REMMLOT: PART-0

(OVERVIEW)

Specification Number MP.0.0402.04 Revision 7 Date of Issue 09/11/2020

Brief Description

This is a part of a four part specification numbered 0 through to 3 describing the requirements for setting up systems for Remote Monitoring and Management of Locomotives and Trains (REMMLOT).

FOREWORD

REMMLOT Enables remote monitoring of Diesel Locomotives. It creates a complete IT enabled ecosystem which provides a platform for remotely monitoring health and operational characteristics of diesel electric locomotives.

It also enables monitoring of performance of crew and helps in identifying lapses, e.g. when he passes a signal at danger. This will enable focused counselling and training of such crew, who are prone to unsafe working.

REMMLOT also monitors condition of locomotive and makes preventive maintenance of locomotives more effective. REMMLOT monitors shutting down of locomotives when idle for a long time and generates management information to ensure this.

The complete specification for REMMLOT is split over four parts numbered from 0 to 3. Together these parts specify the requirements for setting up the complete system.
