Track laying cost per track meter is as given in Table 9.3.3-1, which is estimated based on track work in Japan. Rail welding of 15 m rail to LWR is estimated by assuming the adoption of gas pressure welding machine. Expansion joints are assumed to be installed at every 1 km.
Depreciation cost for machines per track meter is as given in Table 9.3.3-1. Conversion to cost in Bangalore was carried out as shown in Table 9.3.3-2.
(i)Rail:
The ratio of the price exported to India against the price in Japan is given as 59.84 US$/93.72 US$ = 0.638
(ii) Sleeper:
Converted from cost in Japan to cost in Bangalore by applying the ratio of 1.07, avenge ratio in Table 9.2.1-2,bcsause PC sleeper contains aggregate, sand cement and steel.
(iii) Pandrole rail fastening:
Converted from cost in Japan to cost in Bangalore by applying the ratio of 1.5, the ratio for steel material in Table 9.2.1-2.
(iv) Ballast:
Converted from cost in Japan to cost in Bangalore by applying the ratio of 0.26, the ratio for 40 mm aggregate in Table2.1-2.
(V) Laboure:
Converted from cost in Japan to cost in Bangalore by applying the ratio of 0.024, the average ratio in Table 9.2.1.1. Due consideration should be given to Table 9.3.3-3. As indicated in Table 9.3.3-3, conversion cost for Bangalore prepared by simply multiplying 0.024, average laboure cost ratio of Table 9.2.1-1 and 0.9, average machine cost ratio of Table 92.1-7, shows much difference from cost in Bangalore with respect to cost distribution ratio among material, laboure and machine. Major reason for this will be that in India, compared with Japan, much more laboure will be used than machine, because of cheapness and abundancy of laboure. Considering this factor, some modification should be done for conversion from Japanese cost to Indian cost. In view of this factor laboure conversion ratio was multiplied by 3 and machine conversion ratio was multiplied by 0.90. By this modification, modified conversion cost distribution for Bangalore is as given in Table 9.3.3-3.
(vi) Machine:
Depreciation cost for machine was converted from cost in Japan to cost in Bangalore by applying the ratio of 0.99, average ratio in Table 9.2.1-7 and the modification ratio 0.9.
Total track work cost for Phase 1 is US$ 18.82 million.
(b)Contact rail
Cost estimation of contact rail in Japan is as shown in Table 9.3.3-4. Converted cost for Bangalore is also given in Table 9.3.3-4. Total contact rail cost for Phase 1 is US$ 10.901 million.
Japanese system which collects electric current from the upper side of contact rail is cheaper than
