A bumping post assembly for securing to rails of a railroad track, the assembly having a frame supporting a bumper member positioned for engagement by a railroad vehicle on the rails,
- a box-forming coupling foot for coupling the frame to a railroad rail,
- the foot comprising a top member and two laterally spaced side members,
- the side members extending downwardly from the top member to define a channelway under the top member and between the side members opening downwardly and adapted to receive a rail under the top member with one side member on each side of the rail and each side member extending downwardly beyond the rail,
- a removable bottom member extending under the rail from one side member to the other side member and coupled to each of the side members to limit relative movement of the bottom member downwardly away from the top member,
- the bottom member removably coupled to the side members for removal by movement in a generally horizontal direction,
- a wedge member for wedging insertion between the top member and a rail received thereunder to wedge the rail vertically between the top member and the bottom member when the bottom member extends under the rail between the side members to enclose the channelway.
