Dubai has become synonymous with transition, and this is immediately apparent when you see the innumerable pillars of the Dubai Metro, straddling roads and springing up beside major highways and between landmarks. This metro is unique in its scale and the way that it is being threaded into the confines of the city’s existing infrastructure. Robin Lyndhurst reports.

section of the Red Line have been designed to reflect the modern me- tropolis, with distinctive curved and shell-shaped roofs evoking the city’s pearl diving heritage. The elevated stations are elliptical in shape, with the principal design philosophy being to wrap the station around the tracks. Daytime temperatures average 39 de- grees Celsius in August, and so the ques- tion of getting to and from the metro is particularly important for passengers. The stations will be air-conditioned, and RTA says covered walkways and air-conditioned footbridges incorpo- rating travelators will be provided, with step-free access throughout. All platforms will have screen doors, to save energy and ensure safety. The stations will have dedicated car parks, and integrated links taking passengers to buses, taxis and abras (traditional water taxis). Bus feeder routes serving air-conditioned stops will be organised to help commuters plan their travel, while park and ride facilities at Rashidiya and Jumeirah Island will each have 3,000 parking spaces.
