Dear community,
As far as I can see, there are no objections to my proposal. If that remains the case
until Wednesday 10th of February, I’ll update the tagging scheme and start executing the
ToDo’s from option 1.
Best regards,

This tagging discussion is relevant for PR703 so I added a copy of this email there.
Dear community,
EBICAB is a trademark for on-board equipment, from a specific supplier (Bombardier). The
entire train protection system contains some other things [1]. The entire system is called
ATC in Norway and Sweden, while Portugal calls the exact same system CONVEL. To add more
confusion: Denmark calls [its own
system](https://de.wikipedia.org/w/index.php?title=ZUB_123) ATC [2], while it is
incompatible with the Norse/Swedish/Portuguese system.
Also the current situation in OSM is different than you currently envision (with adding
the `railway:ebicab=700` tag): in the past I already added `railway:atc=yes` tags to
relevant tracks in both Portugal and Norway with the same purpose. You also envision the
`railway:ebicab=900` tag (probably for Finland) while Finland uses the `railway:jkv=yes`
tag with the same purpose. Denmark is a bit of a blank slate, because Denmark doesn't
have train protection tags yet.
OpenRailwayMap has 2 options:
1. Render compatible systems
consequences:
a) we proceed with this PR as is
b) we have to retag Portugal, Sweden, Norway and Finland (I'm willing to help)
c) we should create an additional PR to also render `railway:zub=123`
d) Denmark should be tagged with `railway:zub=123`
2. Render local names
consequences:
a) this PR should change to `railway:convel=yes`
b) we should retag portugal from `railway:ebicab=700`/`railway:atc=yes` to
`railway:convel=yes`
c) we need an additional PR to render `railway:atc=yes`
c) Denmark should be tagged with `railway:atc=yes`
I am in favor of option 1, because my opinion is that the goal of ORM signalling layer
should be to show compatibility.
Best regards,
