Dubai Metro has resumed operations after two glitches suspended service on the Red Line late on Thursday. Commuters faced delays between Union Square and Business Bay stations and Emirates Towers Station in two separate incidents. But the service was back online late on Thursday night. Transport authorities laid on bus services to help people affected and thanked them for their patience. About 1.5 billion passengers have used the service since it opened 10 years ago. Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai, inaugurated Dubai Metro in 2009. It was introduced to ease rapidly worsening traffic congestion. The red line opened first and two years later, the green line followed. Today it is a vital part of the emirate's public transport system.
