RAIL TUNNEL IN ROCK SPEEDS B.C. TRAINS

The article describes the construction of the 4568 Ft. long, 16 ft. wide and 24 ft. 6 in. high railway tunnel being blasted through cranite-like granodiorite rock at Nelson Creek, West Vancouver, Canada. If the preliminary rock survey, showing solid, uniform rock formation is correct, no steel lining and only occasional concrete grouting will be necessary. /TRRL/
