Intercity Transport is limited to marshrutka’s and shared taxi’s and the journeys on the road are long. Whereas, traveling by train is not only cheaper but also more comfortable and faster. Moreover, crossing the desert becomes fun on an Uzbek train. Indeed, Uzbekistan has a good rail network, and trains are the ideal way to travel between Tashkent, Samarkand, Bokhara, and Khiva.
While you can buy tickets for any Uzbek train service at any train station. Whereas you will need your passport and you pay in SOM. Although at Samarkand, I purchased a ticket and paid with my Visa Credit card. In addition, you can purchase your ticket through their online ticketing system.
Likewise, the most of Central Asia, shared taxis are the best way to get around Uzbekistan. You can get them easily on all the main intercity routes. It includes the congregate at most border points. However, shared taxis leave the stations after getting full. You can find them near bus main stations. Shared Taxis run all day until late afternoon.
On the other hand, you can found very few options for long-distance buses of any kind. I have traveled from Bukhara to Samarkand on a Bus with 50000Som. It took about 4 hours to reach there(Shared Taxi in 3 hours and Fast train in 2 hours). For a shorter distance between towns, you will find 11 to 14 seat Russian-made ‘Gazelle’ vans. For shorter suburban trips you’ll find cramped seven-seat Daewoo Damas minivans.
Transportation within Tashkent. In Tashkent, you have a lot of options like Metro, Buses, Marshrutkas, mini Buses, Shared Taxis, and Yandex taxis. Google map is your best companion to show you the exact route with available transfers and estimated travel fare. Bus/ metro fare for one visit is 1400 Som(15cents).
Yandex taxi and its app is a good option to travel within the cities. In addition, it is most convenient and economical too. Besides, you can get metered/non-metered taxis everywhere in Uzbekistan. Whereas, please confirm the fare before riding to any non-meter taxi. And do it twice for a safer side. However, you can get a taxi within a city for 1~3 $.
