URA draft master plan 2019 - CRL1 details shown

This past week, the Urban Redevelopment Authority (URA) unveiled the Draft Master Plan 2019 with updated maps of the country. Included in the updates to the maps are the alignment and station outlines of the Cross Island Line stage 1 (CRL1). These show several unique features of the line.

The first station along CRL1 is Aviation Park. Due to its proximity to the Changi East depot, this station becomes a diverging point for the main line and depot reception tracks. As a result, it appears that the station will be designed with 4 tracks serving it, although it is likely that two of these tracks may not be used for revenue operations. Noticeable are the cross overs on both sides of the station - to the west between the main line tracks and the outer tracks and another between both bounds of the main line & to the east again between the main line tracks and outer tracks. Looking at the arrangement of tracks and spacing between, it appears that this station may consist of 2 island platforms. 

Additionally on the eastern side beyond the station, the tracks can be seen turning towards the yet-announced Terminal 5 station. On the western end, one can see the tunnels which undercross the existing Changi Airport which run closer together than at other locations - this is set to be one of the two points that utilise a single large diameter bore for tunnel construction instead of the usual two regular diameter bores for each bound.

Pre-construction - Teck Ghee

As one of the earliest awarded contracts for station construction, it is likely that works at Teck Ghee station will commence earlier than other station sites along the Cross Island Line stage 1 (CRL1). Now a quiet neighbourhood along Ang Mo Kio Avenue 6, the dual carriageway road will soon make way for heavy construction of both the MRT station and upcoming North South Expressway.
