EN4CER:MTU - On-board Computer

EN4CER MTUEN4CER is an in-cab advanced driver advisory solution which references track and signal data, and GPS position, to act as an in-cab signaling and alert system. It is an engineering solution to assist in mitigating the operational risks of train over-speed, and signal passed at danger (SPAD), for better train driver and network performance.

The EN4CER solution combines a 4MTU (Machine Terminal Unit) Driver Machine Interface (DMI) with an on-board computer processor; brake enforcement technology; and cameras for vision processing and deep machine learning - depending on the level of enforcement required.

The 4Tel 4MTU™ is a mobile computing solution designed for use in the harsh locomotive operating environment. It is designed to support multiple software applications and share resources (e.g. location determination, data storage, communications) with other on-board systems, and also back to the remote control centre.

This above rail solution is designed to empower the train driver with an intuitive technology solution to make safer and accurate decisions according to the trains location and capacity. The EN4CER system calculates the real-time information needed for speed, breaking distance, and for driver vigilance. The EN4CER solution is able to do this because the database includes the train configuration; below rail configuration; Driver interface configuration; EN4CER over-speed and SPAD Business rules; and, EN4CER Data transmission rules.

The EN4CER™ solution:

  • Monitors train performance against the authorised track speeds
  • Warns the driver of an impending over-speed occurrence
  • Initiates a brake application to bring the train to a stop, if the driver fails to bring the train under control. This is only if necessary, and according to business parameters.
  • Assists the driver to ‘call’ the aspect of the approaching signal, and if necessary initiating a train brake application to stop the train in accordance with business parameters.
  • EN4CER™ is a driver advisory and protection system, not a control system. It is designed to protect the train when the train driver fails to respond to a visual and audible prompt from the 4MTU™. Under normal operating conditions, EN4CER™ should never have to take control of the train by applying the brakes.
    EN4CER™ is designed to be used in locomotives operating on rail corridors that are controlled using either/or both, Train Order Working (TOW), or Rail Vehicle Detection Systems (RVDS).
