Modern railroad signal practices are built on the basic concept of the track circuit. This fundamental concept has served as a basis for over a century of technological evolution, yet, certain disadvantages remain, even when the latest equipment is utilized.

Axle counting systems offer an alternative to the traditional track circuit. Unlike the basic technology of a century or more ago, axle counting offers a high level of safety without the disadvantages of variable shunting sensitivity, electromagnetic interference, lightning ingress, or frequency incompatibility.

By creating a virtual track circuit using a vital axle counting system, a signal system can operate reliably under an extreme range of environmental and operational conditions. Whether a railroad environment is affected by rusty rail, contaminated ballast, poor track and structural conditions, or storm water intrusion in the gauge of the track, an axle counting system will continue to operate reliably.

Only Pintsch North America offers the high level of reliability combined with the ability to custom design and manufacture unique signal solutions needed for the rail industry.
