The British Rail Class 303 electric multiple units also known as Blue Train units were introduced in 1960 for the electrification of the North Clyde and the Cathcart Circle lines in Strathclyde. They were initially classified as AM3 units before the introduction of the TOPS classification system and were the dominant EMU on the Glasgow suburban railway network for over 25 years before being progressively phased out by newer rolling stock.
