I can remember those old platform canopys just about still being there in the early 80s along with a lot of rubbish strewn down the grassy bank. The old platform on the left of the photo (you cant see it because the train is in the way)was removed in the early 90s I think.
you must remember the surviving platform was widened some time ago so the track layout is not the same as it was! i remember the old platform that still had the old signs and ironwork in situ when it was demolished (1990's??) if i recall, parts of the ironwork etc were saved for the wirral transport museum that WAS going to be in the Cheshire Lines Building! unfortunately that never took off
