Dear Garry,
Thank you for your emails. Great to hear that more and more countries are benefiting from
the ORM project.
I agree with the plan for a ‘4th_rail’ tag and agree with Maarten that we should change
the ‘rail’ tag to ‘3rd_rail’. If I remember correctly, in the past it was already possible
to view the electrification map beta on a website from Michael (CC). Moreover, you can
download the JOSM editor and try out the electrification style there; this allows you to
easily add data while seeing the result at the same time. If you need any help with
setting that up, feel free to send me an email.
Best regards,
Jeroen Wegdam
