The history of rail transport in Pakistan covers the period beginning in 1858 during the British Raj, when several railway companies began laying track and operating in what is today Pakistan, and ending during the present-day nationalised company under the name of "Pakistan Railways" (initially known as "Western Railways").
 The railway system in Pakistan was originally built as a patchwork of local rail links operated by small private railway companies.
 These included the Scinde Railway, Punjab Railway, Delhi Railway and Indus Steam Flotilla companies.
 In 1870, these 4 companies were amalgamated into the Scinde, Punjab & Delhi Railway company.
 Shortly thereafter, several other railways lines were built including the Indus Valley State Railway, Punjab Northern State Railway, Sind–Sagar Railway, Sind–Pishin State Railway, Trans–Baluchistan Railway and Kandahar State Railway.
 These 6 companies along with the Scinde, Punjab & Delhi Railway company merged together to form the North Western State Railway in 1880.
 In 1947, when Pakistan achieved its independence from Great Britain, the North Western Railway renamed  Western Railways and the railway system underwent reorganisation, some of which proved controversial.
 From the start of 1948, usage of railways increased and the network became profitable.
 Declining passenger numbers and financial losses in the late 1980s to early 1990s prompted the closure of many branch lines and small stations.
 The 1990s saw severe cuts in rail subsidies and mismanagement within the company.
 Due to falling passenger numbers, rail subsidies from the government are necessary to keep the railways financially viable.
