MRT 918 is used on Diesel Electric Locomotives. It can also be used for Electric Locomotives, Rail Cars and Electric Multiple Units. These Digital Tachographs are used for indication and recording of speed, time, distance, other locomotive operating parameters. This is a Microcontroller based system with high accuracy and better reliability. The system also records data of Dynamic Braking, Coasting Duration and operation of Tractive Effort limiting switch (ON/OFF) of the locomotive. Apart from these parameters, any five digital inputs can be interfaced for monitoring and recording purpose. The data is recorded in a compact credit card sized and rugged memory card, consists of State-of-Art high density flash memories, which do not require any battery for retaining the data. Also full backup of same data is maintained in the Recorder. Recorded data can be retrieved, analyzed and printed using Data Retrieval Unit, connected to a PC with data analysis software MSW 918.

For Indication in Second Driver Cab, Speed Indicator type MRT 918 Indicator is available. This is a slave unit and gets all the Information from Master. it receives Speed, Time and Distance data from the Recorder cum Indicator unit through serial communication. This data is deciphered by the micro controller and all parameters are displayed same as in Master Unit. This provides cost benefit by avoiding duplication all hardware. Data Entry Keyboard is provided for entering the Driver Settable Parameters and for viewing all the parameters.
