ALCo WDG-3A Diesel Locomotive Start-up & Idling sounds at Kollam Jn. | Indian Railways ALCo 251-C

Wonderful idling sounds of WDG-3A Locomotive from Golden Rock Diesel shed(GOC-D), loco number is 13536. Enjoy the audio of the ALCo engine idling, just minutes prior, the locomotive had been started up. It was to haul the 16102 Kollam - Chennai Egmore Express (Kollam Mail) that day. The Indian locomotive class WDG-3A is a class of diesel–electric locomotive that was developed in 1994 by Banaras Locomotive Works (BLW),Varanasi for Indian Railways. The model name stands for broad-gauge (W), Diesel (D), Goods traffic (G) engine, 3,100 hp (3A) locomotive. They entered service on 18 July 1995. A total of 1,164 WDG-3A units were built between 1994 and 2015 at BLW, Varanasi with a few units being produced by Diesel Loco Modernisation Works (DLMW) and Parel Workshop. It is the dedicated freight version of the highly successful WDM-2 and shares the same engine and horsepower rating with WDM-3A. It is considered to be a successful locomotive class with high reliability and few maintenance problems. 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 October 2025, 402 locomotives still retain "operational status" on the mainline as WDG-3A, with a few examples having been converted to WAGC-3 or WAG-10. The first units of this class was delivered on July 18, 1995, under the name of WDG-2. The class was manufactured till end of 2015. All the older locomotives built by DLW had regular WDM-2 type square short hood profile and control stand position and the locomotives are rated at 3,100 HP. From 2009 onward, they are equipped with Daulat Ram DBR, microprocessor control and an Auxiliary Power Unit (APU) in the short hood thus they bear external resemblance to the WDM-3D class. The WDG-3A has higher Tractive Effort (7.5 t more) and Axle Load (1.7 t) compared to the WDM3A despite having the same engine and horsepower rating. Many units of this class has been named "Shakti" and can easily be recognized by their orange livery with cream stripe & lightning bolts. Besides IR, WDG-3A are being use by private companies for industrial uses, thermal power plants, port trusts, etc. Production was stopped in 2015 when advanced locomotives like the WDG-4D were built, thus rendering the ALCO platform obsolete. Two WDG-4s can haul more goods than three WDG-3A combined. Meanwhile, Diesel Loco Works in Varanasi rebuilt few of the existing locomotives that had reached midlife into a purely electric twin section 10,000 hp (7,457 kW) locomotive, classifying them as the WAG-C3/WAG-10. #kerala #diesellocomotive #wdg3a #alco #251C #indianrailways #trainsofindia #idlingsound #trainvideos #locomotivesounds
