There is indeed, so Merseyrail trains are certainly signalled towards a semaphore signal (although the electrification stops before they can reach it?).In that photo of Ellesmere port I think I can see another semaphore in the distance on the left just before the road over bridge part covered by tree branches .
It’s not all that many years (six or seven?) since Hooton signal box closed, and the section between there and Ellesmere Port was Absolute Block before that, which presumably explains the change in training for drivers?
