Off the Rails: A Love Story S01 E12 The Grande Finale

Marcus gets to ride the one train that's eluded him until now. He heads for Northland via Helensville where he meets the women who used to run the station tearoom. He explains the world of "foamers" - railway obsessives who have crossed the line - and goes as far north as the rail ever went. Finally, Marcus walks the line - literally - to Opua.
