TPX Mode

Automated plate handling system that mechanically secures the plate to the rail during wood tie exchange

Tie Only Mode

Allows machine operation with plate handling system stored for increased versatility with wood ties near switches, crossings, and certain operating conditions

Adjustable gripper force

The gripper force for the tie gripper assembly can be adjusted for the following:

  • Tie degradation (to prevent further tie disintegration during removal)
  • Tie insertion (to prevent damage to new ties)

Operates from either side of track

82-inch-stroke-length workheads allow the operator to perform removal/insertions from either side of the track, allowing greater control in obstructed or constricted areas; the operator can also access the cab from either side of the machine.

Adjusts for different rail types and heights

Simple switch settings allow the operator to quickly adjust for jointed or welded rail. In addition, operator-controlled settings allow rail lift height adjustments for different rail heights - even different heights on left and right rails.

Stock fewer maintenance parts

TPX uses many of the same components as other Nordco machines, you can stock fewer maintenance parts in your trailers
