Operated by A-Train AB, the trip takes 20 minutes and runs four to six times per hour using seven X3 electric multiple units . The services operate over the East Coast Line and the Arlanda Line and call at Stockholm Central Station, Arlanda North Station and Arlanda South Station . The service was used by 2.7 million passengers in 2007 and by 3.3 million passengers in 2012 . </P> <P> Planning of the airport link started in the 1980s . In 1993 the Government of Sweden issued a tender for a public--private partnership (PPP) to build the Arlanda Line . The construction of the line was subsidized with a combination of some state grants and large state loans . The successful tenderer would receive a monopoly on traffic between the airport and Stockholm until 2040 . The line and the services were inaugurated on 25 November 1999 . The PPP contract has since been criticized for being unclear, uneconomical for the state and leading to a low utilization of the service . </P>
