Far North Line anyone? Can't think of anywhere else in Scotland 158s run, except possibly the Dundee line.
Edinburgh/Glasgow to Perth Perth to Inverness Perth to Dundee Edinburgh to Dundee via Kirkcaldy Dundee to Aberdeen Inverness to Kyle of Lochalsh Inverness to Wick and Thirsk Inverness to Aberdeen Fife Circle Line (Edinburgh - Kirkcaldy - Glenrothes - Edinburgh) Borders Railway (Edinburgh - Tweedbank) Maryhill Line (Glasgow Queen Street - Anniesland) Shotts line pre-eletrification (Glasgow Central - Edinburgh Waverley) That's all the lines the scotrail class 158 runs on off the top of my head.
