JR East Aims to Open New Haneda Airport Line in FY 2031

According to The Jiji News, East Japan Railway Co. , or JR East, said Tuesday that it now aims to open a new train line connecting JR Tokyo Station and the Japanese capital's Haneda Airport in fiscal 2031, two years later than the initially planned fiscal 2029. 
The new line will allow passengers to travel between the station and the airport without changing trains in around 18 minutes, compared with about 30 minutes on existing lines.
Construction for the new airport line will begin in earnest in June. In the 12.4-kilometer section between the airport and an area near JR Tamachi Station, a tunnel will be built while existing facilities such as elevated tracks will be renovated.
