The first UDAY (Utkrisht Double Decker Air-Conditioned Yatri) Express train runs between
- (a)Delhi and Kalka
- (b)Bengaluru and Coimbatore
- (c)Chennai and Visakhapatnam
- (d)Chennai and Bengaluru
Correct — B, Bengaluru and Coimbatore. As of the November 2019 exam, India's first UDAY (Utkrisht Double Decker Air-Conditioned Yatri) Express ran on the Coimbatore–Bengaluru route, having been flagged off in June 2018. Announced in the 2016-17 Railway Budget, the UDAY is a fully double-decker air-conditioned chair-car service designed for high passenger density on busy short-haul intercity corridors.
- (a)Delhi and Kalka — The Delhi-Kalka corridor is served by trains like the Shatabdi and the Himalayan Queen, not the first UDAY Express.
- (c)Chennai and Visakhapatnam — No first UDAY Express ran on this route; a later UDAY service operated between Visakhapatnam and Guntur, not Chennai.
- (d)Chennai and Bengaluru — A plausible-sounding southern pairing, but the inaugural UDAY linked Coimbatore with Bengaluru, not Chennai.
The UDAY Express is a category of double-decker, air-conditioned chair-car trains introduced by Indian Railways to move more passengers on high-demand short intercity routes. Its two-tier coaches seat far more travellers than a conventional AC chair car.
The distractors are all real rail corridors. Anchor the 'first' UDAY to the southern Coimbatore-Bengaluru line, flagged off in 2018; a second UDAY (Visakhapatnam-Guntur) came later.
