Electric Loco Shed, Asansol is a motive power depot performing locomotive maintenance and repair facility for electric locomotives of the Indian Railways, located at Asansol of the Eastern Railway zone in West Bengal, India.

[4] To meet the needs of exponentially increasing rail traffic on the new continuous broad-gauge lines from kolkata to rest of India with the completion of gauge conversion, the Asansol was selected by Indian railways for a new electric locomotive shed.

The original WAM-1/2 locos, having ignitrons for AC-to-DC conversion, were converted to silicon rectifier system in the years 1968 to 1970.

CLW started production and the first batch of 10 WAG-4 locos were commissioned and based at Asansol shed in 1970.

Beyond the operating capacity, this shed houses a total of 207 engine units, including 90 WAP-4 and 19 WAP-7.

ASN locomotives used to be predominantly the regular links for trains traveling to north as well.

Though WAP-4 class have a standardized livery all over India, Asansol WAP-4 locomotives can easily be recognized by their Blood Red with incomplete yellow band.
