ScotRail was the first part of British Rail to introduce the Class 158s to public service in September 1990.
These were employed on Glasgow Queen Street to Edinburgh Waverley services, as well as services to Aberdeen and Inverness.
The Class 158s then went on to be deployed elsewhere in Britain, primarily in the Midlands, Northern England, Wales and the South West.

With the majority of the fleet coming under the control of the Regional Railways division, the Class 158s became a mainstay of secondary express services between provincial towns and cities.
 Examples included long-distance Trans-Pennine services in the north of England, as well as a range of upgraded regional services under the Alphaline brand in the Midlands, Wales and the South West.

A small batch of units numbered 158747-158751 were used by InterCity to supplement its core fleet on some cross-country services, mainly from the North West to Scotland, but also to Portsmouth.
Units regularly appeared on off-peak workings between Birmingham and Manchester, and also on Sunday mornings between Birmingham and Doncaster.
