<p>月台 （建筑样式） 编辑 讨论
在古时建筑上，正房、正殿突出连着前阶的平台叫“月台”，月台是该建筑物的基础，也是它的组成部分。由于此类平台宽敞而通透，一般前无遮拦，故是看月亮的好地方，也就成了赏月之台。而现代的月台通常指进入火车站后方便旅客上火车的一段与火车车门踏步平行的平台。</p>

Thanks! The *moon-watching platform* etymology sounds reasonable.

NS.X.
<p>On a recent trip to Taiwan, I noticed that the MRT platforms there are labelled 月台 (yuetai / yuètái). Asking a professional tour guide (Taiwanese local, native Chinese speaker) only revealed that he'd never been asked that question, but he didn't have an answer for me.</p>

<p>Googling around, I found the following synonym: zhàntái ( 站台 ) <a href="https://dictionary.hantrainerpro.com/chinese-english/translation-yuetai_platform.htm" rel="nofollow noreferrer">- Han trainer dictionary</a>, which sounds more understandable (platform for standing). However, I don't see any connection between MRT platforms and months or moons. There doesn't seem to even be a link to shape, as the platforms are straight. (The 'queue-up' lines drawn on the ground are often L-shaped - that's closer to a moon shape.)</p>

@user6065 No. It just refers to the moon. 月台 just means "moon-watching platform", and later extends its meaning to any platforms.

None of the references is very authoritative, but all of the search results agree with each other, that 月台 for 'railway platform' is an extended meaning from its original meaning 'moon-watching balcony' which refers to a platform that protrudes from a building.
