The multi-level train station is very interesting to build. With escalators, elevators, large lobbies, good signage, and children's play areas. There are a lot of staff. The train station is worthy of imitation.
But there are two interesting features: there is no public transport to the airport; taxis (Yandex) do not approach the train station - you need to walk 100 meters in order to get in a car. Due to the lack of competition, bomb drivers are asking for an increased (approximately double) price. This is motivated by the fact that you have to pay for entry / exit from the station. Taxi drivers are (extremely) polite and friendly. They are negotiable and some share information.
For reference: from Nurly Zhol to Astana-1 railway station and bus station, you can take bus 14, 48
