Simferopol-Yalta is the world's longest - 80 km - and European only
mountain trolleybus system. It was built in 1959-1961 to connect 
Simferopol, the capital of Crimea, with two major recreation cities on 
the coast - Alushta and Yalta.<br>
The first part of the system - suburbian route #1 from Railway Station
of Simferopol to Mariano - was launched on October 7 1959 with 9 MTB-82D
on route (length 8.5 km).<br>
The intercity line from Simferopol to Alushta
(the town on the coast) was launched Nov. 6, 1959 with trolleybuses
Skoda 8Tr. On April 28, 1961 the city trolleybus system in Yalta was 
started on the
city route #1 (length 4.5 km). In July 1961 the 33km-intercity line 
between Alushta and Yalta was
opened.<br>
At present, the system has 3 depots and served by about 400 
trolleybuses. The system uses Skoda 9Tr, Skoda 14Tr and YuMZ T2.09 on 
intercity lines, while city systems are operated by Skoda 9Tr, Skoda 
14Tr, and in Simferopol by Skoda 15Tr, ZiU-6205, and YuMZ T1.
