Hinged Derails

Nolan Hinged Derail (Single End)
The photo shows a HD Series single-end derail set up with a HDF staff assembly and a BF-2D DERAIL flag. Staff assemblies and flags are sold separately.

LOW-PROFILE DERAIL DESIGN

HD Series derails are fabricated from tough carbon steel, and are produced using a proven design featuring a lower height above the rail head. They will derail all rolling stock including mainline locomotives when installed and used properly (maximum speed is 10 mph).

BENEFITS

  • Longer Design: A longer derail block allows for a decreased deflection angle, which increases the functionality of the derail.
  • Low Profile: The top of the derail block sits just 2-3/4” above the top of the rail head.
  • Flexibility: Hinged derails (both single-end and double-end) come in two sizes, which cover rail sizes 70 lb to 141 lb.
  • Easy Installation: The derails’ horizontal base plate is integrated with the derail housing, which ensures a perfectly aligned derail, and eliminates adzing and shimming of the ties. This unique base design requires no tie strapping or rail braces on the field side of the rails. The derail becomes a fixed part of the track.
