Which was the first zone to be created when Indian Railways was reorganised in 1951?

The correct answer is B, Bori Bunder and Thane. On 16 April 1853 the first passenger train in India ran about 34 kilometres from Bori Bunder in Bombay to Thane on the line of the Great Indian Peninsula Railway, drawn by three locomotives named Sahib, Sindh and Sultan. Option A is wrong but it is a real event of the next year, since the first train in eastern India ran in 1854 from Howrah to Hooghly on the East Indian Railway. Option C is wrong; the Madras Railway opened its first passenger line in 1856, three years after Bombay. Option D is wrong because the Bombay to Poona route is remembered for the Deccan Queen of 1930 and not for the first train. Fix the triple of 1853, Bori Bunder and Thane, because a paper may ask for the year, the stations or the distance separately.

The correct answer is C, Gorakhpur. The North Eastern Railway has its headquarters at Gorakhpur in Uttar Pradesh, and the zone despite its name serves eastern Uttar Pradesh and northern Bihar rather than the north eastern states. Option A is wrong, and it is the intended trap, because Guwahati, or more precisely Maligaon in Guwahati, is the headquarters of the Northeast Frontier Railway, a different zone whose name is only one word apart. Option B is wrong since Hajipur in Bihar is the headquarters of the East Central Railway. Option D is wrong because Prayagraj is the headquarters of the North Central Railway. The safest way to hold these is by the pair of similar names: North Eastern goes with Gorakhpur and Northeast Frontier goes with Maligaon in Guwahati.

The correct answer is B, South Central Railway. The South Central Railway has its headquarters at Secunderabad in Telangana. Option A is wrong because the South Western Railway is headquartered at Hubballi in Karnataka, an answer worth learning separately because the spelling changed from the older Hubli. Option C is wrong; the South East Central Railway has its headquarters at Bilaspur in Chhattisgarh. Option D is wrong because the East Coast Railway is headquartered at Bhubaneswar in Odisha. All four zones carry a compound direction in their names, which is exactly why the paper setter groups them, so revise the southern block together: Chennai for Southern, Secunderabad for South Central, Hubballi for South Western, Kolkata for South Eastern and Bilaspur for South East Central. The headquarters city, not the state, is what the paper wants.

The correct answer is B, Dibrugarh. The Vivek Express runs between Dibrugarh in upper Assam and Kanniyakumari at the southern tip of the mainland, covering roughly 4,200 kilometres, the longest route of any train in the country. It was introduced in 2011, the one hundred and fiftieth birth anniversary year of Swami Vivekananda, which is how it got its name. Option A is wrong; Guwahati is the largest station of the region and the headquarters city of the Northeast Frontier Railway, but the Vivek Express starts further east. Option C is wrong because Silchar lies in the Barak valley and is not a terminus of this train. Option D is wrong; Agartala in Tripura was connected to the broad gauge network much later and has its own long distance trains, but not this one. Remember the pair Dibrugarh and Kanniyakumari as the two ends of the country.

The correct answer is C, the Darjeeling Himalayan Railway, inscribed in 1999 as the first of the three lines that together form the World Heritage property called the Mountain Railways of India. Option A is wrong because the Nilgiri Mountain Railway in Tamil Nadu, the only rack railway in India, was added to the same property in 2005. Option B is wrong since the Kalka to Shimla Railway in Himachal Pradesh was added in 2008 and is therefore the last of the three. Option D is wrong because the Matheran Hill Railway in Maharashtra is a narrow gauge heritage line that has been proposed for inscription but is not part of the property. Note that the fourth railway heritage site in India is not a line at all but the Chhatrapati Shivaji Maharaj Terminus building in Mumbai, inscribed in 2004.
