what does this mean in English - "switched off rail 2f out"

horse moved off the rail 2 furlong out .

The rail is electrified to prevent bunching, but is switched off 2 f out, so as not to impede tired horses that hang!. :^0

it's that situation where the jockey has got the horse into an impossible position and then, to make a show of it, he switches from the rail to the outside and so is running on at the finish, job done

Hi WR, you OK.

so are we to assume he moved off the rail to take advantage of a gap, or the jockey couldn't keep him straight?

thank you wr and st

yeahyeahwhatever, sorry mate I thought you were just having the craic, and I joined in, in that spirit, no offence intended.

no btf - I really am that clueless :-)

:^0 pretty clueless myself most of the time :D
