Hi, let me share some news from Maps.Me PT preprocessor.
1) Fetching data from overpass API has been release. Now only Python interpreter is needed to validate transport networks for a city or a small country. The scenario with minimum options is: mkdir /tmp/subway # generate validation file in json format python3 process_subways.py --bbox -c "Hamburg S-Bahn" -l /tmp/subway/validation.json # generate HTML output python3 validation_to_html.py /tmp/subway/validation.json /tmp/subway/ 2) You can observe a validated PT network scheme on the map. Follow «View on the map» link at the preprocessor page: http://osm-subway.maps.me/index.html <http://osm-subway.maps.me/index.html> Only networks passed validation are shown. This rough visualization aims validation, no high representative quality currently implied. Bug reports and other feedback is welcome.
