Correct. The meaning of these
signs is identical.
The new variant is the European standardized one (EN 16494).
I think it was a genius
idea to add the ":shape" subtag (*cough* *g*), and this could be easily used
here:
railway:signal:train_protection=DE-ESO:blockkennzeichen
railway:signal:train_protection:shape=circle
or
railway:signal:train_protection:shape=arrow
For the time being we must treat a missing :shape for the German signal as
"circle".
Afterwards we can start adding a rendering for this, which should be easy as
it's just a copy and color change of the "ETCS stop marker" image.
It
differs a little bit - the arrow has no border, but the board itself
has one:

Part 2:
Since this signal comes from the ETCS world it is likely in use outside of
Germany already, the German wiki page e.g. refers to Swiss "ETCS-
Standortsignal". The question is: how is the tagging of this type of signal in
other countries? Do they also use different shapes or does only the arrow form
exist there? Would be nice to know as that could be added to the rendering
rules at the same time.
I'm not sure whether there exist any standardized ETCS
location markers
outside Germany yet.
Location markers in another non standardized variant (white triangle on
blue board) exist on some high speed lines in Italy (e.g. Bologna -
Firenze).
