Go off the rails
Meaning
To behave in an uncontrolled and irresponsible way, often leading to personal or professional failure.
Origin
The industrial revolution in the 19th century brought railways into prominence, and with them, the terrifying spectacle of a train literally "going off the rails." This literal image of a locomotive veering wildly from its intended path, plunging into chaos and destruction, provided a potent and easily understood metaphor for any person, plan, or situation that lost control, deviated from the norm, and descended into disarray or ruin. The phrase quickly caught on, becoming a vivid shorthand for a dramatic loss of control.
Examples
- After a series of personal setbacks, the once-promising artist started to go off the rails, neglecting his work and responsibilities.
- The manager worried the entire project would go off the rails if they didn't get the budget approved soon.
