Frontier Mail

The Frontier Mail was flagged off on Sep. 1, 1928, from Colaba Terminus, the main station on the BB&CI (later Western Railway). It was a replacement for the earlier Mumbai-Peshawar Mail. In winter (Sep. - Dec.), the Frontier Mail started from Ballard Pier (Mole Station) to connect with P&O steamships; this is the portion referred to as the "Duplicate" section of the Frontier Mail in old railway schedules and articles.
Leaving from Mole Station the train ran for a short while on tracks of the Bombay Port Railway and the GIPR via Bandra Jn. finally reaching its home tracks of the BB&CI Railway. For the rest of the year the train terminated at Colaba, but a separate train ran to Ballard Pier for the steamer connection. There were also times when the train ran this extra bit on some days of the week alternating with the normal route.
The train's route took it through Baroda, Ratlam, Mathura, Delhi, Lahore, Rawalpindi, and finally to Peshawar. (The section beyond Delhi was run by the North Western Railway as train No. 3.) Peshawar was close to the frontier of British India in those days, hence the name of the train. It used to be the fastest long-distance train in the subcontinent.
Originally the BB&CI introduced it to rival the Punjab Limited of the GIPR, which also went from Bombay to Peshawar. The train had a reputation for being unusually punctual. Originally the rake had 5 coaches and a luxury dining car cum lounge car. As a prestige train of the BB&CI, the train offered plush conveniences on board, and the passengers had access to luxurious retiring rooms at stations along the way. It had air-cooled cars (using ice blocks) from about 1934.
After Independence, it went only up to Amritsar, via Delhi, from Bombay. The train has now been renamed "Golden Temple Mail".
