WDM3D Locomotive - Diesel Engine Idle and Compressor sounds - ALCO DL560C

Описание: The Indian locomotive class WDM3D is a class of diesel-electric locomotive that was developed in 2003 by Diesel Locomotive Works (DLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine with 3300 horsepower (3D). The engine is classified WDM3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Diesel Locomotive Works (DLW), Varanasi between 2003 and 2016.

The WDM3D is one of the most successful locomotives of Indian Railways serving both passenger and freight trains. A few WDM-3D units were exported or gifted to neighboring countries like Sri Lanka and Bangladesh. A significant number of these locomotives are still in use, both on mainline and departmental duties.

It is the higher-powered version of the Indian locomotive class WDM3A. These locos have a 3300 hp power pack, with maximum available traction power of 2925 hp. The engine is an enhanced version of the 16-cylinder Alco 251C model with a max. speed of 160 km/h. The bogies are Improved Fabricated (welded) Alco High-Adhesion Co-Co bogies with stem type vertical and lateral dampers in place of 'eye' type which helps reduce wheel slip and maintenance.

The loco features left hand drive, WDG3A style High Adhesion bogies, air cylinder under foot-board, WDP4 style fuel tanks, engine doors like WDP4, marker lights outside cabin doors, electronic horn, high capacity buffers. Components and auxiliaries have been improved with the aim of making the duty schedule longer between maintenance visits to the shed.
