Subsequently, the project was further extended beyond Vadodara in a north easterly direction towards Godhra, Ratlam, Nagda and thereafter northwards towards Kota and Mathura, to eventually link with the Great Indian Peninsular Railway, now the Central Railway, which had already started operating in Mumbai in 1853. In 1860 Surat railway station was built and it was first railway station in Asia which is having platform on first floor (above ground level). In 1883, a metre-gauge railway system, initially linking Delhi with Agra, Jaipur and Ajmer, was established.
