 In 1996 , the work to establish a financing package for new investments in public transport in Akershus and Oslo started . Oslo Package 2 was passed in 2001 and allowed municipal and state grants to be supplemented by increased fare and toll road revenue to finance , among other things , new trains for the metro . The initial order by Oslo Sporveier in 2003 from Siemens was for 33 units ( 99 cars ) , plus options for further orders . In 2005 , the city council voted to replace all existing T1000 and T1300 stock with the MX3000 , increasing the quantity by another 30 units . Two test units were delivered in October 2005 , with the first serial deliveries in April 2007 . With the delivery of the new white and gray trains , Oslo Sporveier received criticism that they had been disloyal to the old red color of the metro , and that they did not follow up on their former design concept from the 1960s through the 1980s . Following the 2006 decision to convert the Kolsås Line to metro standard , Akershus County Municipality announced they would order five units .
