Not linked to Apple Maps

Apple Maps suggested this app when I indicated I wanted to trawl by rail to my destination. So I downloaded it and when it launched from Apple Maps, it just showed me the ail map. It didnt actually show me which trains I should take to get to my destination. I expected it to highlight the way for me, not show me another map so I cold find my own way there.
