\section{Introduction}\label{sec:intro}

  \subsection[About]{About tikz-trackschematic}

    The Ti\emph{k}Z-\emph{trackschematic} library is a toolbox of symbols geared primarily towards creating track schematic for either research or educational purposes.
    It provides a Ti\emph{k}Z frontend to some of the symbols which maybe needed to describe situations and layouts in railway operation.
    The library is divided into four sublibraries:
    \begin{itemize*}[label={}]
      \item \texttt{topology},
      \item \texttt{trafficcontrol},
      \item \texttt{vehicles},
      \item \texttt{constructions}, and
      \item \texttt{messures}.
    \end{itemize*}

  \subsection{Acknowledgement}

    This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 826347.

  \subsection{Requirements}\label{sec:require}

    The library uses Ti\emph{k}Z and it is based the following packages:
    \begin{itemize*}[label={}]
      \item \texttt{tikz},
      \item \texttt{lmodern},
      \item \texttt{xcolor}, and
      \item \texttt{etoolbox}.
    \end{itemize*}
    Further more it uses the following Ti\emph{k}Z libraries:
    \begin{itemize*}[label={}]
      \item \texttt{calc},
      \item \texttt{intersections},
      \item \texttt{patterns}, and
      \item \texttt{arrows.meta}.
    \end{itemize*}

\section{Usage}\label{sec:use}
  \subsection{A complete minimal example}

    The command \texttt{\textbackslash usetikzlibrary\{trackschematic\}} will load the library; place it somewhere in your preamble.
    Here is a complete working minimal example which will produce a single PDF file with the figure on the right:\\
    \begin{minipage}[c]{0.51\textwidth}
      \centering
      \begin{lstlisting}[gobble=8]
        \documentclass[tikz]{standalone}

        % loading the library
        \usetikzlibrary{trackschematic}

        \begin{document}
          \begin{tikzpicture}

            % draw a track
            \maintrack  (0,0) -- (6,0);

            % place a train on the track
            \train[forward] at (5,0) label ();

          \end{tikzpicture}
        \end{document}
      \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.45\textwidth}
      \centering
      \begin{tikzpicture}
        \path (-0.2,-1.45) rectangle (6.2,1.45);
        \coordinate (A) at (0,0);
        \coordinate (T) at (5,0);
        \coordinate (B) at (6,0);
        \maintrack  (A) -- (B);
        \train[forward] at (T) label ();
      \end{tikzpicture}
    \end{minipage}

  \subsection{Placement}\label{sec:placement}

    To place symbols in a track schematic, they need to placed and oriented correctly.
    The placement ist done through the given Ti\emph{k}Z coordinate.
    There are a few assumaptions made about the placement:
    \begin{enumerate}
      \item Parallel tracks are drawn at a distance of 1 cm (which is the base unit of Ti\emph{k}Z).
      \item Tracks are only drawn at an angle of $n \cdot 45^{\circ}$.
    \end{enumerate}

  \subsection{Orientation system}\label{sec:orientationsystem}

    The orientation is controlled via given Ti\emph{k}Z options or pgfkey.
    The orientation options/pgfkeys are named in relation to orientation-based coordinates, which inhibate thier meaning from reading left to right beeing \texttt{forward} and relate \texttt{left}/\texttt{right} to that movement.
    \begin{center}
      \begin{tikzpicture}[font=\ttfamily]
        \draw[<->] (-0.5,0) node[left] {backward} -- (0.5,0) node[right] {forward};
        \draw[<->] (0,-0.5) node[below] {right} -- (0,0.5) node[above] {left};
      \end{tikzpicture}
    \end{center}

    The main option/pgfkey is the \texttt{face} option to control in which direction an object will face.
    The key can take one of the following two values:
    \begin{itemize*}[label={}]
      \item \texttt{forward}, and
      \item \texttt{backward}.
    \end{itemize*}
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \train[face=forward ] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\train[face=forward] at (5,0) label ();}
    \end{minipage}
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \train[face=backward] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\train[face=backward] at (1,0) label ();}
    \end{minipage}
    As a shortcut you may also just give the option \texttt{forward} or \texttt{backward} without the \texttt{face=} in front of it.

    If you have objects which branch either to the left or the right you have to give the \texttt{branch} option which takes one of the following two values:
    \begin{itemize*}[label={}]
      \item \texttt{left}, and
      \item \texttt{right}.
    \end{itemize*}\\
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \turnout[forward ,branch=left ] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\maintrack (0,0)--(4,0);\maintrack (2,0)--++(0.5,0.5);\turnout[forward,branch=left] at (2,0) label ();}
    \end{minipage}
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \turnout[forward ,branch=right] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\maintrack (0,0)--(4,0);\maintrack (2,0)--++(0.5,-0.5);\turnout[forward,branch=right] at (2,0) label ();}
    \end{minipage}
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \turnout[backward,branch=left ] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\maintrack (0,0)--(4,0);\maintrack (2,0)--++(-0.5,0.5);\turnout[backward,branch=left] at (2,0) label ();}
    \end{minipage}
    \begin{minipage}[c]{0.68\textwidth}
    \begin{lstlisting}[gobble=6]

      \turnout[backward,branch=right] at (coordinate) label ();

    \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.30\textwidth}
      \tikz{\maintrack (0,0)--(4,0);\maintrack (2,0)--++(-0.5,-0.5);\turnout[backward,branch=right] at (2,0) label ();}
    \end{minipage}
    There is no shortcut and the key \texttt{branch=} must be given contrary to the key \texttt{face=}.

  \subsection{Left- and right-hand traffic}\label{sec:traffic}

    The traffic practice to divide bidirectional traffic has impact mostly on traffic control.
    The default traffic practice for this library ist right-hand traffic.
    You can change it either globally or locally with the key \texttt{traffic practice=left}.
    There is also the alias \texttt{position} for single local entries.
    \begin{minipage}[c]{0.65\textwidth}
      \begin{lstlisting}[gobble=8]
        \documentclass[tikz]{standalone}

        % load the library
        \usetikzlibrary{trackschematic}

        \begin{document}
          \begin{tikzpicture}
            % set the traffic practice
            \tikzset{traffic practice=left}

            \maintrack  (0,1) -- (5,1);
            \maintrack  (0,0) -- (5,0);
            \routesignal[forward]                at (2,1) label (left);
            \routesignal[forward,position=right] at (2,0) label (right);
          \end{tikzpicture}
        \end{document}
      \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.34\textwidth}
      \begin{tikzpicture}
        \tikzset{traffic practice=left}
        \path (-0.2,-1.6) rectangle (5.2,2.6);
        \coordinate (A1) at (0,1);
        \coordinate (S1) at (2,1);
        \coordinate (B1) at (5,1);
        \maintrack  (A1) -- ( B1);
        \coordinate (A2) at (0,0);
        \coordinate (S2) at (2,0);
        \coordinate (B2) at (5,0);
        \maintrack  (A2) -- ( B2);
        \routesignal[forward] at (S1) label (left);
        \routesignal[forward,position=right] at (S2) label (right);
      \end{tikzpicture}
    \end{minipage}

  \subsection{Colors: background and foreground}\label{sec:colors}

    The two main colors \texttt{white} and \texttt{black} are set for the \texttt{background} and \texttt{foreground} keys by default.
    If you want to change them, provide a new value for the keys.
    For example like this:\\
    \begin{minipage}[c]{0.65\textwidth}
      \begin{lstlisting}[gobble=8]
        \documentclass[tikz]{standalone}

        % load the library
        \usetikzlibrary{trackschematic}

        \begin{document}
          \begin{tikzpicture}
            % set the colors
            \tikzset{background=lightgray,foreground=violet}

            \maintrack  (0,0) -- (6,0);
            \train[forward] at (5,0) label (grey train);
          \end{tikzpicture}
        \end{document}
      \end{lstlisting}
    \end{minipage}
    \hfil
    \begin{minipage}[c]{0.34\textwidth}
      \begin{tikzpicture}
        \tikzset{background=lightgray,foreground=violet}
        \path (-0.2,-1.6) rectangle (5.2,1.6);
        \coordinate (A) at (0  ,0);
        \coordinate (T) at (4.5,0);
        \coordinate (B) at (5  ,0);
        \maintrack  (A) -- (B);
        \train[forward] at (T) label (grey train);
      \end{tikzpicture}
    \end{minipage}


\section{Provided Symbols and their commands}

  Each sublibrary provides different symbols. The following section will go through each symbol their command and options.
  % for aperance see the snippet document

  \subsection{Topology}
    
    \subsubsection{Tracks}\label{sec:track}

      Drawing a track follows the same pricipal as drawing a line in Ti\emph{k}Z.
      There are two generell optionss of track with different commands:
      \begin{itemize*}[label={}]
        \item \texttt{main tracks}, and
        \item \texttt{secondary tracks}.
      \end{itemize*}

      \symboldescription{Main track}
        \symbol{main_track.tikz}
        \begin{lstlisting}[gobble=10]
          \maintrack (coord1) -- (coord2);
          \maintrack (coord1) -- (coord2) -- (coord3) -- etc.;
        \end{lstlisting}
        No \texttt{options} available.\\
        This command is equivalent to:
        \begin{lstlisting}[gobble=10]
          \path[draw=foreground,line width=2pt] (coord1) -- (coord2);
        \end{lstlisting}
        Beware of the placement assumption by the library (see Section \ref{sec:placement}).


      \symboldescription{Secondary track}
        \symbol{secondary_track.tikz}
        \begin{lstlisting}[gobble=10]

          \secondarytrack (coord1) -- (coord2) -- (coord3) -- etc.;
        \end{lstlisting}
        For the secondary track you may also use the following alias:
        \begin{lstlisting}[gobble=10]
          \sidetrack (coord1) -- (coord2);
        \end{lstlisting}
        No \texttt{options} available.\\
        The command is equivalent to:
        \begin{lstlisting}[gobble=10]
          \path[draw=foreground,line width=0.7pt] (coord1) -- (coord2);
        \end{lstlisting}
        Beware of the placement assumption by the library (see Section \ref{sec:placement}).

          \tracklabel at (coord) label (number);
        \end{lstlisting}
        No \texttt{options} available.\\
        This command is equivalent to:
