Introduced into service in 1977, the iconic InterCity125 High Speed Trains have been a mainstay of some of our fastest railway lines for well over 40 years, with their streamlined styling blazing a trail across the UK. Now as the end of their reign in front line express passenger service approaches we take a look back at these historic trains, which have helped to shape modern high speed travel on the UK railways, from their design and introduction, through to their colorful post-privatization lives and their rundown from front line services. Undoubtedly a very successful design, time is now running out for the InterCity HSTs and we pay tribute to this British railway success story.
