The Kingston to Montego Bay railway was the main railway in Jamaica, which from 1845 to 1992 linked the capital Kingston with the second city Montego Bay, passing en route most of the major towns.
Construction, operation and closure.
The first of (standard gauge) track were laid from Kingston to Angels (just north of Spanish Town) in 1845 at a cost of £222,250, or £15,377 per mile against a budgeted cost £150,000.
An extension from Spanish Town to Old Harbour was added in 1869 at a cost of £60,000.
A further extension from Old Harbour to Porus was added in 1885 at a cost of around £187,000.
The final from Porus to Montego Bay was completed in 1895.
Much of the line closed in October 1992 when all passenger traffic on Jamaica's railways abruptly ceased. Some sections remain in use for bauxite and aluminium freight while the section from Montego Bay to the Appleton Estate remained open for a while as a tourist attraction.
