Railroad track switch operator

摘要

An improved cylinder head for a railroad track switch operator includes totally self-contained electronics and pneumatics for easy and direct replacement of a cylinder head on a prior art switch operator. The improved cylinder head has enhanced porting to improve air flow and speed of operation, a voltage control module permitting the unit to operate with either 24 volt or 12 volt line power, and recessed portions for covering or enclosing delicate and/or sensitive components for maximized protection in harsh outdoor installations.
