IBM railway station (formerly known as IBM Halt) is a railway station on the Inverclyde Line, 25½ miles (41 km) west of Glasgow Central. Clinging to the south slope of Spango Valley on the Glasgow-Wemyss Bay line, IBM Halt opened on 9 May 1978 by British Rail to serve what was at that time a thriving computer manufacturing plant employing over 4,000 people. Originally, the stop was unadvertised and only peak time services stopped there, but now, despite the decline in the fortunes and working population of the plant, the facility is publicly advertised and all but one service make the stop.
