a bit of recent history - in 1991 or 1992, soon after Ukraine independence a "train of friendship" - a train loaded with several hundreds of Western Ukrainian ultra-nationalists (many wearing insignia and uniforms of OUN-UPA - Ukraine nationalistic organizations which collaborated with Nazi and committed genocide of Polish and Jewish populations in Volyn region in order to make it majority Ukrainian territory) tried to come to Sevastopol. Combined police and Russian Navy forces blocked the train from coming into the city . Small group of the nationalists made their way into Sevastopol by boats, yet being mostly non-armed and outnumbered they could do nothing.

Things were different in 2014 when volunteer battalions of such nationalists were organized under the cover provided by the Ministry of Interior Affairs and thus were legally armed, and "the trains and buses of friendship" were about to go to Crimea and Eastern Ukraine. Well, they did still go to Eastern Ukraine while the Crimeans got lucky that Putin decided that it will boost his rating.
