The Bombay, Baroda and Central India Railway (reporting mark BB&CI) was a company incorporated in 1855 to undertake the task of constructing railway lines between Bombay to the erstwhile Baroda State, that became the present-day Baroda (Vadodara) city in western India. BB&CI completed the work in 1864. The first suburban railway in India was started by BB&CI, operating between Virar and Churchgate (later extended to Colaba), a railway station in Bombay Backbay in April 1867. The railway was divided into two main systems, broad (5 ft. 6 in.) and metre gauge. There was also a comparatively small mileage of 2 ft. 6 in. gauge line worked by the BB&CI on behalf of the Indian States. In 1947 the mileage of the respective portions was stated to be: broad gauge, 1,198 miles, with a further 69 miles worked for Indian States; metre gauge, 1,879 miles, with a further 106 miles worked for Indian States; narrow-gauge, 152 miles, worked for Indian States and various companies. Quadruple track mileage was 22 and double-track 250, the remainder of the system being single-track, whilst running powers were exercised over 147 miles (including the important section from Muttra Junction to Delhi, owned by the Great Indian Peninsular Railway). The main headquarters of the BB&CI Railway was located at Churchgate, Bombay and the headquarters and workshops for the metre gauge tracks and services was located in Ajmer. Description of systems The broad-gauge main line ran northwards from Bombay to Baroda, where it bifurcated, the north-east main line continuing towards Delhi, and the north-west main line to the industrial city of Ahmedabad and onwards to Viramgam and Kharagoda. The north-east main line passed through Godhra, Ratlam, Kotah and Bayana (from where a branch line ran to Agra Fort), to Muttra Junction, where it joined the Great Indian Peninsular Railway, over which it had running powers for 90 miles into Delhi. The metre-gauge system was originally the Rajputana Malwa State Railway. It began at Ahmedabad and ran northwards through Baroda State and Rajputana via Abu, Ajmer, Jaipur and Rewari to Delhi. There were branches from Rewari to Bhatinda and Fazilka, from Ajmer to Ratlam, Indore and Khandwa, and from Achnera to Cawnpore. Organisation The original Bombay, Baroda & Central India Railway Company was purchased by the Government of India in 1905, but continued to be worked by a company with a board of directors in London until 1 January
