There are conflicting signs as to whether or not the defective vehicle(s) have moved - nothing else seems to have, not eastbound, anyway. The 0520 Liverpool - Newcastle is now showing as having been terminated at Newton-le-Willows, and any reference to it having reached Parkside Junction deleted from tracking. Whether it actually reached there, I don't know.
One thing which has surprised me is that the 0715 Ellesmere Port to Leeds has been allowed to reach Newton-le-Willows, someone must have been confident that the blockage was about to be cleared.
