Recently, we came across a video simulation of passenger movement at a future MRT station for the Cross Island Line (CRL) on a transport consultant's website. Vertix Asia Pacific (VertixAP) is a Singapore-based and home-grown transport consultancy firm that has extensive experience in the Asia Pacific region for transportation projects.

Vertix was hired to conduct simulations of pedestrian (passenger) movements for a stretch of 6 stations along the CRL, which include 3 interchanges with either existing or future lines. When cross referenced with SAA Architect's personnel portfolios[1,2], this corresponds to Contract C1006 for CRL East (Package B).

Based on the known design parameters, we can infer that the station in the simulation is Punggol interchange which connects to the North East Line (NEL). The existing NEL station platform is served by 2 elevators to the north and south concourses located at street level, and separated by Punggol Central. In an earlier published book, it was noted that Punggol station was built with a box for a future connection to the Northshore Line, which has presumably been made part of the CRL.
The positions of the escalators to the lower level also line up with our expectations. Based on the layout, it would appear that the first level shown is Basement 1. This is where the NEL platforms lie in a north-south direction while the CRL concourse is perpendicular to it. As the NEL tracks are at this level, it explains why the CRL concourse cannot be connected to the NEL platform. Thus, this means that the CRL platforms will be located at Basement 2 level. The current NEL Punggol station serves Waterway Point and Punggol bus interchange primarily. In line with the plan to extend the reach of the stations geographically, it seems that the new subways runs lengthwise along Punggol Central before branching out futher to entrances along Punggol Place and Punggol Walk.

In summary, we understand that the CRL station at Punggol would likely use side platforms, the rolling stock will be 8-cars long with 5 doors per side, and that the depot will be located in Changi. Unfortunately, due to copyright issues we are unable to display the Vertix passenger movement simulation video here. Nonetheless, do feel free to head down to Vertix's website where you can view some of their other projects as well.
