maybe, I was just in Switzerland and people said that Japan is even better in terms of transit. If Singapore has reliable prioritized public transport, then yep, it's cool. What shocked me the most is that in Swiss, all tickets for any transport can be bought in a single app, and if you don't want extra hassle, you don't even need to buy it, just press a button and the app will calculate by gps what you need to pay. This + super precise arrival times...
Literally the 2nd item on your list is C651 made by Siemens which has design and headquarters in Munich, Germany.
Also a quick Kagi search could have pointed you at "Siemens Mobility awarded contract to deliver CBTC on Singapore’s 8th & longest fully-underground MRT Cross Island Line" ;)
Okay I give you that. I was wrong about zero. 19 trainsets out of a total of 594. 3%. And those were manufactured in Austria (like I said), not Germany. But yes Siemens is HQed in Munich. So I guess they bought them from there. True.
Not sure how one can interpret "Singapore because they buy their excellent MRT trains from Germany" and then those excellent trains are a mere 3% of Singapore's trains (with the vast majority being Chinese and Japanese. Even the French trains are more than 3x as many). But hey, whatever.
