  • Upgradation of ALCO Locomotive Design
    UPGRADATION OF ALCO LOCOMOTIVE ENGINE DESIGN - THE IN-HOUSE EFFORT BY INDIAN RAILWAYS ABSTRACT 2600 HP, 16-Cylinder engine diesel locomotives were introduced on Indian Railways in early 1960’s with the transfer of technology from American Locomotive Company (ALCO), USA. The diesel engines of above design continued to be manufactured in the Production Unit of Indian Railways at Diesel Locomotive Works, Varanasi for about 25 years without any modifications. To improve the technology of above engines to achieve improved fuel efficiency and increase in the power without major change in the basic engine configuration, Engine Development Directorate was set up by Indian Railways in 1980’s in their R&D Centre (Research Designs & Standards Organisation) at Lucknow. Since then, sustained efforts have been made by Indian Railways to achieve the above objectives. In the first stage, various modifications were taken up in the original 16-cylinder 2600 HP ALCO engines to reduce its fuel consumption by more than 6% and lube oil consumption by about 15%. These modified engines were called 2600 HP (FE) Engines. In the second stage, the uprating of the engine was carried out from 2600 HP (FE) to 3100 HP along with the improvement in fuel economy to 8% and lube oil consumption reduction to 25%. In the third stage, the technological improvements were made to further uprate the engine to 3300 HP/3600 HP and improve its fuel efficiency by 9.6% and lube oil consumption reduction by 33%. The modifications in the fourth stage are the modifications, which have been tested on test Beds of RDSO but are yet to be implemented on locomotives.

Describe Required different type of facilities Machinery & Plant with other facilities? ANS- Following factors should be considered while finalizing the shed lay out :- • A uni-directional movement of locomotive in the shed is preferable. • Separate entrance and exit points should be provided to avoid bottlenecks. • The layout should permit a locomotive to skip stage of servicing without hampering the flow of Other locomotives. • The shed should have covered accommodation in its repair area for about 25-30% of the fleet Homed. The yard of the maintenance shed should be able to hold at a time about 50% of the total Holding of the shed. • Each line in the covered repair area of the shed should be able to hold 3 locomotives. The layout should provide for possibility of expansion width-wise i.e. by providing more lines side by side. Following point should be considered while constructing a Shed :- • The shed should have three level working floor arrangements. • This facilitates simultaneous and expeditious maintenance service as well as repairs. • The flooring should be such that spilt oil can be easily removed. • Pits should have convex flooring and efficient drainage. • Flooring in heavily lifting bays should be strengthened.
