According to Hyperdia there is a train that departs Nagano at 10.29 for Yudanaka. It stops at Shinshunakuna 11.15 and departs from here at 11.25 for Yudanaka.
Is the train to Yudanaka on a separate line and if so where is this line in relation to track 2 at Nagano station?
Do I change trains at Shinshunakuna or stay on the same train?
This trip will be in October.
