The Jurong Region Line (JRL) is a rapid transit line being developed to serve the Jurong area and surrounding districts. In a notable H-shape, the line features several branches that link it to various districts. Based on the LTA definition for MRT and LRT systems, we assume that the JRL will be classified as an MRT line. LTA defines an LRT system as one that transports under 10,000 people per direction per hour (ppdph). Whereas an MRT system is one that transports over 10,000 ppdph. As such, this indicates that the distinction between systems lies in the passenger capacity rather than the mode (rubber-tyred or steel-wheeled).
In order to expedite the construction of the line, we believe that it will be an elevated line running with rubber tyres. This allows a quieter operation which can be brought along major roads close to residential areas. The LRT-like operation of the line could also allow more flexibility. An example of what we envision to be a similar system is the Yurikamome line in Japan which features a Mitsubishi Crystal Mover stock with 6 cars forming a single train. The flexibility of such a system is that it allows the capacity for branches with a more seasonal demand to be adjusted accordingly.
One branch of the JRL is intended to reach the Nanyang Technological University. This branch would see a more seasonal demand for service as the university has its teaching terms and holidays. This could lead to the over-provision of capacity if a fixed capacity system is used, typically that of the steel-wheeled, steel-railed train variety (current MRT lines). A rubber-tyred, concrete-track system allows flexibility with passenger cabins that are connected together as needed. For instance, the MIA Mover in Miami has Mitsubishi Crystal Mover cars in married pairs. Such a configuration could be joined into 4-car or 6-car formations as needed by the passenger demand.
We expect that the branches with higher demand would be the Choa Chu Kang and West Coast branches as these connect to existing estates with high passenger traffic. The creation of additional and alternative routes would allow the crowds to ease from the congestion present on the current routes available.
