Budapest's metro system consists of four lines, each marked by its own colour code. This train is of the yellow
line M1. It is a very old metro line and due to its very narrow and low tunnels, it requires also very special trains. M1 is the oldest
metro line in Budapest and it opened for service already in 1896. These trains are so called Ganz MFAV trains. They were built by
Ganz-Mavag in Hungary in 1971-73. Two further trains were made in 1987. It is a three coach train running on normal gauge 1435 mm rails
with a top speed of only 50 km/h (originally 60 km/h). Picture of a M1 line train 15.1.2018 by Ilpo Ruissalo.
