E was suspended due to construction works for Jewel Changi Airport. Passengers in the public area had to use the mezzanine level bridge along Changi Airport MRT station, and the Skytrain operating between Station A and F in the airside. Landside operations for services between stations A and F only resumed in July 2019. Expansion To increase the system capacity of the Skytrain, six new train cars have been purchased which subsequently entered service in 2019. The existing shuttle between Terminals 2 and 3 was upgraded to a three-car system, whereas the shuttle between Terminal 3 and 3 South was upgraded to a two-car system. Terminal 4, opened in 2017, is not served by the Skytrain. However, the future Terminal 5 will also have an underground automated people mover system.
