The 12903/12904 Golden Temple Mail is a super fast express train belonging to Indian Railways that runs between Mumbai Central and Amritsar in Punjab. It is a daily service. It operates as train number 12903 from Mumbai Central to Amritsar and as train number 12904 in the reverse direction.
The Golden Temple Mail was until September 1996 known as Frontier Mail.
Prior the Partition of India, it would run up to Peshawar on British India’s frontier with Afghanistan from which it derived its name.
During the autumn months between September and December, the train used to depart from the Ballard Pier Mole station. This was for the convenience of the British who arrived in India by steamer.
According to the officially recognized biography of Subhas Chandra Bose, the Indian revolutionary escaped from house-arrest in Calcutta to Bombay and from there to Peshawar by the Frontier Mail.
The Frontier Mail also finds a place in romanticized biographies of film actor Prithviraj Kapoor who is believed to have travelled to Bombay from his hometown of Peshawar by the Frontier Mail in 1928 to act in films.
The Frontier Mail was the first air conditioned train in the Indian Peninsula, when it got an air-conditioned compartment in 1934.
The radio facility was provided for the first time in the Golden Temple Mail.
