Hi, Tony,
Greetings!
Thanks a lot for your questions.
There are definitely 2 buses from Xian downtown to the Terracotta Warriors. This is the most economy way from Xian to visit Terracotta Warriors.
The Buses are,
Bus No 914 Xian Railway Station-Terracotta Warrior
Bus No306(游5)Xian Railway Station-Terracotta Warrior.
It is easy to find the buses at the East side of the Square of Railway Station. The bus fare is RMB7 per way per person. It takes around 1.5 hours to arrive the Terracotta Warrior.
When you arrive there, you could buy entrance tickets on your own. If hope to know more about the Terracotta Warrior, you could also rent a guide service at the entrance.
Hope the above is clear and helpful.
If you have any more questions, just contact with us.
Best regards
