Going underground
Almaty Metro was the first underground train system in Kazakhstan. It was officially opened on 1 December
2011 and it quickly became the most popular form of transport in the city.
At first, there were only seven stations: Raiymbek Batyr, Zhibek Zholy, Almaly, Abay, Baikonur, Auezov Theatre
and Alatau. It may be short, but it is comfortable,' says the school teacher Marzhan Rakhimova, who was one
of the first passengers on the metro. Just four years later, two more stations were added (Sayran and
Moskva) and today the metro covers a route of over 11 kilometres. There are plans to build more stations in
the future. When the entire network is complete, there will be three lines and about 45 kilometres of track.
Thousands of people use the metro every day. It is the safest, fastest and most convenient way to get around
the city. “I prefer the metro because it's very reliable. The trains are always on time,' says 14-year-old Yeldos
Bazayev. "The metro is open every day from 6 a.m. until midnight. The best thing is you don't have to wait.
Whenever you arrive at the station, you know the next train leaves in ten minutes.'
Some of the metro stations have a very modern design, others look more traditional. The terminal station
Raiymbek Batyr is a combination of both. There are marble floors and beautiful artwork on the walls,
including a picture of the Kazakh warrior Raiymbek Batyr. The next station, Zhibek Zholy (the Silk Road), is the
busiest in the city. It is famous for the ceramic reliefs created by the artist Gaziz Yeshkenov. You can learn a
lot about the culture, history and geography of Kazakhstan by looking at the reliefs. The Auezov Theatre
station is also stunning with its spacious halls, bright lights and colourful mosaics. Some of the walls are
decorated with plaques showing traditional scenes from the life of the Kazakh people.
'I like all the stations, but my favourite is Balkonur,' says 18-year-old student Tolkyn Sapiyeva.
It's named after the cosmodrome in southern Kazakhstan and it looks a bit like a spaceship. For me a journey
on the Almaty Metro is like a journey through history into a future."
