The northern approach to Aberdeen is squeezed between Union Terrace Gardens and a dual carriageway, Denburn Road. There's still room for a double track line but despite the reinstatement of the second line further out and the recent introduction of more frequent services between Aberdeen and Inverurie, the section between Berryden Junction and Aberdeen remains single. 158716 and 158731 approached Aberdeen with 2B22, the 09:56 from Inverurie, on 11 April 2023. The leading unit would continue to Montrose, leaving the trailing unit behind at Aberdeen.
