Let the train take the strain.

A compact piece of proverbial advice: don’t carry burdens you can offload to a system designed to bear them. “Train” suggests a powerful, steady mechanism that runs on tracks—an image of infrastructure, routine, or delegated support—while “strain” evokes personal stress and overexertion. The line implies that efficiency and well-being come from letting established processes, tools, or collective arrangements do the heavy lifting, rather than relying on individual effort alone. It can be read as counsel about work (use proper equipment and procedures), travel (trust the timetable), or life generally (accept help and structure). The rhyme makes it memorable, like a slogan or maxim.
