A Japanese team of consulting engineers recently carried out an on-the-spot study of the proposed underground railway project in Bombay and will submit their report in about three months' time. The survey lasted six weeks which included the test-boring at several places along the proposed route in order to study the sub-soil conditions. The Japanese experts expressed the opinion that the soil conditions in Bombay for constructing an underground railway were very much more favourable than those in Tokyo or Osaka, which would, therefore, result in the reduction of the total cost of the scheme. The cost of the scheme would be Rs. 3 crores per mile of double-track construction, out of which about Rs. 2 crores would be on civil engineering works and Rs. 1 crore on rolling stock and other mechanical and electrical engineering works.
