I'm not sure about how Wikipedia has chose to deal with the "Russia-Ukraine crisis" aftermaths, but otherwise I'm pretty sure the way followed in this article isn't the right one. Listing the Crimean trolleybus systems as they were indisputably Russian, when over an half of World countries defines "illegal" the annexation, is IMHO non compliant with Wiki rules and customs. I think it'd be wiser leaving things "as they were" (just like the "twin article" List of town tramway systems in Russia is doing) until the whole Crimean matter will be internationally settled; or (second best) adding an explanatory section about those trolleybus system, where's clearly pointed out that the fact they belong to Russia is questioned.
Anyway, Crimean Federal District no longer exists: it was abolished and merged into the Southern Federal District on 28 July 2016. 188.8.131.52 (talk) 19:45, 20 April 2017 (UTC)
