Great capture. This shows the importance SR/MDU shows towards GREAT Vaigai.
Vaigai loco change was issued as press release.
Loco decorated.
Pallavan/GUV/Sethu/Pandian/Pothigai all were earlier halued by WAP 7 before Vaigai but none did get this importance from divisional railways.
Seems...
more... like they are test eli for Vaigai. Just kidding.
