Bori Bunder (alternatively "Bori Bandar") was one of the areas along the Eastern shore line of Mumbai, India which was used as a storehouse for goods imported and exported from Mumbai. In the area's name, 'Bori' mean sack and 'Bandar' means port or haven (in Persian); So Bori Bunder literally means a place where sacks are stored. In the 1850s, the Great Indian Peninsular Railway built its railway terminus in this area and the station took its name as Bori Bunder.On 16th April, 1853 the Great Indian Peninsula Railway operated the historic first passenger train in India from Bori Bunder to Thane covering a distance of 34 km, formally heralding the birth of the Indian Railways. The train between Bori Bunder and Thane was 57 minutes it was a distance of 35 km apart.

The station was eventually rebuilt as the Victoria Terminus, named after the then reigning Queen, and has been subsequently renamed Chhatrapati Shivaji Terminus (CSTM) after Maharashtra's and India's famed 17th century king. Though the shortened name is now CST, it still continues to be referred to as VT by the masses.
The station was designed by the consulting British architect Frederick William Stevens(1848-1900). Work began in 1878. He received 1,614,000 (US$32,199.3) as payment for his services.[1] Stevens earned the commission to construct the station after a masterpiece watercolour sketch by draughtsman Axel Haig.[1] The final design bears some resemblance to the St Pancras railway station in London.[1][5] GG Scott's plans for Berlin's parliament building had been published four years before, and also has marked similarities to the station's design.[6]
It took ten years to complete[5] and was named "Victoria Terminus" in honour of the Queen and Empress Victoria; it was opened on the date of her Golden Jubilee in 1887.[5][7] It cost £260,000 when it was finished in 1888, the highest for any building of that era in Bombay.[6] This famous architectural landmark in Gothic style was built as the headquarters of the Great Indian Peninsular Railway. Since then, the station came to be known as Bombay VT.
Originally intended only to house the main station and the administrative offices of the Great Indian Peninsula Railway, a number of ancillary buildings have been added subsequently, all designed so as to harmonise with the main structure. A new station to handle main line traffic was erected in 1929. The original building is still in use to handle suburban traffic and is used by over three million commuters daily. It is also the administrative headquarters of the Central Railway.
In 1996, the Minister of Railways, Suresh Kalmadi, changed the name of the station to Chhatrapati Shivaji Terminus[8][9] in honour of the great Maratha king Chhatrapati Shivaji.
In 2008, the station was featured prominently in the Academy Award winning film, Slumdog Millionaire. In 1956, the station was also featured in the film C.I.D. during the song 'Yei Hai Bombay Meri Jaan'.
distance.Plans are underway to upgrade Mumbai CST (along with Pune Jn. and Nagpur Jn.) by means of a public-private partnership.
The network of suburban trains (locally known as locals, short for local trains) radiating out from this station is instrumental in keeping Mumbai running. The station serves long-distance trains as well as two of the suburban lines-the Central Line and the Harbour line. It is the westernmost terminus of Central Railway. On the Central Line the trains terminate at Kurla, Ghatkopar, Thane, Dombivli, Kalyan, Ambarnath, Badlapur, Karjat, Khopoli, Asangaon, Titwala, and Kasara. While on the Harbour Line, the trains terminate at Bandra, Andheri, Mankhurd, Vashi, Belapur and Panvel.
CST has 18 platforms - six are for locals trains and 12 are for long distance.
