MISC | Sharpest Subway Curve

I'm interested to hear what people consider as the sharpest subway curve that they have come across!

It's got to be on a system with small short cars. Maybe a VAL line in France somewhere. The Miami Metromover or Singapore LRT branches?

Or maybe the Chicago El? That has 90 foot radius curves. Other light rail systems around the country make similar tight moves.

I think the Oedo line has some pretty significant curves if I remember correctly.

The ones I can find statistics on, however, are the Central Line on the London underground that has a curve radii of 61m between Shepherd's bush and White City.

It would be good if photo and/or video could be posted to support your claim.

The claim to be one of the sharpest subway curves in the world.

Omg, this is so childish Come on, it's 2016, Happy New Year!

Anyway, I believe some of the sharper curves can be found in cities with older networks, like London, Paris or Berlin. But I don't have any stats, either.

Happy new year:

Berlin: 74 m on U2 between Wittenbergplatz and Zoo, others with 50 m are situated in depots or in the so called Klostertunnel to link lines 2,5 and 8, which does not count. I would only consider sharp curves with passenger-service.

Hamburgs sharpest curve is about 71 m radius at the Rathaus U3-ramp. I don´t know about Stadtbahn-tunnels in Cologne (Ebertplatz). Basically Stadtbahn surface-sections sometimes derive from former tramway, so I would not take them into account.


Kind regards

Paris metro
Line 1: Bastille 38m (I did not include the 32m curve of the reverse loop at Porte Dauphine on line 2 because it is outside passengers service).

Paris metro has plenty of sharp curves.
You just have to look at the route of some lines to understand.

I would say the Chicago CTA has one of the sharpest curves, especially downtown in the loop. The subway cars are much shorter than most other subway systems around the world because longer cars would not fit around the sharp curves.

Grand Central subway 1918



This map was published in the July 27, 1918 issue of Scientific American, showing the plan for the Grand Central subway station.
