the system which collects electric current from the underside of the contact rail, although the latter system may have the slight advantage in safety for personnel compared with the former (Japanese) system. Maintenance will be easier for the Japanese system. In view of these points, the Japanese system is recommended for adoption by Bangalore ELRTS.
(2) Trackwork Special
Cost estimate in Japan for track work special, namely turnouts on main track turnouts on sidings for shuttle service of train and turnouts in Binamangala junction is as given in Table 9,3.3-5.
Equivalent cost converted to cost in Bangalore was estimated in the same way as that for general track work as shown in Table 3.3-6.
Material cost is the cost for procurement of turnouts. Turnouts production cost is composed of material cost manufacturing laboure cost and depreciation cost of manufacturing machine. The distribution of turnout production cost among material, laboure and machine depreciation was roughly assumed as 50:45:5.
(3) Cost for Track Maintenance Equipment
Cost estimate for track maintenance equipments / machines for Phase I is as given in Table 9.3.3-7. Converted cost for Bangalore is estimated as US$ 2,553,606.
It is assumed that one large depot equipped with major machines will be located in Binnamangala Depot and other two small depots will be located at the suitable locations along the Phase I route. Such equipments as hand tie tampe1 electric generator will be provided to each depot (one in Binnamangala and two small depots in other locations).
