SD Series sliding derail (single-end) set up on track

LOW-PROFILE DERAIL DESIGN

SD 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. The SD-3L is a single-end derail.

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: Nolan’s sliding derails come in two sizes, SD-3 and SD-4, which cover rail sizes 80 lb to 141 lb.
Easy Installation: The derails’ horizontal base plate is integrated with the derail housing, and this ensures a perfectly aligned derail, eliminating 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.
