For a list of smaller trams as per length or less than that proposed for Bath see  https://bathtrams.uk/appendix-list-131-trams-systems-approximately-route-length-proposed-bath-report/

The graphic above is of the 67km Belgian Coastal Tram serving numerous towns smaller than Bath

Below are small towns on the Belgian coastal tram. In the UK, with Radstock and  Bath connected to Bristol  they would be in a similar situation. Similarly, New Addington and Beckenham below, each with a low population is connected to Croydon with a population of 350,000 plus.

Adinkerke  – 10,060 – Belgian coastal tram

Nieuport –  11,062 – Belgian coastal tram

Ostende – 70,994 – Belgian coastal tram

Blankenberge – 19,897 – Belgian coastal tram

Knokke – 34,063 – Belgian coastal tram

The smallest tram in the world we could find is the Volk’s Electric Railway at 1.02km built in 1883. It serves only a small part of Brighton and is soon to be extended.  It is not of course a true urban tram but this shows how people enjoy traveling on rail for its own sake.

List of small towns and cities of a similar size or smaller than Bath ( (100,00 pop):

The below list is by no means exhaustive – as in the Belgian Coastal Tram example above, many outlying towns are connected to trams but are not listed here as it is mainly the central city listed.
