Is this the railway era for the UAE?

Dubai Metro, one of the most prestigious and remarkable achievements of Dubai. The red line opened at the 9th September 2009 (9/9/9), also at the 9th hour of the 9th minute of the 9th second. Now that is what I call a remarkable opening! The green line had opened at 2011. As of April 2014, more than 14 million people had travelled through the metro in one month, making it a very successful alternative travel to avoid traffic jams (well, the train itself is comparatively slow in compared to most countries). While the metro is going so well, Dubai has yet planned for another railway system; this time it's a tram. At the moment it is under construction and is fairly visible for my sights (which resulted in my research) and is supposedly going to be complete by November 2014. Not only that, Abu Dhabi also sets it's sight on two trains that is going to be set up. One being for supply of resources while the other as a metro system. It seems as if the UAE is setting it's goals to become the railway capital of the middle east.
