Read the destination signs carefully. Some trains on this line make short turns.
The Hankai Tramway runs small trams through the southern parts of Osaka. While they may not be useful to the tourist, their terminus is located within walking distance of Tsutenkaku Tower.
The Shinkansen runs very frequent service from Osaka to Tokyo and points west. They stop at segregated platforms at Shin-Osaka station, so a Shinkansen ticket is needed to spot and photograph these trains.
