Please can we have class 197 or 175 and 67 hauling Mark 4 coaches, for Manchester Airport Commuter. All of them run or used to run Manchester Piccadilly to Cardiff Central and West Wales. 150s were only used apparently for shortages. They would call at Manchester Piccadilly, Stockport, Wimslow and a very limited service at Alderney Edge. 197: 175: Also has a 3 car variant. 67:
