it.  Two ways come to mind and both involve the same kind of construction.  I would make the roof a box beam which in essence is  similar to an I beam.  Most people don't know that a box beam made of 1 x 4 boards is stronger than a 4 x 4 of the same dimensions.   So I would use some 1/4" plywood for the top and bottom skin with 1/4" spacers to make the roof.  I would glue and screw that together and then cover with styrene to form the steel work.  Alternately I would use a sheet of styrene for the top and bottom and use something like Plastruct I beams for the internal stiffeners. Don't forget to completely detail the interior before adding the roof or come up with a way to lift it off for servicing the tracks.

This is a wider shot of one of my stations:

As ndbprr pointed out, the girders and "metalwork" don't actually provide any support.  In this picture, you can see the chunks of 1x2 wood which I've hidden inside the "tile" walls.  The tile is a hydrocal casting, which I bent around a piece of 1x2 when the plaster had set up but didn't quite harden yet.

The roof of this station is a piece of quarter-inch masonite.  It rests on the wood blocks, which carry the load down to the foam base.  The plastic girders are all just for show, although they do hold up the interior lighting.

The steel supports in the photo are sold by Central Valley.

Sorry, ndbprr, but a solid 4x4 is stronger than a box beam of the same size and material.  Please check the structural formulas to verify.  (The box beam is relatively strong for its weight, but not stronger than the solid member.)
