Dehli metro is very nice,
As for Pakistani cities here are the details:
LAHORE:
Lahore will get a Monorail, 34Km long which will cost 30bn rupees (it will be built on BOT basis so the Govt. will not have to pay anything), the contract is expected to be awarded very soon.
Karachi:
Contract was awarded earlier this year but construction hasnt started because it is proposed to be a MAGLEV system which is very controversial (Lahore also had a proposed MAGLEV system but it was scrapped because Maglev technology is new and its very risky).
New Muree:
New Muree has a Monorail approved. A monorail from Islamabad to New Muree will also be built.
