The Lazio regional government of has just completed a survey of the eight main commuter railway routes to the capital run by Trenitalia. Eight hundred local trains carry 300,000 passengers a day and the survey found that 70 per cent of these trains run late although usually only by a few minutes. The trains were found to be moderately clean with lighting, with air conditioning and heating that functions 58 per cent of the time. Passengers complained about a lack of information when trains were running late and about the slowness of the journey, particularly on the routes that are single track such as the Rome-Tivoli line where it can take 46 minutes to cover the first 20 km from Rome to Guidonia. The number of people travelling into the city by train is increasing with many rush hour trains running at 100 per cent capacity or more.
