ABSTRACT:
The strength and reliability of railroad track structures, such as frogs, crossings, and guardrails, is enhanced. Filler members and filler blocks are fitted in to support and strengthen the structures. The filler members and filler blocks provide better matching and alignment of load transfer surfaces. The track structures with the improved components are more easy to align and assemble. The strength of the assembled track and structures is also increased, and the structures are more easily maintained.
