Adding "Sweden" is somewhat confusing, since it is also used in Norway.
Perhaps ATC-2/Ebicab 700 would be a better option, and use the same
rendering for Sweden, Norway, Bulgaria and Portugal. At least now, the same
colour is used in Portugal, Sweden and Norway.
"ATC-2/Ebicab 700" really looks like a compromise solution. It's not
elegant, even though it does solve the issue. But it doesn't seem like there are
other, more elegant solutions here (unless simply Ebicab 700 is used, but that's
twisting facts a bit, apparently).
There is also still the question about the Norwegian systems FATC and DATC. While FATC is
still ATC-2/Ebicab 700, DATC is different in some way. I have not found out exactly what
the *technical* difference is, whether any ATC-2/Ebicab 700 equipped train would
understand DATC telegrams or not. Would it make sense to map it as a separate safety
system? (In my opinion yes, as it is differentiated in the rules).
Have you edited Swedish railway lines to include railway:atc=yes ? I would like more than
two opinions on this - especially if we want to reach an agreement on how to change the
tag. Otherwise they could just revert the changes.
