Hi,
I think the usual daytime runners through Woodsmoor are the Peak Forest to Hope Street (Salford) and return stone trains, also the evening empties from Ashburys to Dowlow run that way.
If the morning train 6J46 (Peak Forest - Hope St) runs, then the return working will probably be the 6H56, due through Stockport at 16:10 then via Woodsmoor.
On the search linked above for Woodsmoor, 6J46 passed Woodsmoor this morning at 10:03, but it doesn't run every day.
The Ashburys - Dowlow train in the evening is a regular runner Monday to Friday, due through Stockport 19:55, taking the line all the way through to Buxton and on to Dowlow.
If you search on Realtime trains for trains at Ashburys S.S. or Hope St Peakstone P.Sdgs (all day) you can see if the outward workings have run, they should show a time in bold once they've arrived. If you look at Ashburys S.S. and click on the train from Dowlow, it has real time reports (in bold) at Peak Forest, so the return empties should run through Woodsmoor tonight.
