The mileage of locomotives is a crucial factor in railway operations. ALCO (American Locomotive Company) and EMD (Electro-Motive Diesel) are two prominent types used in Indian Railways.
- ALCO Locomotives:
- Known for their robustness, ALCO locomotives have a Specific Fuel Consumption (SFC) of around 154-156 grams per brake horsepower hour (g/bhp.hr).
- They are widely used for both passenger and freight services.
- EMD Locomotives:
- EMD locomotives, such as the WDP-4 series, are more fuel-efficient with an SFC of approximately 151 g/bhp.hr.
- These locomotives are preferred for their higher power output and better fuel economy.
In summary, while both types are integral to Indian Railways, EMD locomotives offer better mileage and efficiency.
