IBM railway station (formerly known as IBM Halt) is a currently disused railway station on the Inverclyde Line, 25+1⁄2 miles (41 km) west of Glasgow Central. Clinging to the south slope of Spango Valley on the Glasgow-Wemyss Bay line, IBM Halt was opened on 9 May 1978 by British Rail to serve what was at that time a thriving IBM computer manufacturing plant, employing over 4,000 people. Originally, the stop was unadvertised and only peak-time services stopped there, but subsequently the station was publicly advertised, and all but one service stopped there. At the time the service was suspended it was served by an hourly service in each direction.
