An attempt was made to get accurate track alignment files that we can use under the ODBL. Amaroussi initiated this project, with the first consultant being the AR.DE.CO, who worked with nearly all Athens Metro projects.

Dear Sir/Madam,
Please could you publish an accurate shapefile export of the Athens Metro lines 2 and 3, containing the individual track centre-lines for the route between Anthoupoli and Elliniko (Line 2) and between Dimotiko Theatro and Doukissis Plakentias via Eleonas (Line 3) respectively?
Please export this directly from the GIS/CAD files, showing individual track centre-lines, and so that it is compatible under the Open Data Commons Open Database License (https://www.openstreetmap.org/copyright).
The track centre-line export should show both track centre-lines separately, including crossovers, turnback facilities and stabling/maintenance sidings.
It may be useful to include the following where they already exist in the dataset during export:
