The 373 Series E-BELL is a solid-state electronic bell with a sound that is just like a pneumatic bell. It does this without the normal maintenance and/or potential freeze ups of conventional bell ringers. The design is half the weight of a cast iron pneumatic bell and just as rugged. A dual interface bracket makes it possible to retrofit GM and GETS locomotives with ease. Two models are available to choose from, which include a hardwired model (373-010), and a 2-pin connector model (373-011).
