Right. I was in Crewe and needed to go to a meeting in Cheadle Hulme. Day Return to Cheadle Hulme. Simple. Well, journey planner gave a fastest journey via Stockport (at that particular time), so presumably my Cheadle Hulme ticket would be valid via Stockport. Correct? But since I might be returning from Stockport I decided to buy a Crewe - Stockport ticket. Travelled Crewe to Stockport. Block on at the subway, nodded me through. Went over to p.1 and caught my connection to Cheadle Hulme. When my meeting finished there was a long wait for a train at Cheadle Hulme so I caught a bus to Stockport (three trains an hour to Crewe). And as I stepped onto the train I suddenly thought, "am I being naughty here?" Was my outward ticket to Stockport valid for travel to Cheadle Hulme, via Stockport? Or had I, effectively, already used the Stockport - Cheadle Hulme part of my return ticket? I can see a case both ways. Any comments?
