Is it possible to start and finish tour at the railway station (we should be at Xian at 8: 31 + 1)?

We can pick you up from the railway station, but time is too tight for you to catch the bus tour if you arrive at Xian at 08:31, let alone that the train often delays. Moreover, you are not able to do any afternoon sightseeing if your train leaves at 15:52 the same day. In this case, we kindly suggest you consider taking a private half day trip to the Terracotta Army if you can not change your trains.
