Steepest light rail/tram gradient?

[Chapeltom]

I've always been interested to know where the steepest gradient is on the light rail/tram networks around the country.

One to start off with, between Shalesmoor and University on the Sheffield Supertram network, that feels steep, especially when crammed full of football fans.

Quite a few steep sections on the DLR especially by the triangle by poplar/ west India quay

We have the Queens Head viaduct on Midland Metro although I don't know the actual gradient - it's steep enough to be an issue if one traction motor failed though....

The DLR has some steep sections in particular where it drops into the Bank tunnel and around Poplar. The Croydon tram link has some impressive gradients in the Addington hills and through Croydon high st. The steepest tram gradients I have been on are in Lisbon and the odd system in Trieste. In Trieste the tram runs by adhesion on some impressive gradients until one very steep hill where it is pushed up by a cable hauled wedge shaped vehicle.

Leaving Nunnery Square on Supertram heading to Meadowhall, turning left - seems to be quite steep from memory.

Sheffield Supertram has gradients of 1 in 10.

The Metrolink between street level and Deansgate. Also between Cornbrook(?) and the back streets of Salford.

Beamish I believe has the steepest gradient used by heritage trams, if not trams in general, of 1:16 up Pockerley Bank - the maximum permitted by HMRI when the line was built.

Blackpool's Gynn Hill is around 1:30 and certainly not as steep as many seem to think (Steeper than Pockerley Bank is often floated...). Indeed Crich Tramway Museum's 'extension' (It was opened in the late 70s, but it's still the extension) is 1:30 also at its steepest point.
