The exact history of the Island Express is somewhat hazy as surprisingly there are no accurate reports available about the early origins of the train. Legend passed down word of mouth has it that the train that is called the
Island Express today started its run in the 1940s as some 3 or 4
slip coaches attached to an ancient 562/561 Cochin–Madras Express which ran out of Cochin Harbor Terminus (CHTS). The
slip coaches attached to this would then be detached at Jolarpettai and attached to another train (Bangalore Mail) which would take them to Bangalore. Years passed by and sometime in the 1960s, these slip coaches grew into a separate train which was christened the 25/26 Cochin–Bangalore–Cochin Island Express. It continued to run between Cochin Harbor and Bangalore until 1976 when the Ernakulam–Kottayam–Thiruvananthapuram route was converted to broad gauge. The Island then had to say goodbye to its island as it was
extended to Thiruvananthapuram. As new lines were commissioned it was extended to Nagercoil in 1988 and subsequently to Kanniyakumari in 1992. The Island Express briefly had through coaches to Mangalore Central where It used to be attached/detached to the Link Mangala Exp (2625A/26A) at Palakkad Jn. This continued until 1993 when Mangala Exp was made an Independent Train. From 1993 onwards until 2000, The coaches were linked to the newly started 387/388 Coimbatore Mangalore Coimbatore Fast Passengers at Palakkad Jn. The erstwhile 19/20 Cochin–Madras Express is today's illustrious 12624/12623
Chennai–Trivandrum Mail (Madras Mail) and the 25/26 Island Express is today officially, the 16525/16526 Kanyakumari–Bangalore "Island" Express. The Island Express derives its name from the Willingdon Island, on which the CHTS station is situated and from where the train started its journey.
The Express that goes to an Island, so very obviously brilliant. The name got so entrenched with the public, that even though it is no longer the official name of the train, it is still called so.
The train lost Island as its official railways-recognized name once its destination was moved from Willington Island to TVC, NCJ and CAPE. Its official name today is Kanyakumari Express and Bangalore Express for the respective destinations. But the travelling public still calls the train The Island Express, reminiscent of its old name almost two generations ago, popularly and lovingly. Maybe no one uses the official names as there are other Bangalore and Kanyakumari Expresses and destination place names are not popular as train names anyway. ==Accidents==
