Pingyao old town to high speed the GuCheng train station by public bus

Hi there,

Just after a little advice if anyone has any. We need to get from PY(within the ancient town walls) to the new high speed train station PY GuCheng.

I've read on this site that there is a public bus from PY to the new train station, also that the buses may be red or purple? And fare cost 3RMB one way.

Does anyone have any additional information?

Do these buses depart from the PY bus station (near North gate) or the train station?

Are these buses regular? E.g. 12noon on a Monday is ok?

How do we know what bus it is? Number/colour?

How long does the bus take?

How much is the fare?

Thanks in advance for any help all, just trying to fill in the blanks. Hopefully this will help others in the future too.

Bests, Steve
