then i suggest to build a new type of pre-signal that won't left the slow trains to proceed, and build a junction to a second binary for slow trains:
Code: Select all
-----> fast trains
x o
-----\----|---------------------/-----|--
----\-\------------------------/-/-------
\ \ o o / /
\ \-|----------------|-/ /
\ \----------------------/
\------> slow trains
o
|
no-slow train pass signal
x
|
the slow trains go to the second track and wait that the fast train pass, then the slow train return to the main track
