Signal Meanings

See "Cool Harper's Ferry" under the Dadpoints blog for the context of this: Several times saw signals on the railroad (B&O, CSX, whatever it is) that were red both ways. . .and I saw trains go both ways, so now I'm thoroughly confused as to what seeing red signals means. Does it mean, don't come this direction if you're a train? Or does it mean, caution as you come this way?

Whatever the case, we didn't see any major collisions during our Harper's Ferry visit today....
