Not long ago I was in Birkenhead near Birkenhead Central station. This station is in a cutting with a tunnel either end of it. Running south the tunnel opens up to Green Lane Merseyrail station. The next station is Rock Ferry. At Rock Ferry the Birkenhead Dock Branch Line (disused since 1993) branches off running north towards Birkenhead Docks, emerging at the eastern end of the docks at Egerton and Morpeth Docks, running through a deep cutting and through the Haymarket tunnel, right through the centre of Birkenhead. This cutting still has lines in it and is overgrown with vegetation.
Over a year ago there was official rumblings of using EU money to re-instate a line to Birkenhead Docks. The docks can be accessed via the Birkenhead Dock Branch Line or via Bidston at the western end of the docks.
Wirral Waters proposal will use the eastern docks of Vittoria Dock and East Float. The western dock, the West Float will still be commercial shipping. It makes sense to access the docks via Bidston in the west and not via the Birkenhead Dock Branch Line to the east, coming in from the south.
That is quite simple and pretty logical for freight traffic. However, how do you get a Merseyrail passenger line to the East Float and Wirral Waters - essential for it to become a success? The Birkenhead Dock Branch Line appears impractical as it runs back to Rock Ferry and only accessed via the south. However the tunnel directly south of Birkenhead Central station running around the gas holders can be branched into and curved into the Birkenhead Dock Branch Line. This would be a short section of new tunnel. Or raise up and onto the now demolished Mollington Street train maintenance depot. Then Merseyrail trains from Liverpool would run through Hamilton Square, Birkenhead Central and then do a U-turn and turn north onto the Birkenhead Dock Branch Line and onto Wirral Waters. A station could be built in the cutting at a suitable point. Sorted for little outlay.
However the Birkenhead Dock Branch Line cuts right through Birkenhead centre. Such a deep cutting is a hindrance through a town centre. Precast concrete arches can be used to cover the line making a 4 track tunnel. A station can be left in the tunnel. The whole cutting can be backfilled using the now massive trench as a landfill site which is lucrative these days. The resulting land can then be sold off and developments built upon. Then Birkenhead is rid of a deep ugly gorge through its centre.
Sounds a like a win, win to me.

Birkenhead Central station is to the west of the round gas holders bottom right - right next to them. The dotted lines are the Merseyrail track running south to Rock Ferry and the Birkenhead Dock Branch Line running south to Rock Ferry. The solid red is the Birkenhead Dock Branch Line running through the cutting and tunnel to Birkenhead Docks and Wirral waters to the north. The solid red curve to the south of Birkenhead Central station would be a short tunnel length.

The deep railway cutting can be clearly seen running through central Birkenhead. The green line, bottom left.
Parts of the Lime Street cutting from Edge Hill to Lime street could be made back into a tunnel. That cutting is a nuisance creating ugly blank brick walls. along its length. Buildings could be built over various parts of it. A part of the university was built over a section.
