Diesel–Electric Passenger Locomotive Dynamic Brake Control
Abstract
This recommended practice provides a common design basis for the control and configuration of dynamic brake systems for diesel–electric passenger locomotives.
Keywords: dynamic brake, dynamic brake control, straight dynamic brake
Summary
This recommended practice details the function of diesel–electric passenger locomotive dynamic brake controls utilizing the 27-point plug, cable and receptacle, as specified in APTA PR-E-RP-017-99, “27-Point Control and Communication Trainlines for Locomotives and Locomotive-Hauled Equipment.” Wire designations and functional information for the communication of configuration, activation and braking effort signals are identified. Dynamic brake setup is described, as well as the rationale for dynamic brake setup features on diesel–electric locomotives utilizing dc traction.
