Travelling over the flyover to Liverpool today and the road leading to the booths - sorry don't know name of approach rd. On the right I noticed a derelict double fronted wall with a door! Typical I didn't have my phone to take a quick picture - I was a passenger!
I'm curious what was there and why leave the front of a building!
All these years and I've never noticed it before! Has anyone noticed this before and any ideas?
Thanks

Remains of Grange Lane Station.
It is usually covered by an advertising hoarding.

I remember it being owned by AABACUS in the fifties who made cranes but never realised it was an old station.

I strongly suspect that building was neither Grange Lane Station nor Town station, it would appear to be the offices for the railway engineering works behind it.

I suspect it wasn't either.
I reckon it is the Aabacas building. You can see the wall with the curve on it is clearly the same as the Aabacas building, by comparing this picture with the screen grab below.

Here is the screen grab of what I think is Grange Lane and Birkenhead Town stations.

If any of these help, 1900, 1911, 1938, Directories

That 1938 one has Aabacas on the corner.
The pic above is from 1963 so they must have moved.

Not on the corner, just first numbered in that stretch from Tunnel Rd.

I didn't realise the sheds were divided between the railway works and Aabacus, I thought Aabacus just had the yard beside them. Not having a foundry chimney I didn't think of them having an enclosed works, plus there are trainlines going into the Aabacus sheds .... but it all makes sense now.

Directories are often incomplete, sometimes some streets only appear to have three addresses when physically there were a lot more premises.

I agree. Here is a photo from 'Railway Stations of Wirral' in the 'Yesterday's Wirral' series (Ian Boumphrey). The resemblance to Rock Ferry Station is obvious.
There's more on 'Disused Stations' website. One shows the slope from this building down to the platform.

I can vaguely remember a weather vane of an outline of Stephenson's Rocket on the Aabacas building, seen from the top deck of my 50 or 58 bus as it stopped outside Sturla's shop. Many years ago!

Birkenhead Town to left - original Grange Lane to right (later Abacus Works) - looks like the flyovers are being started in the foreground.

This one bri? Not 'Rocket' though - more likely a L+M 'Planet' or similar.
