Question

what does this mean?

never say i cant

i think

Answer 2

Cant is the angle the track is tilted, so that one rail is higher than the other. The sign is prohibiting changing that angle.

Answer 3

Cant angle. It's another term used for the slant on a rail, but also on a raod. Mostly for a railroad though. It's when one rail (of the normal two rails) is higher than the other, to make safer and more efficient.

Like on a road, going around a a sharp turn, mostly on a highway, the road is on a slant. Mostly on a commuter train (non freight) The angle can be changed. Depending on which way a train is coming on. Your sign, the one you saw, just means, it can't be changed, for what ever reason.
