Gulliver U520 Esp (zebra batteries)
• Since year 2005 drivers and passengers starts to strongly ask to Atac to haveair conditioned cars; for this reason and due to high age reached (around 10 years service), Atac starts to imagine a new electric vehicle generation.
• Atac was asked in 2007 from Rome Municipality to study how to improuvequantity and quality of historical center pubblic transportation and the choicewas a new full electric generation lines (up to 7 lines)
• In year 2008 a new contract was fixed between Tecnobus and Atac based on 100 vehicles delivery and 5 years full service.
• The old Gulliver generation substitution has been completed (50 deliveries at april 2010) and is now ongoing the improuving of the electric fleet with 3new electric lines (completion within beginning of year 2011).

Failure analysis
• Many drivers calls for failures are to be solved by telephone (incomplete training of
new product on 6.500 drivers)
• The most of “real” failures is connected with doors (many people try to force) and
batteries + engine control software (sometimes quick reset necessary)
• Other buses common failures (pneumatic, mechanics, springs, gear boxes, incoming
water, etc.) are not present.
• All failures are normally solved during batteries recharging time (except damages
on external body) and Tecnobus people is well organized on a three shifts base with
original spare parts available

Conclusions
The new Gulliver generation is judged from Rome users a real good product for
heavvy public transportation in the historical center. Atac and customers are very
satisfied mainly because of :
- high level of confort (width, air conditioning, engine, informations, ticketing,
electric platform)
- improuved daily battery life (12 hours or 130 km with air conditioning)
- indipendent driver cabin (driver door)
- improuved maintenability
- low recurring costs
- high quality of Tecnobus personnel from technical and management point of view
