August 12 celebrated the 39th anniversary of Prague’s A-Line. To commemorate the event, the metro is deploying the historic metro tram, the 81-71 series. The 81-71 series was specially designed to conquer steep sections of track, like those found on the A-Line.
Although the A-Line’s celebration lasted just one day, its original run from 1978-2009, meaning the trip was conducted for 31 years. The Soviet-made 81-71 series was nicknamed the briquette by its operating staff. Briquette is a coal-based fuel, condensed into a block-like shape.
