Before the taxi era emerged in Leamington spa:

Before the evolution of Taxis & Private hire vehicles service, people in Leamington spa and the whole of UK used to travel on old hackney carriages pulled by a single horse, it made journey cheaper, faster and light enough to be pulled by a single horse. This has been used historically in London when taxi service had not emerged. Later in 1897 electric battery powered taxis became available at the end of 19th century. Walter C Bersey designed a fleet of such cabs and introduced them to the streets of London. These electric battery powered taxis were also called as hummingbirds due to the humming noise they made.
