Cable Car Track Brakes
The cable cars of San Francisco are fitted with mechanical track brakes, controlled by a large braking lever next to the grip lever. Pulling back on this lever forces replaceable pine wood blocks against the rails; as a result, a cable car descending a steep hill emits an odor of smoldering wood. These track brakes are routinely used many times while traversing a cable car route.
The true emergency brake on a cable car is known as a "slot blade," a steel wedge that can be forced into the slot-rail between the running rails by a strong spring. If a runaway car is moving fast enough that the slot blade is necessary, the friction has been known to weld the blade to the slot rail, disabling the transit line until the obstruction can be extracted with a cutting torch. The slot blade is controlled by the large red lever near the grip, and is not used except for emergency stops.

On with the dance! let joy be unconfined;
No sleep till morn, when Youth and Pleasure meet
To chase the glowing Hours with flying feet.”
