Wabtec Products Auto Ground Protection Relay Reset (AGPRR)

Automatic Ground Protection Relay Reset (AGPRR)

The Automatic Ground Protection Relay Reset or AGPRR, is designed to provide an automatic means of resetting a locomotive Ground Protection Relay (GPR) under temporary fault conditions, and to lock the GPR out when the fault is of a more permanent nature and might be potentially damaging to the locomotive electrical system. The device is designed for protection against electrical transients, and for stability under wide operational temperature ranges and input voltages.

Wabtec Corp Freight Products Axle Alternator

Axle Alternator

The Bach-Simpson™ Axle Alternator is designed to translate the rotational speed of a locomotive or transit vehicle wheel and axle into an electrical signal, which represents the linear ground speed of the conveyance. The Axle Alternator is mounted on the locomotive or car truck journal box by means of an adapter and is driven by the axle through a flexible connector or pegbar. The signal produced can be used by speed-actuated devices such as locomotive speed indicators, speed recorders and transition controls.

Wabtec Locomotive Products Doppler Speed Sensor

Doppler Speed Sensor

Bach-Simpson's™ Doppler Speed Sensor is a reliable and field service proven system with no moving parts. With no connection to the vehicle axle, there is no need for wheel size adjustments to produce a true ground speed signal. The sensor is mounted and wired independently from the truck to simplify routine truck maintenance tasks. Its ease of application and operational features make this speed sensing system second to none. The sensor is mounted under the vehicle and determines the vehicle speed via a low power microwave signal. This signal is processed to provide an accurate, true ground speed reading. The Doppler Speed Sensor's output is compatible with existing speed indicators and event recorders, making it part of a cost effective system.

Wabtec Corporation Locomotive Transit Model 7 Speed Verifier

Model 7 Speed Verifier

The Model 7 Verifier is a portable unit that provides a quick, accurate and foolproof means of checking and calibrating the operation of speed-dependent equipment, such as speed indicators, event recorders, transition controllers etc. Following a simple menu driven display, the proper functioning of a speed-dependent system can be “verified” throughout its complete range of operation. The Model 7 Verifier is programmable for nearly all-possible signal input configurations. In addition, various cable assemblies allow for connection to most speed-dependent terminations, including being compatible with previous Model 6 “Barco” units.
At Bach-Simpson™, we offer State-of-the-art products combined with dependable customer service and customized engineering support.
Remember, when you buy Bach-Simpson™, you buy experience, quality and dependability.

westinghouse air brake tech locomotive products Odometer


The odometer is a non-resettable, electronic device to count and display the total number of miles accumulated (in either direction) by the vehicle. The odometer registers miles to the nearest mile and has eight digits. The odometer receives an electrical signal from a passive speed sensor. The number of teeth on the sensing gear determines the number of pulses per revolution (PPR). The pulse count is accumulated to determine the number of wheel revolutions. The average wheel diameter, 34.5”, is used to calculate the distance. The distance is displayed to the nearest mile. The current input count is saved using FLASH memory to conserve the data when the system is not powered. The Odometer uses the average (or mid-worn) wheel diameter in its distance calculations. The measurement error introduced with a new wheel (maximum 36”) is compensated by the error with a worn-out wheel (33”). The net result is an accurate mileage total over the life of the sensing wheel.

Wabtec westinghouse air brake locomotive products Priority Alarm System (PAS)

Priority Alarm System (PAS)

The Bach-Simpson™ Priority Alarm System (PAS) provides a means of monitoring abnormal conditions in the cars of a passenger train that could affect human and/or equipment safety. The PAS signals train crew members when situations arise that require a high-priority response such as a fire in a car, an open door while the train is moving, dragging brake equipment or, most importantly, a call for help by a passenger in need of emergency assistance. The Priority Alarm System identifies the nature and location of an alarm in the train allowing the engineer to direct the conductor or another crewmember to investigate the trouble and take appropriate action.

It can be reviewed along with speed and other recorded data as an analysis of train operation. The Monitor is a rugged, reliable electronic device, packaged for quick installation and easy service.

Wabtec locomotive products Train Monitoring System (TMS)

Train Monitoring System (TMS)

Integrated within the platform is an Alerter or Train Monitoring System (TMS). This device ensures operator vigilance at all times. The TMS examines the engineer's control handling actions and will automatically bring the train to a stop should the engineer become incapacitated or unable to perform normal duties. The TMS system requires a train handling control action to reset an internal timer that is speed dependent. The reset signal can be any one of a number of Event Recorder input sources. When the timer period expires a visual and audible warning is given. If the operator fails to acknowledge the warning, a Penalty Brake application results.
