This token, The World's First Passenger Steam Railway, Invicta 150, was issued by the Canterbury & Whitstable Railway Company to commemorate the 150th Anniversary of the opening of the “Crab and Winkle Line” in the county of Kent, England, on 3 May 1830. 
 
The initial Act of Parliament authorizing the construction of the railway was passed on 10 June 1825, and it took five years to complete.  This line, although contestable, has been claimed to be the "first railway in Britain".  In 1834, the company, however, did issue the world's first season ticket to take Canterbury passengers to the Whitstable beaches for the summer season. 
 
On the reverse, we see the first passenger being romantically alluded to Queen Victoria, but she was only eleven years old in 1830, not yet crowned queen. 
 
Nevertheless, this token does mark the start of the “Railway Mania” which stretched from the 1830s until the end of Victoria’s reign in 1901, when over 1100 million passengers were using trains.
