To transport Buran from the space center Baikonur to the launch pad they used rails with a powerfull locomotive. The first and only launch of Buran took place in November 1988. The flight was unmanned, controlled only by computers. The split of the Soviet Union resulted in a cash strapped space program, which left the Buran stranded on the ground, rusting away. My sources say that they managed to build two out of planned five. They had planned to launch the shuttle only 3-4 times a year in addition to the 100 rocket launches usually made. Unlike the American shuttle the Buran was only going to be used for missions which could not be done by other craft. These missions included repair missions and return of old satellites which could not be done by the small Soyuz spacecraft, it was also going to be launched to dock with the current Mir station to deliver crew and supplies and bringing home scientific material. If their shuttle program had not been stranded they had planned to send the old space station Saljut 7 which had been boosted to a higher orbit until they could find out what they wanted to do with it back to Earth. The station was not going to be used again but to teach us what 10 years in space had done to it.
The rocket is currently not in use because all of the satellites launched are relatively small and only require a small rocket like a Proton to boost into orbit. When the Russian space program was still going strong they had planned to use the Energia to boost a new space station into orbit
(Mir2) consisting of several modules each weighing 100 tons. The current Mir only consist of modules weighing 20 tons and the ISS will also consist of modules weighing 20 tons because that is the maximum weight the Proton rocket can carry and the shuttle can launch when it has to reach the inclination and height of the new station. Transport of people to the new Russian station was also going to be made by Buran with the Soyuz only acting as a rescue vehicle but as you probably have noticed those plans were scraped because of lack of funds.
