W. Alexander & Sons

An early gain was the Scottish General Omnibus Group, which, through a northern subsidiary, took the growing Alexanders empire as far away as Aberdeen and Inverness by 1930.

[7] In 1934 another notable achievement was an agreement with Perth Corporation to run city bus services on their behalf.

[3] Some acquired companies were initially operated as subsidiaries rather than being immediately absorbed by Alexander, notably General Motor Carrying Co. Ltd. of Kirkcaldy (1930–37),[8] Simpson's and Forrester's Ltd. of Dunfermline (1929–38),[8] Pitlochry Motor Services Ltd. of Pitlochry (1929–42)[9] and David Lawson Ltd. of Kirkintilloch (1936–61).

[9][3] In addition to running services, Alexanders had also been building bus bodies since 1924, initially for their own use and then for their subsidiary operators and other members of the SMT group.

[3] The geographical extent of the company's services was huge, extending from Glasgow and Oban in the south west to Aberdeen and Forres in the north-east, so for management purposes there where three operating areas - Fife (within the county of Fife, which prior to the construction of the Forth and Tay road bridges had a relatively self-contained bus network), Southern (south and west of Perth) and Northern (Dundee and the north east).
