Morphology
The phrase is a straightforward simile using the common comparative pattern 'as X as Y' where 'skinny' (very thin) is being likened to a 'rail'—a long, thin bar—so the intensified meaning 'extremely thin' is directly inferable from the parts. This compositional pattern is cross-linguistically common and thus should be understandable to a B1 learner who knows the constituent words.
Etymology
The phrase skinny as a rail may come from the picture of a long, thin metal rail on train tracks. Saying someone is skinny like a rail makes it easy to see they are very thin, so the phrase means 'extremely thin'.
