Just a heads-up that there is an engineering block Crewe - Stockport overnight Monday 28/10 to Thursday 31/10 affecting all lines.
In particular - as far as this thread is concerned - the 2232 Manchester Piccadilly - Shrewsbury is a bus from Stockport to Crewe.

By Diagram, the 67 + Mk 4s which works 1W65 1855 Cardiff - Manchester forms 5K65 2230 Manchester Piccadilly - Crewe CS which runs via Warrington BQ for route retention purposes. However most nights it actually forms 1J76 the 2232 Manchester Piccadilly - Shrewsbury as far as Crewe, where the train is normally restarted as a class 197. Obviously that will not be the case with the engineering block on. It's just a shame that the ECS via Warrington isn't being used as a passenger service, as an alternative to having to leave Manchester much earlier then get a bus from Stockport to Crewe.
