It's an icon for a subway train. It's the front of the subway train where the destination sign is on the top. The middle part of the train has two windows for the conductor to see out of. Below these windows are the headlights for the subway. The subway is aligned on two tracks that are jutting out in front of it.
This Subway icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
