PD-4RT and PD-5RT Derail
Available from Nolan Company
The PD-4 Portable Derail is one of Nolan Company’s latest low-profile models. It is a single-end derail.
NEW DERAIL DESIGN -- PD-4 derails are fabricated from high-strength steel, and completely redesigned for increased effectiveness and ease of installation. Derails are manufactured using a proven design and 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). Nolan’s portable derails come in two sizes (PD-4 and PD-5), which cover all rail sizes from 70 lb. to 141 lb. Left and right models -- PD-4L and PD-4R weight 42. lbs.; PD-5L and PD5-R weight 46 lbs.
- Low Profile: The top of the derail block sits just 2-3/4” above the top of the rail head.
- Lightweight: Nolan’s portable derail weighs just 46 lbs.
- Security: The portable derail, staff, and flag can be padlocked to the rail head to ensure visibility and safety, and to prevent unauthorized removal.
- Easy Installation: Portable derails fit onto the track easily and require no special tools to install.
