It's a logo of a cable car travelling along the cable. The car has two windows on it with a line connecting up to the cable and two wheels on top of the top cable. The main cable is slightly diagonal from left going up to the right.
This Cable Car icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,000 icons, all in the same style and quality.
