various West Country destinations, resulting in the use of InterCity 125s on the route. At this time, the service operated on a half-hourly frequency with all trains stopping at Haymarket and Falkirk High, with alternate trains stopping at Polmont and Linlithgow. Some peak hour trains stopped at Bishopbriggs, Lenzie and Croy. Sunday trains served . In 1984 the Polmont rail accident, where a train hit a cow on the track (part of the cow's leg was trapped in the bogie of the train, lifting it off the track) resulted in 13 deaths and 61 injuries. It led to a debate about the safety of push-pull trains. In the late 1980s with the electrification of the Great Eastern Main Line by British Rail, the DBSO set-up was planned for replacement with Class 158 in four and six car formations, however due to delays in deliveries and the need to release the stock for the Great Eastern Main Line, Class 156 were used for a short period, prior to being put into use on the Far North Line. 1990s/2000s Delivery of the Class 170s since 1999 has displaced the Class 158s for other duties, including the Far North Line. Other motive power can be seen as a result of operational considerations including Classes 156 and 158. Present day Since electrification of the line in 2017, services have been operated by s from July 2018. Since October 2018 HSTs have been introduced on long-distance services that use parts of the route.
