Q1. The first UDAY (Utkrisht Double Decker Air-Conditioned Yatri) Express train runs between:
A Delhi and Kalka
B Bengaluru and Coimbatore Correct
C Chennai and Visakhapatnam
D Visakhapatnam and Vijayawada
Explanation
UDAY Express was introduced as a double-decker, air-conditioned train service for high-demand routes. The first UDAY Express ran between Bengaluru and Coimbatore, so that pairing fits the question. Delhi and Kalka is known for other services on the northern route, not the first UDAY service. Chennai and Visakhapatnam and Visakhapatnam and Vijayawada are railway routes in the south-eastern region, but they were not the inaugural UDAY Express pairing. The answer is therefore retained as Bengaluru and Coimbatore.
