Morphology

go + off + the + rails

The sense 'to become chaotic or deviate from the expected course' follows directly from combining 'go' (move/change state) + 'off' (away from) + 'rails' (tracks representing the correct path); the spatial image of leaving the rails maps transparently onto deviating from an expected course. This spatial-to-abstract metaphor is common and predictable, so a B1 learner who knows the constituent words should be able to infer the MWE's meaning.

Etymology

Go off the rails comes from the image of a train go off its rails (tracks) and lose control. That's why when a person or plan goes off the rails it means they 'become chaotic' or 'stop following the expected course'.
