Vector illustration of a subway train. Sketchy lines train going into a tunnel seen from a perspective. Number 3 seen on the back and a graffiti reading “NYC” on the side of the vehicle. Free vector subway train for all metro, transportation, public transport, underground, city life and New York designs.
These are recent images I converted to vectors with this command:
for i in *.jpg; do convert "$i" "`basename "$i" .jpg`.png" && autotrace -despeckle-level 15 -color-count 6 -input-format PNG -output-file "`basename "$i" .jpg`".svg -output-format svg "`basename "$i" .jpg`.png"; done
