1 Diesel locomotives for future Our vision S. Mani ED, Motive Power RDSO

Microprocessor controls Upgraded power up to 3500 Ghp Fuel-efficient efficient turbochargers & other equipment (8 th notch SFC

2 The Saga of Diesel Traction began in early 60s with the acquisition of ALCo Technology Indigenization, Refinements and upgradations continue till today; Maintenance schedules periodicity upgraded considerably; Locomotives today are equipped with: Microprocessor controls Upgraded power up to 3500 Ghp Fuel-efficient efficient turbochargers & other equipment (8 th notch SFC down from 167 to 152 gms/bhphour) Automatic & improved filters; efficient heat exchangers Efficient AC-DC transmission Multi grade lubricants

Now moving swiftly towards technology upgradation.

3 WDG4, 4100 hp high-adhesion freight loco WDP4, 4100 hp 160 km/h passenger loco Consolidation Indegenisation Now moving swiftly towards technology upgradation. First step : incorporation of IGBT-drive serialized in 2007

11 Train Control & Operation thru Advanced communications Train information & Centralized control; train information in coaches Satellite Cab signalling & continuous communication between CTC and driver Auto loco propulsion through GPS-based trip optimizer GPS/GPRS + Loco Computer Main frame Anti-collision device with braking function integrated with locomotive computer Positive train control through transponders

13 (1) Via Remote Monitoring, a locomotive automatically initiates a remote alert giving an abnormal condition and sends the locomotive number, its condition and the fault(s) which triggered the condition. (2) The Central Server receives and stores the information. (3) The central Server automatically sends an Alert Notification to a predefined list of people in a predefined order, regardless of location or the locomotive management center and, if applicable. Once the alert is accepted, the person may view a brief summary of the locomotive condition included in the notification. Notification can be sent by pager, mobile telephone, or an online screen alert. (4) Locomotive Management Center personnel performs Remote Diagnosis of the locomotive by going online and accessing additional locomotive information.
