Next locomotive is WDP 3A. The locomotive WDM 2 was later renamed as WDP 3A. This blog would be lengthy so I have divided this blog into later 2 parts, Part-IV & Part-V coming later. So the next locomotive now is WDP 4. The WDP 4 had changed Indian passenger diesel services for ever. These 4000 hp single cab-forward behemoths that took India by storm were originally the GT46PAC exclusively built and supplied for the Indian Railways by EMD, USA in 2001. The first few units were fully imported and then some were assembled in India from CKD units before DLW started manufacturing them in India. #20012 “Baaz” was the first fully-Indian produced unit and most were homed at Hubli (UBL). These EMDs were light-years ahead of most ALCOs by being technologically well advanced with unit fuel injection, self-diagnostics, microprocessor control for optimum power delivery to traction motors etc. The WDP4s did good service though they are not being produced anymore(produced till 2011). They could reach a top speed of 160 kmph.
