The map is designed based on openmaptiles/openmaptiles. The maplibre stylesheet is currently closed and will be released later.

The map complies with Public Transport V2 (PTv2) protocol. Route roles of “alternate”, “forward” and “backward” from PTv1 are not recognized.

In short, this map:

1. visualizes OSM relations: route=train/subway/light_rail/tram/bus/trolleybus
2. shows stations from lower zoom
3. shows route ref and color

Next up we’ll describe each route type.

Train

Tint color: GRAY #898989

Train routes connect cities and towns via thick, dark gray lines that represent high passenger capacity and transportation significance. Stations are marked by circles with gray borders, accompanied by white text labels that feature gray halos for improved visibility.

Examples:

Subway and light_rail

Tint color: Subway GREEN #028940

Subway and light rail lines share the same visual styling. Their stations appear as circles smaller than train stations, with white text labels surrounded by green halos. Route reference numbers adopt colors specified in each route’s “colour” field, with computed halo colors that adjust to maintain proper contrast.

Examples:

Tram

Tint color: LIGHT BLUE #65BCE5

Tram routes follow similar styling principles but use thinner blue lines, with all text elements—station names, route references, and colors—scaled down proportionally from subway dimensions.

Examples:

Bus

Tint color: BROWN #A86F6F

Bus routes appear as the thinnest lines and overlay all other transit routes. Bus stops are marked by small rectangles, and unlike subway and tram routes, their reference numbers use the tint color regardless of the route’s “colour” field value.
