A rerailer is a tool or piece of equipment used to help guide a derailed train back onto the tracks. It is typically placed under the wheels of the derailed train to lift and position the wheels correctly, allowing the train to be safely moved back onto the track. Rerailers can be manual or mechanical, and they are an essential tool for railway crews in case of derailments. Their use helps reduce the time and effort needed to get the train back on the tracks and allows train services to resume more quickly after an incident.
