The LRT project is scheduled to be completed in 2012 and it is 40 KMs of track .Sounds like good news but can anyone explain why a LRT project for just one city is going to take 15yrs to complete??? Maybe its not going to be 15yrs of continous construction i.e. the phases will be added as the city grows:?
Most subways and LRTs are done in phases and montreal is a good explain of that with a decades long plan . The metro there was started in the early 60's and was still being constructed in the 1980's . the extension of the subway to the olympic park was in the 1974 to 1976 time frame or nearly 15 years after teh start of montreals subway.
you might think going above ground if easier but it of course presents its own problems of crossing developed lands in many cases or making the land suitable for a rail bed.
all that said julius berger nigeria had constructed 80 km of high quality railway in nigeria with concrete high speed rail ties in about a year for a mining project. cutting a rial line without a an urban landscape is different then putting a spur line thru rural areas without passenger stations is another.
