The distance between which two successive stations is the second lowest?

Distance between Dadar and Vasai Road = 42 km

Distance between Vasai Road and Surat = 257 - 42 = 215 km

Distance between Surat and Vadodara = 386 - 257 = 129 km

Distance between Vadodara and Anand Junction = 422 - 386 = 36 km

Distance between Anand Junction and Nadiad Junction = 440 - 422 = 18 km

Distance between Nadiad Junction and Ahmedabad = 486 - 440 = 46 km

Distance between Ahmedabad and Bhuj = 977 - 486 = 491 km

=> Secong lowest distance = 36 km between Vadodara to Anand Junction.
