Passenger transport was of two types; trains that corresponded with the ferries and connected with trains at Tinnoset, and commuter trains transporting workers to the plants at Rjukan. The commuter trains were initiated in 1913, and Norsk Hydro started building housing at Ingolfsland and Tveito, and both Ingolfsland and Miland got their own stops, and from 1919 stations. The two kilometers (one mile) commuter train from Rjukan to Ingofsland took five minutes; a month pass cost NOK 2.50 for employees and their families. There were seventeen departures in each direction per week, timed to fit with the working times at the plant. This increased to 58 in 1916, when a new stop at Tveito was opened.
