Birkenhead Town to left - original Grange Lane to right (later Abacus Works) - looks like the flyovers are being started in the foreground.
I suspect the original Grange Lane station to be the building with the damaged roof and advertising billboard on it, and not the Aabacas works.
Can anyone clarify this?
I can’t clarify with proof, but I can certainly muddy the waters further!
Personally, I believe the Abacus building to be the original Grange Lane terminus - the building with the holes in roof just looks, well, so mundane for a prestigious terminus station in the new up-and-coming town of Birkenhead. This railway was the wonder of the age, and making a statement was what the Victorians loved - I don’t think that single storey building would have impressed the investors or punters. The ‘Abacus’ building might have done, and looks to be in period for 1840.
Grange Lane station only operated as such from September 1840 to May 1844, (when it was closed as a passenger station and traffic re-routed to Monks Ferry), but it’s position would have been right at the end of a dead-straight approach – why would it kink slightly to the right to the lowly building at the end of the approach?
1845 map crop attached.
Looking at the Abacus building – imagine it without the saw-tooth roofed engineering works behind it, and then imagine it with a light and airy double span roof instead, all cast iron columns and girders. Now note that the ‘Abacus’ building conveniently has a double gabled roof, one for each train shed roof to butt up to (the hipped roof at the front of the building masks this feature from the road, but the aerial gives it away).
In this guise, you get the single track approaching a delicate looking train shed with the stone built ‘Abacus’ building right behind it. Much more like a typical terminus station of the period, probably with 2 platform faces in the centre, and loco-servicing spurs. Possibly a small goods yard where that single-storey building is too.
I've attached a crude photo edit to show what I mean.
I reckon the saw-tooth building was added once the station closed to passengers, and partly covered what had been the station precincts. It looks far more purposed for engineering than passengers.
All just my opinion - just need to find more proof!
