was built between 1972 and 1977, and since 1977 trains from James Street have travelled round the loop calling at , and a new platform at Liverpool Central before returning to James Street. The original two platforms at Liverpool Central were reused as part of the Northern Line. The tunnel and railway are still in use today as part of the Wirral Line of the Merseyrail commuter rail network. Shore Road Pumping Station in Birkenhead was a museum until closure sometime before 2014. Georges Dock Pumping Station on Mann Island in Liverpool is a grade II listed building. Rolling stock Steam locomotives For the opening of the line, eight powerful 0-6-4 tank locomotives were obtained from Beyer, Peacock and Company, fitted with condensing apparatus for working in the tunnel. Designated as Class I, a ninth followed within six months. Beyer Peacock also built six 2-6-2T tank locomotives in 1887 (Class II) and three further 2-6-2T (Class III) were built by Kitson and Company in 1892. The 0-6-4Ts were built with steam and vacuum brakes and steam reversing gear and weighed . The 2-6-2Ts were fitted with vacuum brakes only; those built by Beyer weighed and Kitson's . As electrification progressed, the old rolling stock was advertised for sale. An attempt to sell the 18 locomotives and 96 carriages by auction in June 1903 proved unsuccessful – the auctioneer had to remind the bidders that he was not selling scrap. It was September before the first locomotive was sold; it would take another two years to sell all-bar-one of the locomotives. The last locomotive — which had been retained for working permanent way trains — was sold in January 1908. The first to be sold was No. 5 Cecil Raikes, which was bought by Shipley Collieries for £750. They came back and bought No. 8 for £650; but not before Alexandra (Newport and South Wales) Docks and Railway had bought all six of the Class II locomotives for £3,450. They became ADR 6–11 (not in order). Alexandra Docks later bought four more locomotives: Three 0-6-4T (Nos. 2, 3 and 6), and one Class III 2-6-2T (No. 16), these becoming 24–22 and 25. All ten ADR locomotives passed to the Great Western Railway in January 1922, and were withdrawn between January 1923 and May 1932. The other two Class III locomotives were bought by Whitwood Colliery for £1,240. The last four locomotives
