Video talks about why ALCO gained early market share, and how EMD is now the dominant diesel loco model.
The model numbers are a little confusing. He talks about the WDM4 (SD-24), and the more modern WDG4 and WDP4. Don't know the North American equivalents to those models.
"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
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."
