The Indian locomotive class '''WDM-6''' is a class of [[Diesel–electric locomotive|Diesel]] locomotive that was developed in 1981 by [[Banaras Locomotive Works]] (BLW), Varanasi for [[Indian Railways]]. The model name stands for [[5 ft 6 in gauge railway|broad gauge (W)]], Diesel (D), Mixed traffic (M) engine, 6th generation (6). They entered service in 1981. A total of 2 WDM-6 was built at between 1981 and 1982. They were decommissioned at [[Barddhaman Junction railway station|Burdwan]] (BWN) in 2011.<br />
<br />
<br /><br />
<br />
== History ==<br />
WDM-6 was developed to address the need for locomotive to haul commuter and suburban services. They had the same 1350hp engine and hood superstructure as the [[Indian locomotive class YDM-4|YDM-4]] locos with [[Indian locomotive class WDM-2|WDM-2]] under frame. but these locos were underpowered and subsequently relegated to shunting and departmental duties. They were based at the diesel locomotive shed in [[Barddhaman Junction railway station|Burdwan]] (BWN) since 1980s. One unit was seen shunting at Liluah Workshop. <br />
By late 2010s they were withdrawn from services. Both units are earmarked for preservation.<br />
