The LOR was multifaceted to say the least. At its northern end, it connected with the Lancashire and Yorkshire and ran specials to Aintree on Grand National Day. After running along the docks, with the dock lines weaving below it, it crossed the Cheshire Lines Committee main line to their terminus at Central Station, as well as the Herculaneum Goods station, and then plunged into the cliff face to become an underground railway to its southern terminus at Dingle. You can still see the tunnel entrance today.
I just remembered, the LOR also crossed the LNWR line from Edge Hill to Riverside Station, alongside the Pierhead, where boat trains took the liner passengers. Almost another main line!
