Idea of Railcar Icon
There is a rectangular shape, and the top corners are rounded. There are four small squares with rounded corners evenly distributed near the top of the rectangle. On the bottom of the rectangle, there are four circles, two sets of two circles joined together by a line. Each set is on opposite ends of the rectangle.
This is a Railcar icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
