Hydraulic Timing Device (HTD) Overview

Enidine’s Hydraulic Timing Device offers an innovative alternative to conventional retarders with unmatched performance and cost advantages for both retrofit and OEM applications. After extensive development with Class I railroads and frog manufacturers, Enidine’s HTD answers the need for a consistently effective retarding system for slowing down the return of the wing rail on spring frogs.

Construction and Operation

Enidine’s HTD features a completely sealed design that requires no oil refill, no maintenance, and longer service life. The improved professional seal design also eliminates environmental contamination and clean-up problems associated with oil leakage from conventional retarding systems. The lightweight HTD is designed to fit into existing retarder brackets for easy replacement or retrofit. The HTD is available as a complete kit for fast, easy installation.
