37611 Pegasus approaches Norton Junction on 2 August 2021 with the 5Q94 10:09 Northampton EMU Depot to Long Marston, conveying Northwestern Railway EMU 350127 for modifications. This caused a massive delay to the following 6Y03 06:46 Eastleigh to Long Marston, as presumably nobody had considered the limited line capacity of the single track Cotswold Line and the Long Marston branch.
