The Changi Airport Skytrain is an automated people mover (APM) that connects Terminals 1, 2 and 3 at Singapore Changi Airport. Opened in 1990, it was the first driverless and automated system of its kind in South East Asia. The Changi Airport Skytrain operates from 05:00 to 02:30 daily. Traveling on the Skytrain is free and an inter-terminal journey takes approximately four minutes. Since 2006, the trains operating on all Skytrain lines are Crystal Movers manufactured by Mitsubishi Heavy Industries. All stations are equipped with platform screen doors, are air-conditioned and have plasma displays indicating the arrival time of the next train. With the opening of Changi Airport MRT station on 8 February 2002, the Skytrain is able to connect passengers at Terminal 1 to the MRT station entrances located at Terminals 2 and 3. History In November 1990, alongside the opening of Changi Airport's second passenger terminal, the Skytrain began operations to connect the brand new Terminal 2 to the existing Terminal 1. It operated using the Adtranz C-100 and the ride lasted approximately 60 seconds. On 17 March 2006, the rolling stock was replaced with the current Mitsubishi Crystal Mover System. Services were extended to the newly opened Terminal 3 and the South section opened in November 2007 with 5 new stations. On 24 February 2015, services between Station B and E (Terminal 2 to 3 and vice versa) were suspended to make way for the construction of Jewel Changi Airport. The service was reopened to transit passengers on 12 April 2019, upon the opening of Jewel Changi Airport using a 3-car service. It was then fully reopened for the public and transit passengers in July 2019. In April 2020, due to the COVID-19 pandemic drastically reducing passenger volumes, services from Station B to E (T2 to T3) and Station A to F (T2 to T3) were suspended for all passengers, as well as Station B to C (T3 to T1) and Station D to E (T1 to T2) services for transit passengers. All Skytrain services were then fully suspended on 1 May 2020. On 27 July 2020, services from Station B to C (T3 to T1) were resumed for public passengers only. On 17 November 2022, services from Station B to E (T3 to T2) were resumed for public passengers only.
