I was on a railfanning trip to a station named Ghoraghata (GGTA) on the Kharagpur- Santragachi stretch of SER (South Eastern Railways). As my EMU from Howrah was approaching a station named Fuleshwar, I saw a unique liveried train approaching from Kharagpur side with a WAG- 7 in lead. As I started recording the video, I realized it was the brand new rake of ANTYODAYA Express headed by a 27009 MGS WAG- 7 in lead.
The entire rake consisted of 22 coaches (20 GS+ 2 EOG), and was booked for SER's SRC base. The rake would be used either for the Howrah (HWH)- Ernakulam (ERS) ANTYODAYA, or the Santragachi (SRC)- Chennai Central (MAS) ANTYODAYA.
Now, I have quite a few queries regarding the train, listed below.
1) The EOGs were marked with 160 km/hr top speed. But the GS coaches had 2 set of markings, as 105 km/hr and 130 km/hr (You can freeze the video, and check). Why is it so?
2) Other than being a LHB rake sporting a new livery (And having extra sets of seats instead of the luggage rack), it this ANTYODAYA in anyway different than the JAN SADHARAN/ JAN SEWA/ JAN NAYAK set of train? Or is it just Old Wine in New Bottle??
