The Doha Metro project, costing US$36 billion, was completed in phases. The subway will have four lines, red, green, gold and blue.
The Metro project, which is part of Qatar's National Vision 2030 and the overall transport plan, is expected to provide transportation for tens of thousands of tourists to Doha for the 2022 FIFA World Cup.
Now the green line of the metro project is expected to be completed three months ahead of schedule.
Various high-end TRUEMAX equipment, such as concrete towing pump, concrete mixing truck, flat-panel trailer, etc., have participated in the construction of the subway project. There are about 50 TRUEMAX equipment in the mountain top tunnel.
