The International Olympic Committee (IOC) is concerned about delays in transportation projects and venue construction for the 2004 Olympics to be held in Athens, reported the Associated Press.
An IOC progress report cites prolonged delays in building a rail line from downtown Athens to seaside Olympic venues, and a suburban rail system to ease traffic from the airport to the main stadium.
Organizers for the 2004 Games have overcome many delays since being warned by the IOC about the slow pace, said the AP.
Delays in construction of the suburban rail line, due to protests by residents, have forced the IOC to consider contigency plans, such as using fuel engines if power lines are not ready, said the AP.
The IOC delegation begins a three-day visit to the Olympic site on Wednesday.
