arose from shorter trains and larger intervals, but in particular from the transfer at Ulitsa Starokachalovskaya/Bulvar Dmitriya Donskogo, where the light metro station consists of two separated platforms on either side of the main line with no reversal sidings behind it. As a result, passengers must queue for lengthier times at a platform and also deal with exiting traffic before boarding their train. Additional problems arose from the landscape damage done by the flyover bridge. Furthermore, costly and embarrassing improvements had to be made just a few months after opening. First, improvements had to be made to the faulty new trains, as they required immediate and unforeseen refits; in addition, despite the sound barriers, further noise reduction works had to be carried out on the tracks themselves by repairing their joints. Despite the criticism, the Moscow Metro continues to put forward several expansion programs for the BLLM, the first one of which is to place proper reversal sidings north of the station thus separating the terminus platforms into northbound and southbound roles; at present this is announced for 2010. After the completion of that there was initially a planned northwestwards underground extension towards the terminus of the Kaluzhsko–Rizhskaya line, Novoyasenevskaya with two new stations: Lesoparkovaya and Bittsevsky Park, which opened on February 27, 2014. Since then Moscow Metro has postponed the project and even taken it off its list of primarily projects to be completed by 2015. A further three-station expansion to the southeast, as Butovo continues to grow, is proposed: Ulitsa Staropotapovskaya, Ulitsa Ostafyevskaya and Novokuryanovo, along with a new depot. The latter's construction might prove pivotal as it would allow for the line to become more independent in operation. On the map of new plans, the extension to Milizeysky poselok (or East Sherbinka) is planned with at least two stations. A transfer at Buninskaya Alleya to the Sokolnicheskaya line is planned after 2023. The problems with the Butovo line have also affected the prospect of other light metro lines in general as the second planned line, the Solntsevskaya light metro line, has now been canceled. Its construction was planned to begin in 2004, with the line expected to open in 2006, but after repeated postponements, Moscow Metro decided that it would be more practical to revert to an older project – a conventional, Kalininsko–Solntsevskaya line. After the SL's cancellation, there have been concerns that BL's fate could be
