Railroad spur detail
Railroad spur detail
(OP)
I have an industrial facility that will have a railroad spur come into the building. The rail will be integral with the slab on ground, ie. slab butts up to rails, fork traffic over rails, etc. Are there details someone can share with me that shows how the rails and the slab on ground inter-relate, perhaps sub base detaisl, etc. I you don't have this, are you aware of any publications discussing this?
Thanks.
Thanks.

This publication is one I can think of that may contain suggested design methods for approach slabs.

AREMA has a publications section you may browse.
Internet seems to have more information on bridge approach slabs, but not many hits on train approach into the building.

1. The trains are moving a very slow speeds (assume that this would apply in your application, also). As differential settlement occurs over time, it is very easy to detect that a problem is developing without increased danger of a "train wreck".
2. The "lifting" of tracks/ballast (on the traditional railroad bed) to correct vertical alignment is routine for the railroad maintenance crews.
The key to the success of this approach at an industrial facility is to have a responsible maintenance superintendent, who is aware of what to look for. Electric generating stations have such individuals - the coal handling system is of vital importance (no coal - no electricity).
Since railway lines need routine inspection & maintenance for numerous other reasons, suggest that the "Keep It Simple" principle is worth consideration.

Thanks for your insight!
RE: Railroad spur detail
However the railway lines leading both to and from the pit are on "everyday" railroad bed and ballast - all the way right up to the edge of the concrete pit walls. Of course this means that this approach track & its bedding can (and do) settle. This is the type transition that I assume you are asking about. If so, in my experience, the differential settlement between the soil supported track and the concrete pit supported track is not a problem, for the reasons discussed above.
Hope this helps,
Best Wishes

My condition will be a slab on ground with fork traffic loading rail cars with plywood type sheathing. The slab will be built around the rails. The construction would probably be simialr to a roadway rail crossing with a concrete approach slab.
