If you are in Delhi and need info on Delhi Metro routes, look no further than Google Maps. The information is available in the Transit layer in Google Maps. To see this layer, simply click on “More…” button in the maps area and then select the “Transit” option.
Google maps will also tell you if there are any metro routes available when you are searching for directions. Click here to see an example for directions from Noida city center to New Delhi Railway Station where Google maps suggests you the metro routes available. Of course you have to select the “By public transit” option in the drop down for this to work.
