Plans for Abu Dhabi's subway network project were changed, drastically shortening the length of the line. While the length of the line was thought to be 130 km in the initial plans, it was decided to change the line to 70 km.
The 18 km first phase of the line will be ready by 2020 at the latest, within the scope of new plans. It is planned that the vehicles will speed up to 40 km / h, 100 km / h underground.
In addition, two 40 km tram lines will be included in the transportation plan by 2018. The tram will run at an average speed of 20 km / h.
