What's happening to the 323s operating the Manchester Airport (and Crewe Via Manchester airport) services? Why have they so often been replaced with 142s or 150s recently?? Today, I saw a 150 on the Picadilly-Crewe via Stockport too! Is this just while they're having their interior refresh? And are services to Hadfield/Glossop similarly afflicted? Also, have Northern inherited some of FGWs 142s? I saw one with pink highlights and dynamic lines on the seats recently.
