Aldon Company has introduced SaberTooth brand portable derails for wood or concrete ties. A series of seven, ½ in. tall steps or notches allow derail to fit a variety of rail sizes without any adjustment.
The notches make contact with the edge of a tie plate (wooden ties) or the edge of a concrete tie, or the rail anchor clip on concrete ties. The notches are cut at a back-angle.
This creates downward pressure to keep the derail from lifting. This makes it less likely for a notch to slip off the tie plate or edge of tie.
The tie brace terminates in a stout, sharp pointed safety hook. The derails offer tool-free installation with finger-tight pressure on four stainless steel thumb screws that secure the derail to rail.
Options include a one-way for freight cars, 4-axle and 6-axle locomotives and a two-way for freight cars and 4-axle locomotives. Units weigh 36 lb.
