I´m back, and i present the CO Haneda Int. Airport

Simutrans 102.2.1 + Pak128.japan+ Japanese Addons + Airport set of Pak128 (because of the lack of airport addons on pak128.japan)
Its an Artificial Island Airport, in the middle of the sea, conceted by 1 subway line (wako shinsen line)(the city has 22 lines in total), 1 frecuent bus route(to dowtown, Twin Towers Station(10 subway lines), And CO Ekimae(conected to shinkansen and 5 subway lines)), also its conected by a tunnel to the National Highway System.
The airport isn´t so popular, beacuse of the huge metro/subway/commuter rail system, and for long distance routes there is a shinkansen high speed rail network.
