This is a prompt on the ticket machine for the Haruki Train, to Kyoto from Tennoji. ( I could totally be making all these names up and you’d never know!).

It is a single train.   Unless part of the train goes a different speed than another part, this confused us so much.

Being American, we chose the most  ‘loaded’ option, naturally.  Plus we didn’t want to be on the part of the train that went all slow.
