The journey between Jebel Ali and Al Furjan takes about six minutes and frequency will be 10 minutes at a rate of six trains per hour, with the route serving 4,176 riders per hour per direction. From Jebel Ali I can change to the main line and access the Marina, Mall of the Emirates, Dubai Mall and the Airport within 10-40 minutes, or 5 mins towards Abu Dhabi for Ibn Battuta Mall. I can also access bus routes from the metro stations to the malls, medical centres, beauty salons, supermarkets as well as the beach, tourist attractions, the canal and ferry terminals and Old Dubai, the Creek and the Souks. Pretty much ALL of Dubai.
I prefer travelling by public transport, you see so much more interesting places to just stop off at get a great view of the ever changing city, meet some interesting people and best of all, it costs less than £1 to travel the length of the line in one go.
