ElectroLAZ-12

It should be noted some differences between the first prototypes of cars. Among them: very poor heating and ventilation (only two small Windows on each side), the lack of protizaŝemlennâ passengers, a very loud squeak when braking. Most of the flaws fixed in serial models, however, a characteristic Squeak and bad ventilation system still remain the "Achilles ' heel" of the trolleybus. In addition, the prototypes were distinguished from later machines slightly different views of the dashboard, window in the driver's compartment was opened as a passenger car, while sitting in the passenger cabin were not "kovšëvymi".
