MRT-3 Light Rail Icons

This is the third icon in my local transportation series. I worked on the filled version more than 2 years ago but I didn't get to make a final decision about it until today. I also made an outline version just now.

The design is based on the MRTC 3000 class light rail vehicle built by Czech company ČKD Tatra for the Metro Rail Transit in Manila. It follows the Material Design system icon grid, drawn on a 24 × 24 px canvas.

Above are some drafts. I ended up choosing the version with headlights because they read more as trains in small sizes.

These should be available via the Noun Project soon. Unfortunately, their review processing time is currently 18 weeks. :(
