- Animats 4y agoI got that info reading about a dual-gauge solution for China's Belt and Road. But it was a political piece on the "Akhaura-Sylhet dual gauge project" in Bangladesh. Turns out that India, Pakistan, western Bangladesh, and Sri Lanka (also, SF's BART) use 1,676 mm gauge. There's enough space between that and 1,435 mm standard gauge for 3-rail. Not sure about 4-rail.
- justsomehnguy 4y agoSee my other comment[0] on this. 4-rail is a viable solution, but, unsurprisingly, it costs more than a 3-rail or sometimes a two separate 2-rail lines. [0] https://news.ycombinator.com/item?id=31880979 https://news.ycombinator.com/item?id=31880979
