I had a quick look at the bit of Todmorden curve you can see from the footbridge.

No.1 The left fork goes to Hebden Bridge and the right will eventually go into Todmorden station and onwards to Manchester.

No.3 Looking back towards Burnley, they have installed a switch over to get the trains onto the other line so they can go into Tod station.
I think that once the Home tunnel re-alignment is finished trains will be able to run through from Accrington to York again even though the curve may not be finished.
It looks to me as though the work on the track they use to York is completed, the switch overs are complete and the cables to the points and signals are in place.
