It's been a while since I frequently travelled to or through Uppsala.
Since then, the train and bus station is rebuilt and it is really really nice.
Especially to travel by bus has been easier - all buses transfer here.
It is easy to find your way to the buses or trains.
On the downside: finding a ticket machine for the UL buses/trains is not easy. There are 2 or 3 - one of them at Kungsgatan (stop A2). You cannot buy tickets on the buses going out of town.
TiM-machine (Trafik i Mälardalen) is found under the trains tracks in the tunnel and at track 8.
AMEX is not accepted in machine nor at the staffed desk. read more
