About: Indian locomotive class WDM-3A

An Entity of Type: mean of transportation, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Indian locomotive class WDM-3A is a class of diesel–electric locomotive that was developed in 1993 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, with 3300 horsepower (3A). The WDM-3A is a later classification of earlier WDM-2C. They entered service in 1994. A total of 143+ were built at ALCO and Banaras Locomotive Works between 1994 and 2003 with rest of the 1246 units being rebuilt from WDM-2 which made them the most numerous class of mainline diesel locomotive until the WDG-4.

  • The Indian locomotive class WDM-3A is a class of diesel–electric locomotive that was developed in 1993 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, with 3300 horsepower (3A). The WDM-3A is a later classification of earlier WDM-2C. They entered service in 1994. A total of 143+ were built at ALCO and Banaras Locomotive Works between 1994 and 2003 with rest of the 1246 units being rebuilt from WDM-2 which made them the most numerous class of mainline diesel locomotive until the WDG-4. The WDM-3A is one of the most successful locomotives of Indian Railways serving both passenger and freight trains for over 26 years. A few WDM-3A units were exported to neighboring countries like Sri Lanka and Bangladesh. Despite the introduction of more modern types of locomotives like WDG-4 and electrification, a significant number are still in use, both in mainline and departmental duties. As of April 2022, 769 locomotives still retain "operational status" on the mainline as WDM-3A, with further examples having been converted back to WDM-2 or WDM-2S. The loco is now widely used across India for long-distance passenger trains due to its ruggedness and high tractive loads and acceleration. (en)
  • 印度鐵路WDM-3A型柴電机车是1993年由瓦拉纳西的巴拿拉斯機車廠（Banaras Locomotive Works，BLW，原名為Diesel Locomotive Works ，DLW）为印度铁路开发的柴电机车。型号名称代表宽轨 (W) 、柴油 (D)、混合交通 (M) 发动机，具有 3300 马力 (3A)。 WDM-3A于 1994 年啟用，於1994 年至 2003 年间，ALCO 和 Banaras 机车厂共新造143 多台，其余 1246 台由 WDM-2改造而成，在 WDG-4 出現，WDM-3A是印度鐵路數量最龐大的幹線用內燃機車。 WDM-3A 是印度铁路最成功的机车之一，牽引客运和货运列车超过 26 年，並有少數出口到斯里兰卡和孟加拉国等邻国。雖然後來引進了更現代化的機車（如WDG-4）以及路線電氣化，仍有大量WDM-3A使用於幹線列車以及各單位內；2021 年仍有803 辆机车在幹線保持可运行状态，而其他的機車則改造回WDM-2或 WDM-2S。由于可靠性、高牵引力與加速度，本型車廣泛用於印度各地的長途客運列車。 (zh)
