The
East Indian Railway Company initiated efforts to develop a railway line from Howrah to
Delhi in the mid nineteenth century. Even when the line to Mughalsarai was being constructed and only the lines near Howrah were put in operation, the first train ran from Prayagraj to
Kanpur in 1859. For the first through train from Howrah to Delhi in 1864, coaches were ferried on boats across the
Yamuna at Prayagraj. With the completion of the
Old Naini Bridge across the Yamuna through trains started running in 1865–66. The opening of the Curzon Bridge, across the Ganges, in 1902, linked Prayagraj to regions north of or beyond the Ganges. The Varanasi–Prayagraj City (now called as
Prayagraj Rambagh railway station) line was constructed as a metre-gauge line by the Bengal and North Western Railway between 1899 and 1913. It was converted to broad gauge in 1993–94. The state government changed the name of the station from Allahabad Junction to Prayagraj Junction in February 2020. ==Electrification==
