A control system receives signals representing a presence and position of a secondary movement system onboard a vehicle. The secondary movement system changes movement of the vehicle without generating thrust or propulsion to move the vehicle. The control system creates a schedule of use of the secondary movement system based on the presence and position of the secondary movement system and controls the secondary movement system based on the schedule that is created.

Described herein is a system for testing one or more multiple-unit (MU) conductors on a locomotive using a first and second test unit together with a portable display unit having a wireless transceiver for communicating with the test units. The portable display may include a panel of LED indicators corresponding to the MU conductors to be tested and a user interface in the form of a display screen. The system may be used for running both test procedures and monitoring procedures. The wireless portable display unit allows a single technician to run the procedures and review information from both test units without using long and heavy MU jumper cables.

A control device for a railway vehicle includes a housing and a cover covering an opening. The housing is provided with a pair of first members. The cover is provided with a second member having a plate shape. The contact of an edge of a hole portion of the second member with the vertically lower bottoms of edges of notch portions of the pair of first members causes the second member to be supported by the first members so as to be rotatable about a rotational axis. The contact of edges of the hole portion with the pair of first members restricts displacement of the second member.
