If wheels only move along one axis, how do trains, carts, and subways turn around curves without derailing? The secret is beveling. Trains have single-flanged wheels: the tread against the rail is beveled, making the shape more cone-like than flat. Near to the flange, the tread has a thicker diameter than at the edge.
When a train hits a car or truck at a crossing, the train always “wins”. It is much, much larger and heavier than any truck. However, it is possible that a collision at a “grade crossing” (where a road crosses a track at track level, not an overpass or underpass) can cause a locomotive to derail.
While fatalities from train derailments are rare, derailments themselves are actually quite common.
