Abstract

A remote control unit for controlling a locomotive is provided. The remote control unit includes a manually operable control device, a brake setting display and a display controller. The control device allows an operator to select a level of brake application. The brake setting display includes an array of discrete display elements. The display controller actuates a first display element when a first level of brake application is selected on the control device. The display controller actuates a second display element adjacent to the first display element when a third level of brake application is selected on the control device. The display controller actuates the first and that second display elements of the array when a second level of brake application that is intermediate to the first and third levels of brake application is selected on the control device. Alternatively, the remote control unit includes manually operable control devices, a setting displays and display controllers for controlling and displaying speed or throttle settings in a similar fashion as that of the brake setting.
