- Well, your article header asks one question, and the body of your
- message asks a different question. I assume from the explanation
- about a class that you want to know the longest load that can
- be carried by railway in North America.
-
- FYI, a single beam can be carried by more than one car. Several
- variations are possible, including bearing the load weight on
- one car and having idler cars on both ends to ride 'under' the
- ends of the beam sticking out. Another way is to have the load
- supported by two 'end' cars with one (or more) idler cars inbetween
- the end cars.
-
- Railroads routinely carry lengths of "continuous" rail which are
- thousands of yards long (on multiple flat cars, obviously).
-
- I'm pretty sure you could load up a beam that was a couple hundred
- feet long, but you'd have to check with AAR loading rules/techniques.
- Check with the American Association of Railroads, or with the
- freight service department of a railroad that has a customer service
- office nearby.
-
- An upper bound would be when the height of your beam to be
- self-supporting (for its length) would exceed allowable RR
- verticle clearances, or when its width/length would not
- clear side-limits on curves.
