I think that t-bus Solaris Trollino 12T is better than Skoda 21Tr because in may 2000 this czech's low-floor trolley was tested in our city. When our local politics and president of Gdynia were going this trolley, Skoda brokedown. Ingeener from Skoda said (sorry, but I don't know czech's language-I don't rememer it very good) "Spilcua pofistka pocitace".
