Following a three month delay, trams started running from Birmingham New Street Station yesterday Saturday 30th May.Centro's Midland Metro extension from Snow Hill travels via Corporation Street to Wolverhampton.
Construction of the 0.7 mile (1.2km) track extension was halted over the busy Christmas period and was due to be completed in February.
When the delays of the track were announced, Phil Hewitt, from Centro's Midland Metro, said: "A stringent testing programme has identified minor anomalies in some of the track alignment which need to be addressed".
Jonathan Cheetham, from Retail Birmingham, said the tram system "gives us huge credibility as a city".
"Investors from abroad, which we've seen a lot of recently, know and understand how important transport is," he added.
The service is planned to expand routes to Edgbaston and Centenary Square
