Why is "Birkenhead Dock Branch" trending?

Wikipedia Overview

Birkenhead Dock Branch is a disused railway line running from the South junction of Rock Ferry, to the site of the former Bidston Dock on the Wirral Peninsula, England. The branch is approximately 4+1⁄2 miles (7.2 km) in length. Although called a branch, the line was accessible from both ends, from Bidston East junction and from Rock Ferry railway station. The former Mollington Street Rail Depot was branched into the line. A section of the line runs through Haymarket Tunnel and a low-level cutting through the centre of Birkenhead; visible from the road flyovers. The former Canning Street North signal box has now been demolished following fire damage, and the rails across the level crossing there have been removed due to the provision of cycle lanes on the roadway. The non-standard gates remain on the east side, but a fence has been erected on the other side despite the railway being officially out of use, rather than closed. Level crossings are also located at Duke Street and Wallasey Bridge Road. The railway lines are still partially intact.
