Peel are not running rapid-transit rail into Wirral Waters. Yet is is simple and easy to do.
On the surface it appears the Birkenhead Dock Branch Line appears impractical as it runs south in a deep cutting from the docks 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 very short section of new tunnel. Or a cutting through the demolished Mollington Street train maintenance depot. Light-rail trains can be used to reduce the arc of the U line. 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 if need be.
In the picture below, the green is Birkenhead Central station. The yellow line is the existing Merseyrail Wirral Line to Chester and Ellesmere Port. The red is a new line running along the Birkenhead Dock Branch cutting to Wirral Waters from Birkenhead Central station and from Chester in the south. This gives essential rapid-transit access to Liverpool city centre and Liverpool John Lennon Airport.

Birkenhead Dock Branch Line Cutting Ideal for Tunnel Conversion
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 creating a 4 track wide tunnel. Provision for a station could be created in the tunnel for future use. The whole cutting can be backfilled using the now massive trench as a lucrative landfill site. The resulting land may be sold off and developments built upon. Then Birkenhead is rid of a deep ugly gorge through its centre, and the profit from Landfill and land creation set against the cost of re-instating the line.
Me thinks they are not serious at all. Put the station at Wirral Waters and they will come.
