It has emerged today that Network Rail have postponed the project to electrify the route from Manchester to York. No new completion date has been set.
The DfT says Network Rail has discovered more work will be needed than was originally proposed.
What effect this will have on the Northwest Sparks area is not clear, but I would guess that Manchester Victoria to Stalybridge and Guide Bridge to Stalybridge are probably under threat. And perhaps also the fourth track through Roby and Huyton.
