Последний троллейбус (Posledniy trolleybus) (French translation)

Well, let's harvest the fruits. First of all, the translator is presumably a non-native French speaker. He or she used 'prendre à la course' to describe the process of chasing the blue trolley-bus and finally getting into it. A rather swift guy, indeed Then comes this 'Nous prêtent main forte'. As I understand, something is probably odd there, because the main problem is not in the tense used, nor in the object, because it could be a metonymy when he speaks of "us" imaging himself being a part of those who are wrecked. It may be a kind of language subtlety not easily understandable by foreigners. And, slurring over the bird that could be even a woodpecker with the same effect, we end up with the city and the river. Here the problem lies in the following. In Russian 'троллейбус плывет по Москве' could be understood as if the trolley-bus was passing either along the city (number one association) or along the eponymous river (the second allusion) that could darken as well as the city when the night comes, and they can even do this simultaneously (Москва, как река, затухает). That trick couldn't be played in French, though the translator tried to cope with that using this counterintuitive 'la rivière'.
Something like that, if I'm not mistaken...
