I don't know if you have noticed this, but at 3:39 two of the cars of the Type U are colored gray inside, instead of the usual orange, the rest of the cars are all orange as you can see. --> --> Finding the gray cars is hard, they are normally seen on the U2 and these are the only 2 in existence, this makes this sighting even rarer due to this being the line U3 and the video (as of writing this comment) being only 2 years old. I dont really have an explanation as to why there are just randomly 2 gray Type U cars in the system, as they are not really found on RU-vid besides being featured in 3 videos, i myself have seen them but they are mostly loaded with passengers, unlike in this video. The 3 Videos that DO feature them say that this was a marketing strategy of the Wiener Linien when they were introducing the newer (at the time) Type V cars. Besides being gray, the 2 rare cars feature red seats made from what seems like plastic which may actually be the same seat type as the ones from the Type V cars and they feature different lighting types (one is more yellow than the other) which is fairly noticeable with the gray interior. Anyways It's cool to have noticed this, especially on the U3 line. Good video, like the ambience. Keep up the work! ❤
