was formed of vehicles 121 and 221. However, since then, a few rearrangements have taken place to the unit formations. In 1996, with the privatisation of British Rail, the Ryde–Shanklin line became the Island Line franchise, which was won by the Stagecoach Group. Services continued to be branded as Island Line Trains. In 1999 three units (001, 003 and 005) were permanently withdrawn from service as surplus to requirements, leaving only six units remaining serviceable. In the early 2000s, the remaining units were overhauled and were repainted into a new livery of blue and yellow with pictures of dinosaurs. From 2007–2008, all units were repainted into their original London Transport red livery (albeit with yellow warning panels on the cab rather than the original red). According to an article in the October 2005 issue of Rail Professional magazine, at that time Island Line was paying "an eye-watering £140,000 a year" to lease the trains, meaning that "[s]ince privatisation, HSBC Rail has pocketed over £1m for leasing these relics that are effectively worthless." In March 2007, South West Trains purchased the rolling stock outright from the leasing company HSBC Rail for £1. Further that year, the Island Line franchise was amalgamated with South West Trains as part of the new South Western franchise. Refurbishment The Class 483 trains were last refurbished during 2007; work on the six-vehicle fleet included: an exterior repaint into London Transport maroon with cream window pillars a retrim of the seat moquette into the same moquette that the London Underground A60/62 Stock received during their refurbishment between 1993–98 When South Western Railway took over the franchise in 2017, it launched a consultation on the future of Island Line services, revealing that only three of the six remaining units were serviceable. Replacement On 13 September 2019, South Western Railway announced that because of a "safety issue" only one of the units was able to run, which meant cancelling just under half of scheduled services and running only an hourly service on the Island Line. This reduction in service was by mid-September expected to last for approximately one month, until 14 October, but the company warned that the trains' age and increasing difficulty of getting spare parts meant it might take longer. Normal service was not restored for approximately 5 weeks, but further fleet faults brought repeated disruption through much of November. Just 3 days after the news that
