If the question is what is the longest wagon which can circumnavigate a
closed loop of track without derailing, the answer is probably at least
100 studs. Such a wagon can only navigate a circle of track. See this
picture:

for an idea... Note that you can make the wagon quite a bit longer,
limited only by the rigidity of the cantilever you use to extend the
length.
If you mean in a multi-car train, and capable of navigating points and
other "normal" track configurations, not much more than 40 studs I would
tend to think (though I think folks do have some cars in the 60 stud
range). The main thing which will get you is S-curves, though the
overhang over the trucks will get you (however, if you articulate the
multicar train at the same point that the trucks attach, and design your
articulation to be able to take a very acute angle, you should be able
to get up to like 80 stud (the circle radius) cars to negotiate at least
an oval, though you would have to run the train pretty slow (you will
have some severe differential speed effects as a car enters a curve,
where it's front wheels will be traveling at a different linear speed
than the rear wheels.
I bet you could get a pretty long train though if you ran a "jiggered"
circle, it should be possible to create a very large circle using just
straight track, by not perfectly butting the track sections together.
The resulting large radius could handle pretty long cars.
