the current R211 propulsion used in MTR isn't actually an R211 propulsion but rather an S-train propulsion which confused me when i first heard it and still does til this day, so why not get the real deal via asking YouTubers if you're allowed to use it like: https://www.youtube.com/watch?v=DkN0jE-LI0s&ab_channel=TJRailfan ? [you don't have to do this but if you do then it would be nice not gonna lie]
