When I visited Prague I used the city’s metro system extensively to travel around, it was both efficient and quick. But purchasing a ticket for the journey however was possibly the hardest and slowest task I’ve experienced anywhere in the world.
While waiting on the platform by fluke I managed to snap this train as it sped into the station, no special settings just a snap and hope job.
Some stats: the Prague metro carries around 400 million passengers a year makiing it the seventh busiest metro system in Europe. It’s 30 years old and is mostly Russian-built.
