US Patent 10,711,406
Engineered for flexibility and durability, the Keyway Tie offers the strength of concrete with the elasticity of wood tie trackâsimplifying replacement and maintenance.
The design uses an integrated fastening system (comprised of a ductile plate and pad) to provide the strength and gauge holding ability of concrete with the modulus of wood.
- Designed to be fully interspersed with wood ties and utlizie traditional MOW equipment
- Supports incremental conversion from wood to concrete with minimal capital impact while strengthening track and extracting full value from wood tie assets
- Accommodates different rail sections or fasteners with simple plate change
- Track guage adjustable
- Siffness can be modified for optimal track transitions and bridge applications
- Guard rail and transition ties available
