The icon is comprised of a short section of train tracks with a semaphore directing oncoming trains to stop pointing out from the right. There are three planks over which rails are laid and the semaphore is circle-shaped. The icon represents a train being commanded to a stop.
This is a Stop Train 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 13,300 icons, all in the same style and quality.
