In real-world railways, a so-called interlocking system is a set of railway
|
||
|
|
signals and trackside equipment.
|
||
|
|
Its purpose is to prevent conflicting train movements which otherwise could
|
||
|
|
result in derailing or colliding trains.

\begin_layout Standard
|
||
|
|
Real-world interlocking systems perform this task by setting routes.
|
||
|
|
A route is a path along a track that a train can safely pass.
|
||
|
|
To set a route for a train, the signalman (the operator of a signal box)
|
||
|
|
has to set switches (turnouts) to the correct position and lock them in
|
||
|
|
order to make a signal for a train show

|
||
|
|
|
||
|
|
.
|
||
|
|
In newer systems, this is done automatically by the interlocking system.
|
||
|
|
A route can not be set if switches are locked to a wrong position by another
|
||
|
|
route or if any portion of the route is occupied by a train.

The interlocking system in this Minetest mod tries to follow real-world
|
||
|
|
interlocking systems as far as applicable.
|
||
|
|
It divides tracks into track sections and implements a route setting mechanism
|
||
|
|
following the same principle.
|
||
|
|
\end_layout
|
||
|
|
|

|
\begin_layout Standard
|
||
|
|
However, for the sake of simplicity of implementation and usage, not all
|
||
|
|
concepts of real-world interlocking have been taken over.
|
||
|
|
Especially, there is no mechanism for overlap.

In the real world, a line of track is divided into so-called track sections,
|
||
|
|
or track circuits.
|
||
|
|
Those systems often can not tell where exactly a train is, but only which
|
||
|
|
track sections it occupies.
|
||
|
|
A route can never be set through an occupied track section.

\begin_layout Standard

|
In this mod, you will not directly configure the locations of track sections.
|
||
|
|
Instead, you designate the borders of each track section using a special
|
||
|
|
node, the Track Circuit Break, abbreviated TCB.
|
||
|
|
\end_layout
|
||
|
|
|
||
|
|
\begin_layout Standard
|
||
|
|
For example, if you want to create a track section for a piece of a main
|
||
|
|
running line, you set up two TCBs at the ends of this track circuit.
|
||
|
|
\end_layout
|
||
|
|
|

\begin_layout Standard

Setting up a TCB works as follows:

|
|
\end_layout
|
||
|
|
|
||
|
|
\begin_layout Enumerate
|
||
|
|
Place a TCB node somewhere near the place where the circuit break is going

|
|
to be located.

\end_layout
|

|
|
|

\begin_layout Enumerate

Now you have assigned the TCB node to a rail.
|

This will bring up a form which looks as follows:

You see that the form is divided in side A and side B.
|
||
|
|
To designate where each side is, a marker is displayed on the rail.
|
||
|
|
You can always make this marker show up by punching the TCB node, and remove
|
||
|
|
it by punching the marker.

Both sides are shown as

The same procedure is applicable when you create a turnout track section,
|

|
|
except that you have to set up three or more TCBs.

\end_layout

The AdvTrains interlocking system allows you to add more TCBs after you
|
||
|
|
have created a track section.
|
||
|
|
This works without problems in most cases.
|
||
|
|
For example, you can easily insert a turnout into an already set-up track
|
||
|
|
section and create another TCB behind it, and AdvTrains will automatically
|
||
|
|
detect the existing track section.
|
||
|
|
Problems arise only if you try to insert a TCB in-between a section, in
|
||
|
|
which case both sides of the TCB will end up assigned to the same section.
|
||
|
|
The code currently does not handle this case properly, so try to avoid
|
||
|
|
this situation by all means.
|
||
|
|
As a last resort, you can always dissolve a faulty track section, as described
|
||
|
|
in the next chapter.

If you try to set up a track section that is longer than 1000 nodes, advtrains
|
||
|
|
won't recognize the TCB at the other end because of a safety limit in the
|
||
|
|
traverser function, which is supposed to prevent deadlocks.
|
||
|
|
This case has happened when the Track Section overview screen only shows
|
||
|
|
one TCB in the list.
|
||
|
|
The procedure for this is as follows:

Since rail crosses are created by laying tracks across each other without

Of course, you can always control any variable signal by traditional means

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,

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
|

A so-called route is a locked path between two main signals, which locks
|
||
|
|
all turnouts in the correct position.
|
||
|
|
Its purpose is to offer a train a path on which it can safely proceed without
|
||
|
|
interfering with any other train.
|
||
|
|
A route always incorporates and locks one to multiple track sections, starting
|
||
|
|
with the one that lies directly behind the

Example: Imagine a station with 2 platforms on a single track running line.

We are looking at signal A.

You probably want trains coming from the right to go into platform 1 or
|
||
|
|
into platform 2, so you need to program 2 routes.

always start at a signal (A) and end at a signal facing in the

For this to work, you need to specify all track sections the train will

pass along, as well as the positions of all turnouts that need to be locked.
|
||
|
|
Those are not only the turnouts that lay directly on the train's route,
|
||
|
|
but also some turnouts on adjacent tracks, the so-called flank protection.

The upper turnout, of course, needs to be locked in straight (normal) position,
|
||
|
|
while the lower one is not relevant for the route itself.
|
||
|
|
But what if the lower turnout was set to the diverging (reverse) position
|
||
|
|
and the driver of another train approaching signal B fails to see the red
|
||
|
|
light? This train would crash into the first one.
|
||

To minimise danger, that other train would need to be routed towards signal

There are, of course, situations, where both positions of a turnout would

conflict with a route equally.
|

In those situations, there's nothing you can do and no flank lock needs

to be set.

In early real-life interlocking systems, routes either had to be cancelled

|
by the signalman after the train had passed the route, or there was a single
|

|
|
release contact at the end of the route.
|
||
|
|
However, as interlocking systems evolved and the position of trains is
|
||

now roughly known by the track sections, portions of the route can be freed
|

as soon as the train has left the corresponding section.

AdvTrains has chosen a modern approach to route releasing.
|
||
|
|
Each turnout lock is associated to a track section belonging to the route's

path.
|

|
|
Once the train leaves this section, all assigned locks are also freed.

Please note that reversing a train outside of stations is not only discouraged,

but also very dangerous, because even real-world interlocking system do

|
not expect this.
|
||
|
|
There is a clear, human-sense rule that you should never reverse the driving
|
||

|
direction of a train while on a main line or on a turnout.
|

|
Else, you can be considered a terrorist.

It is possible to overrun red signals, if a route is cancelled while a train

is approaching.
|

Real interlocking systems use a mechanism called Approach locking for this,
|

|
|
however, as of now, there's no similar system in this mod.
|

If a red signal is overrun, the train brakes using emergency brake (

It may be possible that the route can not be set, because one or more other

routes conflict with the current one, or a section is blocked.

In this case, the signal stays red, and the conflicting item is shown in

the formspec.
|

As soon as the conflict is resolved (by cancellation or release of the

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
|
||
|
|
med 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.

A single ARS rule can either match a line or a routing code (combinations,

and's, are not yet supported).

after the train passed, ARS sets the route only when the train approaches
