Trams are so late 70ish. Sydney has refrained from intensifying its tram network. They have resorted to increase bus frequency and added new routes. Trams are an eyesore. (Melbourne and New Mexico). Either way it will make a dent on the traffic network since it has to run on the already bottleneck ridden 2 to 3 lane carriageways. Take heed and enlarge like abudhabi. They need 4 to 5 laners here. This alongwith better bus services and skytrains will lend a new lease of life to qatar congested traffic scene
