(i) Fare is the amount charged by the railways to carry passengers, while freight is the amount charged by the railways to transport goods and luggage from one place to another. (ii) There is a distinct contrast in the rail network between the Eastern and Western coastal plains. There exists a long trunk route all along the east coast but such a rail track is missing along the western coast from Mumbai to Kochi. The outcrops of the Western Ghats being very close to the coast, restrict the extent of the coastal plain while the eastern coast is wider and the Ghats lie away from the coast. Now, Konkan Railway Corporation has been constituted to construct west coast rail line, which is one of the most important achievement of Indian Railways and it is considered as an engineering marvel. It crosses 146 rivers, nearly 2000 bridges and 91 tunnels. Asia’s largest tunnel, which is nearly 6.5 km long, also lies on this route. The states of Maharashtra, Goa and Karnataka are partners in this undertaking.
