After the First World War the line was electrified using a third rail on the seaward side of the single track line. Second-hand locomotives from the Avon Mustard Gas Factory were purchased and brought into use in 1922.

At the pier entrance there are two short non-electrified sidings, one of which leads into the coach shed.

The line is operated throughout the year and the trains connect with all the ferry sailings to and from Southampton. There is only one train in service at any one time

The first three images below were taken in the summer of 2005 and show the Pier Train after a new lick of paint! You can see how the train used to look in its red and white livery below -these images were supplied by permission of Lars F. Richter and tramway.com
