Which one of the following sets of states benefits the most from the Konkan Railway?

Answer: (a) Goa, Karnataka, Maharashtra, Kerala

The Konkan Railway runs Roha (Maharashtra) → Goa → Karnataka → Thokur near Mangaluru, benefiting Maharashtra, Goa, Karnataka and Kerala.

The idea

A railway’s beneficiaries include places beyond the States containing its track. A coastal link can shorten journeys for a neighbouring State connected at its terminal. Distinguish the direct route footprint from the wider transport corridor.

Why the others are wrong

(b) MP and TN are not on the route.

(c) Tamil Nadu is not on the route.

(d) Gujarat and TN are not on it.

Also know

The Konkan Railway runs between Roha in Maharashtra and Thokur near Mangaluru in Karnataka, through Goa. Kerala connects farther south through the existing rail network. Heavy rain, steep slopes and short west-flowing rivers require tunnels, bridges and careful slope protection along this coast.
