Buxton to Warrington (Arpley) - ex-LNWR lines: Marple was on the GC Macclesfield line. I think 48188 was an Arpley loco, although John Axon was based at Edgeley, and presumably took it on from there to work to Buxton & back and hand it back to its Warrington crew.

And I think the other train might have been from Rowsley (not Rosely) to Stockport (Edgeley). The collision actually happened in the station at Chapel-en-le-Frith
