Ploiesti, Romania
R.A.T.P. (Regia Autonoma de Transport Ploiesti)
Neoplan N6121
Unidentified Neoplan trolleybus... it looks like a prototype of some kind (I believe that they tested some battery bus and they burned the batteries and the bus' roof). If you have any information about his "life story", please write me an e-mail.
This trolleybus was under repair (they were installing air conditioning system and electronic display system)... it's possible to be put in service soon.

Starting from August 12th, 2010, the trolleybus fleet of R.A.T.P. is richer with 26 Neoplan N6121 trolleybuses, bought second hand from Lausanne (Switzerland). All have Mercedes Diesel engine, they are 100% low-floor and have been equipped with air conditionig system for the passengers. They kept the same fleet numbers that they used in Lausanne.
More pictures with them in the first day in service can be seen in this page.
