Yep – But only specially modified trams used the Neutral Bay line, didn’t they?

Doubtless discussed previously, but what were the steepest adhesion-only grades on the former Sydney tramway system

The steepest adhesion only grade was at Hayes St in Neutral Bay which was 1 in 10 down to the wharf jetty, and required trams with additional braking systems.

There were a number of 1 in 11 and 1 in 12 grades, notably on the Watson's Bay line and on the Young St loop at the Circular Quay end of the Elizabeth St routes. All the steep grades were traversed at very low speeds.

The Darling St Wharf grade was not adhesion only, as there was cable connected counterweight assistance.
