Really short time at Xian

Hi guys,

I'm going to arrive at 西安火车站 around 13:00 and I'm planning going straight to see the warriors, by bus I saw that takes about two hours, so I would have something about three hours to see the museum then return in the last bus, at 19:00, Is it possible? I mean, arriving and then see the site at the same day? It's because I'll just stay one day, heading to Beijing next day at 19:30, in the same train station. Thanks in advance for any tip guys, I have a really short time!!!! 😃😃😃😃
