The trolley buses (trolley buses) of the type ZiU-11 ( Russian ЗиУ-11 , in German transcription Siu-11 ) were from 1972 to 1973 in Uritzky plant ( Завод имени Урицкого / Zavod imeni Urizkowo), today trolza (Тролза), in Engels (initially the Soviet Union , now Russia ). The ZiU-11 is a variant of the ZiU-9 with a shortened car body.
The ZiU-5 , the Soviet standard trolleybus built since 1959, had already been available since 1966 with the ZiU-7, a variant with a shortened car body to meet the needs of lines with less traffic. Although this was unsuccessful and did not go into series production, a shortened version was already planned as the successor to the ZiU-5 when the ZiU-9 was planned, which, however, like the ZiU-9, was to have three doors.
Based on the prototype of the ZiU-9 from 1970, the planning of the ZiU-11 began in 1971. The car body was shortened by a window field between the first and second door, which made the body about a meter shorter. The number of seats was reduced from 32 to 22. 1972 two prototypes were produced. The type designation ZiU-11 from the planning phase was changed to ZiU-681 ( Russian ЗиУ-681 ), but this designation did not prevail for this type. The prototypes corresponded to the first series of the ZiU-9B / ZiU-682B with a narrow bead on the roof transition and ventilation openings at the top of the front. In 1973, five series vehicles were built that corresponded to the ZiU-9B / ZiU-682B (without a bead, but still with angular wheel cutouts) that were built at the same time. The testing of the prototypes continued until 1974, but had no consequences because the ZiU-11 was deleted from production planning in favor of the ZiU-9.
The ZiU-11 were deployed in Cheboksary and Volgograd , but the exact distribution between the operations cannot be verified. The ZiU-11 were taken out of service by the end of the 1980s; none of them survived.
