Dear Sirs!

Having found your site I was interested very much. Thank you for the information you give! Buy your data on Ukraine are far to being full. So I am giving you the correct list of the ETB cities. As the cities of Ukraine are known in the world under the Russian versions of their names I give those versions after the Ukrainian ones. No one of the trolleybus systems has not been closed, so I give only the year of opening. Different sources give different dates of opening that is why I give you only the years. The fleet in many systems is in the process of changing so the data I give are of 2000.

                                                                                           Hresivsky (Simferopol Airport).      
Zaporizzhia           Zaporozhye          1949                  ZIU 9, ZIU 10, YUMZ T1, YUMZ T2.    
Zhytomyr              Zhitomir               1962                  ZIU 9, YUMZ T1.

*Although one route from Donetsk leads to Makiyivka, it does not reach the routes of Makiyivka. There was a linking line between the two systems in 1980ths but it never came in a revenue service and now is removed.
** There is also the city of Dzerzhinsk in Russia and it also has a trolleybus service.
*** The route systems of Simferopol, Yalta and Alushta are interconnected with the interurban routes run together by all of the three cities and the whole service is under the united administration. But each of these cities has its own numeration of the urban and suburban routes. The interurban and suburban routes have never been separated from the urban ones neither physically or in their administration nor in their numeration which has never doubled. The same is about all the systems in the former Soviet Union countries. 
**** In 1959 the interurban line from Simferopol to Alushta opened. In 1962 Alushta received its own depot and its own first route. The inner urban route appeared there in 1993.

In Vyshevychi a trolleybus line was under construction but it came to nil. Two Kyiv 11u vehicles were received and five more ordered but one of the received ones later came to Chernivtsi and the other was scrapped, the ordered ones came to Kremenchuk.

Now the systems are under construction in Kerch, Melitopol, Kamyanets-Podilsky, Krasny Luch and Kolomya.

And some more details about some other countries. In Azerbaijan there are two more operating systems you do not mention: Sumgayit (since 1962) and Mingecaur (since 1989). In Uzbekistan Dzhizakh and Zhiazakh are the transcriptions of the same city’s name. In Lithuania the years of opening you give are wrong, really they are Vilnius 1956 and Kaunas 1965. The same is about Estonia: Tallinn 1965.
