Abstract
A railway tie insertion system includes a guide plate having an easily adjustable height, and in many embodiments including a pair of side guides. The tie plate extends for substantially the entire distance between the rails, thereby minimizing the escape of ballast. During insertion of a tie, the tie guide plate and associated side guides provide guide surfaces along three sides of the inserted tie, thereby ensuring that the tie is inserted perpendicular to the pair of rails.
