The British Rail Class 483 trains are special electric trains. They are known as electrical multiple units (EMUs). This means they are powered by electricity and have their own engines. These trains were first built by Metro Cammell in 1938. They were made for the London Underground, where they ran for almost 50 years!
After their long service in London, these trains got a big makeover. Between 1989 and 1992, they were updated at Eastleigh Works. This was so they could be used on the Isle of Wight's Island Line. They replaced even older trains there, the Class 485 and Class 486 units. Those trains were originally built in 1923 for the London Electric Railway.
What are Class 483 Trains?
The Class 483 trains are made up of two cars. Each train can carry 84 passengers in seats. They weigh about 55 tonnes. These trains can reach a top speed of 45 mph. They run on 750 volts of direct current (DC) electricity. This power comes from a third rail system. The trains are kept and maintained at the Ryde depot on the Isle of Wight.
From London to the Isle of Wight
The Class 483 trains started their life deep underground in London. They were part of the London Underground 1938 Stock fleet. After many years of service, they were chosen for a new role. The Island Line on the Isle of Wight needed new trains. The tunnels on this line are very narrow. This meant that only smaller trains, like those from the London Underground, would fit.
The trains were carefully moved from London to the Isle of Wight. They were then refurbished, which means they were repaired and updated. This gave them a new life. They started running on the Island Line in 1989. These trains have become a familiar sight on the island. They have served tourists and locals for many years.
