One thing mr.Farrukh Saleem is missing is the quality and the mix of expensive-to-build track to total track
For example, here is an example of Ahmedabad brts
In phase II just adding 4.5KM elevated track to otherwise half of the track equates the cost of both tracks.
Delhi also incurred high cost because of elevated and underground sections
Ahmadabad only has around 5% of the route elevated vs ~40% of Islamabad Metro bus. Plus it also seems that they haven't spent a lot on building other infrastructure as well
Compare this with Istanbul Metro
What i would be interested is how much percent of the track of all the metros is elevated/underground.

If we compare Islamabad and Ahmadabad thenTo date, the Ahmedabad BRTS has completed 66 km. Another 22 km is due for completion, taking the total cost to Rs 1,000 crore. Experts say an overland or elevated section of the Delhi Metro cost on an average Rs 100 crore per km. Underground costs were higher at Rs 475 crore per km. Taking the least average construction cost of Rs 100 crore per km, if a metro train system had replaced the BRTS in Ahmedabad, the city would have spent Rs 8,800 crore (Rs 100 crore X 88 km) for the 88-km system.
