Abstract
A vibration dampening boot for railway tie blocks and a method of manufacturing railway tie block assemblies. The boot includes a bottom wall with resilient tie block contact structures disposed at different heights for initial tie block support and variable vibration dampening. The upper portion of the boot terminates in a removable wall connected to the side walls of the boot by a relatively thin tear strip to enable direct pouring of cast material, such as concrete or epoxy, into the boot for casting the tie block, with the wall removable after installation of the tie block assembly into a railway bed. In this manner, the boot may be used with pre-cast tie blocks as well as accommodate direct casting of the tie blocks within the boot to form a tie block assembly.
