Keyway Tie

US Patent 10,711,406

The keyway 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
