Conclusions7.9.15 At the projected populations for Ma On Shan for 1996 and 2001, patronageestimates for a light rail system linking Ma On Shan to Tai Wai are sufficient to justifyserious consideration <strong>of</strong> this project. However, volumes would be approaching thecapacity <strong>of</strong> a light rail system as currently envisaged. Also, bus services can handlethe passenger transport without much problem.7.9.16 <strong>The</strong> economic evaluation indicates poor returns on this project, both in financial andeconomic terms, which indicates a low priority. This is mainiy because <strong>of</strong> therelatively low average journey speed <strong>of</strong> the line as noted above resulting in lowoperating benefits over buses. Strong competition from buses operating in parallelto the light rail line adversely affects the financial viability <strong>of</strong> this project.7.9.17 <strong>The</strong> Ma On Shan LRT system would be enhanced if extended to Diamond Hill. Thisproject is looked at in the next section.7.10 Diamond Hill Light Rail Line7.10.1 This project comprises a light rail line connecting the KCR station <strong>of</strong> Tai Wai (theterminus <strong>of</strong> the possible Ma On Shan LRT) with the MTR station at Diamond Hill.<strong>The</strong> project would have the characteristics <strong>of</strong> an urban link, with just oneintermediate station at Tsz Wan Shan, and an average journey speed <strong>of</strong> 55 km/h.With the Ma On Shan LRT system completed, through trains could be run from MaOn Shan to Diamond Hill.Patronage Projections7.10.2 Passenger volumes on this line depend on whether or not the Ma On Shan LRTline is in operation. Thus the following volumes are projected (in thousands <strong>of</strong>passengers'per day);1996 2001With Ma On Shan Line 135 172Without Ma On Shan Line 87 111Service and Capacity7.10.3 As noted in the previous section, 4-car trains running at 2 minute headways wereassumed to match the proposed Ma On Shan LRT service. <strong>The</strong> 2001 projectedpatronage in this situation would be at the design capacity <strong>of</strong> an inter-urban LRT,although still short <strong>of</strong> an acceptable normal capacity.7.10.4 <strong>The</strong> patronage estimates reported here assume that the LRT would operate as astand-alone system with no fare integration with other rail modes. If fare integrationwere in operation, or if Ma On Shan population were to grow much beyond thecurrently projected 2001 population, the capacity <strong>of</strong> the Diamond Hill LRT couldbe exceeded. Capacity would also be exceeded if the East Kowloon Line wereconstructed south <strong>of</strong> Diamond Hill since this project would channel passenger flowsinto the Diamond Hill-Sha Tin corridor.Financial/Economic Evaluation7.10.5 As an extension <strong>of</strong> the Ma On Shan LRT system, the Diamond Hill LRT shows goodfinancial returns by 2001. However, a drop in revenue on the KCR main line wouldmodify these results overall for a KCRC-run light rail operation. <strong>The</strong> economicevaluation also shows good results for this line, with a HIGH rating at 2001 whetherwith full time savings or counting just one third <strong>of</strong> time savings, and dropping toMEDIUM only in the case <strong>of</strong> taking one third <strong>of</strong> time savings in 1996.140
