maximum permitted speed of the line. This is the regular operation mode for trains. Shunt signals have no meaning for
train moves.

may never leave a station except into a siding. Also, shunt moves may drive at a maximum speed of 6 speed units, because

vehicles, even shunt routes)</li></ul>

interlocking systems can automatically set routes based on a pre-programmed routing table for each particular train. Since one
outstanding feature of Advtrains is it&#8217;s high degree of automation, it has a similar system to automatically set routes for a train
depending on certain parameters.

\subsection{Main and Shunt signals}
\subsection{Signal Aspects}
While static signals are mainly used for speed restrictions, the interesting
ones are variable signals. Of course, you can always control any variable
signal by traditional means (mesecons, digiline, right-click) if the
signal allows it, but that misses the point of this interlocking system.
A signal aspect is a piece of information that a signal shows to the
train driver. It contains information about whether and at what speed
the driver may proceed at the signal.
Every signal, both static and dynamic ones, imposes a certain aspect
to trains passing the signal. For static signals, this is always the
same aspect, such as ``Proceed at speed of 8'' or ``Shunt moves
may not pass''. Dynamic signals, however, can display multiple different
aspects. The default for them is always as restrictive as possible,
mostly ``Halt!''.
You should know that both static and dynamic signals use exactly the
same properties for signal aspects. There is no difference in the
meaning of the aspect definitions.
In the following sections, we will talk about main signals. By this,
we mean a variable signal that can display both a ``Danger'' aspect
(trains are not allowed to proceed) and at least one ``Proceed''

restriction), which act as an ``entry signal'' for one or multiple
routes.
\subsection{Train moves and Shunt Moves}
\begin{itemize}
\item A ``Train move'' is a train that is running, going to run on or
coming from a main line between stations, passing through or stopping
at a station. Train moves can expect that there are no obstacles on
the route and they can proceed at the maximum permitted speed of the
line. This is the regular operation mode for trains. Shunt signals
have no meaning for train moves.
\item A ``Shunt move'' is a train that moves within a station and/or is
coupling or decoupling wagons or engines. A shunt move may never leave
a station except into a siding. Also, shunt moves may drive at a maximum
speed of 6 speed units, because it is usually not ensured that the
path is free of obstacles. (however, advtrains ensures that every
route is free of railway vehicles, even shunt routes)
\end{itemize}
There are also 2 general types of signals: Main signals and Shunt
signals. While main signals have a meaning for all types of trains,
Shunt signals only have to be followed by shunt moves. Usually, Shunt
signals that are on a train move route are set to a Proceed aspect
as well.
When a train reverses, its mode automatically changes to ``shunt
move'' until it passes a main signal that shows ``Proceed as train
move'', which is usually designated by a green light. From this point
on, it can accelerate to maximum permitted speed.
Some main signals, like the ones from the Ks signals mod included
by default, can also display ``Proceed as shunt move'', which is
designated by 2 white lights along with the red light. Once a train
passes this signal, it becomes a shunt move.

clearly not.

to set individual aspects for routes, this is a feature still to be
implemented soon.}

This is the screen that appears when you click ``Edit Route''. It
lets you change the route name and delete the route. Also, it shows
a summary of the route and its elements.
The route summary lists information per track section on the route,
so the line starting with ``1'' is the first section of the route.
The ARS rule list and its purpose is explained later.
\subsection{Specifying signal aspects}
By default, newly programmed routes show an aspect that comes closest
to ``Proceed at maximum speed''. However, it can be desirable to
change this behavior, like when the route passes a diverging turnout,
the train should be signalled to drive slower, or the route is a shunt
route and therefore only ``Shunting allowed'' should be shown.
This is the purpose of the ``Change Aspect'' button in the route
info screen.
Signal aspects in advtrains consist of 4 sections: main (Information
for train moves), dst (Distant signal information, not implemented
yet), shunt (Information for shunt moves) and info (additional information,
currently not in use).

8''
\item Train may proceed as shunt move: ``shunt: free''
\end{itemize}
There's a field in the ``shunt'' part of signal aspects that is
not displayed in the GUI, but is of potential interest to developers
of signal addons: shunt.proceed\_as\_main.
\begin{itemize}
\item A train move can always become a shunt move by passing a signal that
shows ``Halt for train moves, shunting permitted''
\item A shunt move can only pass a signal saying ``Proceed as train move,
shunting not permitted'' when proceed\_as\_main is true.
\end{itemize}
The property is used by the Limit Of Shunt sign, where proceed\_as\_main
is set to false. Shunt moves have to stop in front of it, while train
moves are signalled ``Proceed''. Regular main signals that show
``green'' have the field set to true, so that all trains can pass
it.

access to a siding. You'd enable automatic working for the main route
and cancel it only when you need a train to go into the siding.
\subsection{Automatic Route Setting (ARS)}
As interlocking systems evolved, the goal always was to offload work
from the human to the system, automating things. Modern interlocking
systems can automatically set routes based on a pre-programmed routing
table for each particular train. Since one outstanding feature of
Advtrains is it's high degree of automation, it has a similar system
to automatically set routes for a train depending on certain parameters.
Every train in Advtrains has 2 internal properties that can be set
through the Onboard Computer of every engine in the train, the ``Line''
and the ``Routing Code''
\begin{itemize}
\item The ``Line'' property is supposed to distinguish trains of multiple
lines that share a track.
\item The ``Routing Code'' property is supposed to tell the target of
a train or which route it should take to reach the target
\end{itemize}
Examples:
\includegraphics{11_home_moritz_Home_Projekte_Minetest_minetest_mods_advtrains_assets_lyx_img_arslin_ex1.png}
Both lines share the section between Blackbirdshire and Parktown.
To divert them again, they can save their line number in the ``Line''
field.
\includegraphics{12_home_moritz_Home_Projekte_Minetest_minetest_mods_advtrains_assets_lyx_img_arslin_ex2.png}
Some trains should go to B, some to C, the direction can be set with
a routing code.
One single routing code should not contain spaces. You can set multiple
routing codes by just separating them with spaces in the Routing Code
field. So, ``Stn Ori'' would be matched by ARS rules either containing
``Stn'' or ``Ori''. This does not work for lines.
\subsubsection{Writing ARS Rules}
Every route of every signal can be given a set of ARS rules. A single
ARS rule can either match a line or a routing code (combinations,
e.g. and's, are not yet supported). The first rule in the first route
that matches any of the properties of the train is selected, and that
route is set for the train.
\includegraphics{13_home_moritz_Home_Projekte_Minetest_minetest_mods_advtrains_assets_lyx_img_ars_ex1.png}
You can add an asterisk (``{*}'') to the ARS rules of one route.
That route then becomes the default route.
If no explicit ARS rule matches the train, then the default route
is chosen and set. If there is no default route, nothing happens and
the signal remains red.
\subsubsection{Using ARS}
In contrast to Automatic working, where the route is re-set immediately
after the train passed, ARS sets the route only when the train approaches
the signal, e.g. is just about to start braking in front of it.
At any place where one of the following things take place, you should
use the ARS system in favor of Automatic Working:
\begin{itemize}
\item A main line diverts into 2 or more lines: Using ARS, you can direct
the trains along the line where they should go
\item Two or more main lines join into one: You cannot use automatic working
here, because all routes are tried to be set at the same time and
it is a matter of luck which one ``wins''. In a bad situation, you
have a train coming from A, but it cannot proceed because Signal B
has won the ``route race'' into the shared section, even if there's
no train coming from B. Using ARS, by just specifying the ``default
route'' by a {*}, the inward route is only set when a train approaches.
\item Complex intersections, which are probably a combination of the above
two
\item sometimes-used branching tracks on which only certain trains (with
certain routing code or line) should head off, like the entrance to
a factory where only one specific goods train should drive in.
\end{itemize}
In the route overview, you can see some information on the ARS settings:
All routes that have ARS rules are highlighted red, the ``default
route'' is highlighted green.
ARS does not affect signals which already have a route set, and signals
which are operating under ``Automatic Working''.
\section{Final notes}
The interlocking system is mainly finished, though there are still
some plans and ideas. They include:
\begin{itemize}
\item Signalbox panels, as revival of itrainmap
\item Individual signal aspects for routes
\item Distant signals
\item On-Train head-up display for oncoming signals (they have something
like this in Czech Republic, I forgot how it's called.)

Automatic Route Setting (ARS)
\end_layout
\begin_layout Standard
As interlocking systems evolved, the goal always was to offload work from
the human to the system, automating things.
Modern interlocking systems can automatically set routes based on a pre-program

Since one outstanding feature of Advtrains is it's high degree of automation,
it has a similar system to automatically set routes for a train depending
on certain parameters.

Writing ARS Rules
\end_layout
\begin_layout Standard
Every route of every signal can be given a set of ARS rules.
A single ARS rule can either match a line or a routing code (combinations,
e.g.
and's, are not yet supported).
The first rule in the first route that matches any of the properties of
the train is selected, and that route is set for the train.
\end_layout
\begin_layout Standard

\end_layout
\begin_layout Standard
You can add an asterisk (
\begin_inset Quotes eld

\begin_inset Quotes erd
\end_inset
) to the ARS rules of one route.
That route then becomes the default route.
\end_layout
\begin_layout Standard
If no explicit ARS rule matches the train, then the default route is chosen
and set.
If there is no default route, nothing happens and the signal remains red.
\end_layout
\begin_layout Subsubsection
Using ARS
\end_layout
\begin_layout Standard
In contrast to Automatic working, where the route is re-set immediately
after the train passed, ARS sets the route only when the train approaches
the signal, e.g.
is just about to start braking in front of it.
\end_layout
\begin_layout Standard
At any place where one of the following things take place, you should use
the ARS system in favor of Automatic Working:
\end_layout
\begin_layout Itemize
A main line diverts into 2 or more lines: Using ARS, you can direct the
trains along the line where they should go
\end_layout

A shunt move may never leave a station except into a siding.
Also, shunt moves may drive at a maximum speed of 6 speed units, because
it is usually not ensured that the path is free of obstacles.

even shunt routes)
