WDP4 | WDG 4 | Diesel electric locomotives | EMD | WDP4B | WDP4D | WDG4D | General Motors

General Motors EMD (Electro-motive Diesel) locomotives have dominated the non-electrified tracks of India since 1999 when the WDG4 started operations in India. But the WDG4 and WDP4 were not the first EMD locomotives in India. That honour goes to the WDM4 a.k.a EMD SD24! The WDM4 was EMD's offer to Indian Railways against the ALCos DL560 series locomotives in the 1960s. Even though the EMD SD24 (WDM4) was technically superior to the ALCo DL560 (WDM2), EMD could not gain foothold in India because of its refusal to transfer technology. But 30 years later, EMD chastened by its earlier error in Judgement, offered full transfer of technology with its GT46MAC (WDG4) and GT46PAC (WDP4) diesel electric locomotives. Today the EMD siblings dominate the non-electrified diesel territories of Indian railways. This video tells the story of these iconic locomotives in India.

EMD is a silent beast it is first loco capable to go over 100 mph It outperforms great ALCO locos. Speed , noise, traction and acceleration . Personally I like single cab EMD. EMD + frieght car is great combo ALCO + ICF Cars is also great sight.

[@RockyRailroadProductions_B0SS]

Really good explanation of these locomotives, I learned quite a lot from this! What really interested me was the early EMD competitor with ALCO being preserved at the National Railway Museum, and the issues of running such a long locomotive with the long hood forward - EMD makes locos like that for use here in the states, where it is common to see two or three leading a train, but it definitely makes sense why some of the WDP4s had the second cab added. Good motion graphics as well!

[@TheTrainStory]

Yes the long hoods can be a hassle here in India because at least in the case of passenger trains, locomotive are not assigned in Multiple Unit configuration.

Is there any matter of series parallel transition in EMD's just like ALCO's?

[@prasannask2684]

My one peeve is, Indian railways hasn't invested in loco reversers at major locations which could reversed the loco so that loco would run with front cab /short hood ahead. Many times accidents have happened due to misjudgement and miscalculations done due to loco being driven with long hood ahead.

[@TheTrainStory]

You mean “railway turntable”. In the age of steam, IR had railway turntables. In fact they were quite common. The advent of diesel and electrics reduced IR’ need for turntables and have been phased out.

Long hood forward is the main problem for locopilots 🙏🏻

[@TheTrainStory]

The EMDs were designed for MU’d operations where the long hood forward would never have come into play. In India where the locos are used as single units, the LHF visibility became a problem. IR has addressed this by adding cabs at both ends…In Europe, where single units are prevalent, EMD supplied twin cab units…

[@mongoose1618]

I hope Indian railways don't convert all EMDs to electric. Personally I would love to see few EMD-hauled versions of some trains run maybe once a month. A heritage special . It would be a great thing for railfans.

Nice video. No hard feelings, but love the sound of alcos much more than wdps. And even more, the steam engines. The sound and the look of the locomotive I feel, is key to the journey. Looking at the mammoth steamer, the horn and the sound the engine makes the journey feel complete.Inckudimg the alcos. The sound on acceleration is so awesome. instead of a steamer, Imagine, the grand Indian train driven by a wap. Wouldn't it be great? Well, it saddens me that the waps look like dhabbas. No acceleration sound, no looks nor the horn sound. Zero personality. I feel Its like better to have the train driven by self electrified boggies than to have that dhabba in the name of a locomotive. I mean a local will also do. Ah yes, it's pollution free. But not what I account for when traveling by train. Once upon a time a train lover. It's been almost 7 years now I stepped into a train.

Yes right that if GM agreed to share technical aspects to IR then it was the PRIMARY MAIN LINE DIESEL LOCO INSTEAD OF ALCO DL560 ie WDM 2

[@trainfanner47]

There are two reasons for MUs of EMDs: 1. Incase of loco failure, the other loco can take over. 2. Superior acceleration and deceleration so as to speed up trains between single line/heavy traffic sections.

[@TheTrainStory]

In the case of the Kochuveli express the MU was probably for loco failure/loco testing. The 2nd option doesn’t seem the case here because other trains on the same route were running with single locos.

[@trainfanner47]

@@TheTrainStory The second option is being used in zones like SBC (Bengaluru) division of SWR, due to surplus amount of diesel locos available. Examples include: •Jaipur express from YPR (Yeshwanthpur) •KCVL express to MYS (Mysore) •BGM (Belagavi) express from •Rani Chennamma express (To Miraj) •Mayiladuthurai express from MYS (after loco change at SBC) Another reason is that, as a single loco, hauling a 21+ coach lhb rake or 23+ coach ICF rake takes a toll on the loco and reduces it's efficiency significantly.
