Metro service in Dubai was started in 2009 and since then it has been a great relief for the daily commuters. Currently there are two lines; Red Line and Green Line. Red Line goes from Dubai International Airport to UAE Exchange and Green Line goes from Etisalat Metro Station to Umm Hurair.
Red Line operates from 05:30 am to midnight on the working days from Saturday to Wednesday and from 05:30 am to 01:00 am on Thursdays and from 10:00 to 01:00 am on Fridays. Green Line is open on all working days from Saturday to Wednesday from 05:50 am to midnight and from 05:50 am to 01:00 am on Thursdays and from 10:00 am to 01:00 on Fridays. Dubaimetro.eu, mydubaimetro.com etc give you the options to download the metro map.
