Question

The world's first publicly subscribed passenger railway, the Stockton and Darlington, opened in England with steam engines when?

Answer 1

Wales, UK
The tram was horse-drawn and started running in 1807. This was on the Swansea and Mumbles Railway. The Mumbles Railway Act was passed by the British Parliament in 1804. The railway was worked by steam from 1877, and from 1929 by very large (106-seater) electric tramcars until closed in 1961.
