例文
- With the left truck wheels running just inside the rails, and the right truck wheels just outside the rails, the engine continued down the track for another 198 feet ( 61 m ) until the left front truck wheel hit a crossover frog from a trailing switch ( part of a vestigal railroad switch track for a railroad siding at the location that in 1925 no longer existed ), diverting the engine to the right and causing it to derail entirely.
