Changi Airport branch line takeover

With the release of the Land Transport Master Plan for 2040, the Land Transport Authority officially unveiled that the Thomson-East Coast Line (TEL) will take over the existing Changi Airport branch line of the East West Line (EWL). As part of the take over, conversion works will need to be done to the existing Changi Airport, Expo & Tanah Merah stations to accommodate the TEL rolling stock's differing dimensions. The current rolling stock used on the EWL features 6-car trains with 4-doorways per side. However, the TEL stock features 4-cars with 5-doorways per side. As such, the platform screen doors and gates will require retrofitting in order for the doorways to align properly.

The works will take some time, with the line take over likely coinciding with the on-going works at Tanah Merah station and the Expo-junction with the existing Changi depot and upcoming East Coast integrated depot.

URA Draft Master Plan 2019 - Extension to Changi Airport

The Urban Redevelopment Authority (URA) launched the Draft Master Plan 2019 (DMP 2019) last month, providing a view of developments to come across the country. As part of the DMP 2019, improvements to various regions were planned and listed out on the URA website for public viewing. Among these regions is Changi, where the upcoming Terminal 5 of the airport is being developed. As part of the plans outlined, improved rapid transit network coverage is one of the key areas being looked into.

Construction progress at T302

As the Land Transport Authority (LTA) recently announced the addition of Founders' Memorial station, it was mentioned that the construction of the new addition would begin in 2019. This statement was misleading as Founders' Memorial station was being partially constructed as an interim facility building as a future, unopened station on the line under contract T302. It was subsequently added that this would be done by converting a planned facility building into an operational station.
