There's a set of photos I have seen in one of the closed Facebook groups which shows the void beyond that wall and the third arch. In a nutshell - nothing much, other than a partly excavated void (named the Dead End Vent Heading) propped up by old sleepers and a couple of brick pillars. But it does suggest that the Victorian planners maybe had something in mind for that third arch. Remember those same planners future proofed the alignment of the CLC lines with the MR, so its not unfeasible to suggest it was a way of future proofing the station.
You wouldn't happen to know which group it was, would you? I'm in a few of the Merseyside rail history Facebook groups, if I knew which one I could go on the hunt.
I have seen a "blueprint" (in so much as such a thing was used back then) of the planned station before it was built, it showed that arch but not where it went. The station itself was planned to be two tracks through the wide tunnel (one of which was a locomotive siding) and one through the narrow one with a single narrow island platform between the single and double tunnels. It's in the Public Registry Office at Kew if I recall, I went there with my Dad as he does family research and just went round looking up random things I was interested in.
