Abstract
A bi-directional derail is provided with an improved construction which reduces the thrust load imparted by a rail vehicle wheel against the derail, while maintaining the weight and material cost of the derail within practical limits. In a preferred embodiment, the derail is provided with a derail shoe having deflector bars which are reinforced with deflector rail support flanges for increased strength and which have an extended length and gradual deflection angle, preferably no more than 15 degrees from the longitudinal axis of the rail.
