INDIAN GEOGRAPHY

Detailed explanation-1: -Diesel–electric locomotives (two examples are shown in Fig. 9.36) are in widespread use around the world. They have also been impacted by the availability of IGBTs with high power ratings. In these trains, diesel fuel is used to generate electricity.

Detailed explanation-2: -Freight and passenger rail rely almost exclusively on diesel power. The latest diesel innovations contribute to cleaner air and reaching climate goals. According to the Association of American Railroads, in a typical year, US freight railroads move around 1.7 billion tons across nearly 140, 000-miles of track.

Detailed explanation-3: -In India, which has the world’s third largest railway network, 37% of the trains are pulled by diesel locomotives, Vaishnaw had told Rajya Sabha in December 2021. That’s roughly 5, 000 trains a day. Indian Railways used 2. 3 billion litres of diesel to haul trains in FY 2019-20 – almost 6.

Detailed explanation-4: -A shift from steam engines to diesel and electric engines has increased carrying capacity of the Indian Railways both for the passenger traffic and the goods traffic.

Detailed explanation-5: -The Common Rail Electronic Direct Injection (CReDI) fuel system will be retrofitted/ fitted on the 6 cylinder inline 1350 hp ALCO diesel engines used on diesel locomotive of Indian Railways. The CReDI fuel system shall be used on the newly built or during rebuilding.
