There are no metre gauge railways of any significance in this country.
The DLR uses lots of docklands abandoned railway viaducts so it was
presumably thought to be simpler to stick to standard gauge which seems
to handle the curves without problems.

The trains handle the curves but they really don't sound happy about it
especially on the west india key to westferry curve. There's a huge
amount of squealing and shuddering even at single digit speeds. I
suspect its really on the limit of curve radius you can have with
standard gauge track.

Metre gauge trains aren't immune to this problem either.

No, but the dragging effect of the outside wheel moving over the rail faster
than its turning (and similarly the opposite for the inside wheel) is lessened
because of the reduced distance between the rails.
