EITs/AI  SAR Peterborough Scenarios EIT, AI and Manual Driving Tutorial 
A part of the SAR Peterborough Base Session
      Next Down Bottom

Enhanced Interlocking Towers (EITs) are included in the SAR Peterborough Base Session (they are not part of the route or layout) to provide easier navigation in some of the more complex yards in the layout. The EITs provide paths into and out of the yards. In some cases they also provide direct paths through the yards.

DotPoint.JPG EITs are optional, they do not have to be used


EITs are setup at the following locations:-

  • Gladstone Down - to provide paths out of Gladstone in the directions of Jamestown and the Wilmington Line.
  • Gladstone Up - to provide paths into Gladstone from the directions of Jamestown and the Wilmington Line.
  • Caltowie - to provide paths into, out of and through Caltowie from the directions of Gladstone and Peterborough.
  • Jamestown - to provide paths into, out of and through Jamestown from the directions of Gladstone and Peterborough.
  • Peterborough West - to provide paths into and out of Peterborough from the directions of Gladstone and Quorn.
  • Peterborough East - to provide paths into and out of Peterborough from the directions of Terowie and Paratoo.
  • Paratoo - to provide paths into and out of Paratoo from the direction of Peterborough.
  • Terowie - to provide paths into and out of Terowie from the direction of Peterborough.
  • Orroroo - to provide paths into, out of and through Orroroo from the directions of Peterborough and Quorn.
  • Carrieton - to provide paths into, out of and through Carrieton from the directions of Peterborough and Quorn.
  • Quorn - to provide paths into and out of Quorn from the direction of Peterborough.

Gladstone and Peterborough have each been split into two EITs because of the large number of paths at each location.

Driver Commands are available for use in the session.
DotPoint.JPG Driver Commands are optional, they do not have to be used


Apart from the standard commands (Drive To, Load, Unload, Couple, Wait For, etc), additional commands have been added. Specifically:-

  • IT SetPath (TANE SP4 and later) - to allow EIT paths to be set in the Driver Command Bar
  • IT CancelEnhancedPath (TANE SP4 and later) - to cancel any set EIT path
  • Instant Load Command - to instantly load all wagons (except locos) with the first item in their product queues
  • InstantLoadLocos - to instantly load all locos (or their tenders) with water and either coal or bunker c oil
  • InstantUnload - to instantly unload all wagons (except locos)

 The Tutorial Scenario 

The scenario used in this tutorial is 1 Gladstone-Peterborough Depot Fuel which has the consist already fully assembled with its locomotive (T 258) at the starting signal of the Gladstone EIT  Goods Loop to Broken Hill  path. This tutorial will follow the scenario until the consist arrives at Jamestown.

Getting Started:

After starting the Gladstone-Peterborough Depot Fuel session, find the loco and its consist. Either:-

  1. Open the Finder Tool (press CTRL-F) and type, in the name field, the name of the loco, SAR T 258 (or just T 258 should be enough). Click the tick icon, OR
  2. Open the Driver List (bottom left of the screen) and select the loco from there - click the drivers Eye icon to jump to the loco.


 The Driver Command Bar 
Make sure that the Driver Command Bar is visible on the screen. In Driver Mode the interactive driver controls are at the bottom right of the screen.

 Using the Gladstone EIT 

The first path to be set in this tutorial is from the Gladstone  Goods Loop  to  Broken Hill . On the Gladstone Tab PH Grey.png page (link via Location Index - link will open in this window) this is identified on that page as:-

M to P Path

From the open Driver Command Menu, select the  IT SetPath (TANE SP4 and later)  option. This will open a list of all the EITs that have been placed in the Session. Because an EIT Starting Signal, in this case invisible signal GSX G27D, is directly in front of the loco, the signal will be included in the EIT list.

Starting Paths

Select the starting signal  GSX G27D . This will reveal that two different paths out of Gladstone start from this signal.

  •  Goods Loop to Broken Hill , and
  •  Goods Loop to Wilmington 


Select the path  Goods Loop to Broken Hill .

DotPoint.JPG Selecting a path to or from an outside location will NOT set the entire path to/from that location (e.g. all the way to Broken Hill). It will only set the path between the Starting Signal and the Exit Signal. Either both signals will be just outside the yard or one will be within the yard and the other just outside


Every path is named according to its starting point (one of five outside locations or a track in the local yard) and its destination (one of five outside locations or a track in the local yard). The five outside locations are Port Pirie, Broken Hill, Terowie, Quorn and Wilmington. Those locations may not be the destination or starting point of the consist but they indicate the direction of travel only.

Path on map The path has now been set.

All junction switches and signals along the selected path from the Start Signal (GSX G27D) to the Exit Signal (Gladstone Home Up) are set to give loco T 258 the road out of Gladstone towards Broken Hill.

Note: not all signals will automatically show Proceed once the path has been set. Some signals, semaphore signals for example, will only show Proceed when a train starts moving towards the signal.


 Cancelling a Set EIT Path 

Paths that have been set can be cancelled so that their signals and junction switches will be returned to their previous states.

Set paths are automatically returned to their initial states after the consist has cleared the Exit Signal, but if you change your mind and decide to take a different path or not use the EITs then a set path can be cancelled.

From the Driver Command Menu select the IT CancelEnhancedPath command.

Cancel Path

You will have the option of cancelling ALL PATHS or selecting a particular EIT and path to cancel.

 Driving From Gladstone to Caltowie 

DotPoint.JPG There is a minor location, Yangya, between Gladstone and Caltowie but it has no EIT, minimal yard infrastructure, no signals and its switches are set for the main line through to Caltowie


You have two options for driving to Caltowie, the next EIT location. Manual and AI control.

DotPoint1.JPG  Manual Control 

You can manually drive the train through to Caltowie without using the EIT (as described in Step  1  above). This requires that all the switches along the path are correctly set first. You can do this by manually using the information on the Gladstone Tab SW Grey.png page (link via Location Index - link will open in this window).

Gladstone Switches

Switch Set
Part of this page is shown left with only those switches relevant to this tutorial scenario. The red dots indicate the yard Start and Exit positions for the train path.

Also shown left below is the Switch Set data, taken from the same page, for the path Gladstone  Goods Loop  to  Broken Hill . The switch directions, L or R are the directions when facing the junction fork i.e. the L and R that determine which direction a train will take when passing over the junction.

Switch  20  does not need to be set as the consist is beyond the switch.


You can now use the Driver Speed Dial or the keyboard controls to drive the train out of Gladstone Yard to Caltowie. Alternatively, for those with advanced steam loco driving skills, you can take control of the throttle, brake and other various devices in the loco cab.

DotPoint2.JPG  AI Control 

You can also drive by adding Driver Commands directly into the Driver Command Bar on the bottom right of the screen. The Drive To, Drive to Trackmark, Drive via commands that will automatically set all the switches are available in all scenarios for your use. A large number of track marks and some industies have been added to provide destinations for these commands.

The approach to every location in the route has TM Track Marks added to allow you to let the AI do most of the driving work.

DotPoint.JPG All locations in the route have Approach Track Marks placed a short distance ahead of the approach or Home signals, both visible and invisible, that protect the yard entry point
DotPoint.JPG Locations that do not have visible Home signals (and many of the locations do not) then a visible Caution track sign has been placed alongside the track at the position of the Approach Track Mark as a stopping guide if you are driving manually


The Track Marks are shown on the Caltowie Tab TM Grey.png page (link via Location Index - link will open in this window).

Caltowie Approach

Part of this page is shown left. The approach track mark on the Port Pirie side is Caltowie Main Approach Dn. This is also identified in the data table, also copied from the same page, shown below.

Caltowie TM

From the Driver Command Menu select the command  Drive To Trackmark  then find and select the track mark  Caltowie Main Approach Dn .

PencilTips.PNG Using the Drive commands in yards with many switches, such as Gladstone, will work but the consist will display a "stop-start" motion as it slowly navigates its way through the switches. If you use the EIT to set the path first then use the Drive commands, the consist will move without any delays.

 Using the Caltowie EIT 

  You can set an EIT path without having to be directly in front of a Starting Signal. For example, you can set all the EIT paths for the train through Caltowie and into Jamestown before you even leave Gladstone.
PencilTips.PNG To set a path for a distant EIT, open the Driver Command Menu and select the  IT SetPath (TANE SP4 and later)  option. Then select the required EIT and path from the lists. This can be repeated for as many EITs as needed along the path of the train.


Caltowie EIT

Open the Driver Command Menu and select the  IT SetPath (TANE SP4 and later)  option. Then select the  Caltowie EIT Interlocking Tower . This will open a list of ALL the EIT paths controlled by the Caltowie EIT, including any paths that will not be directly accessable to your consist.

On the Caltowie Tab PH Grey.png page (link via Location Index - link will open in this window) the path we will select is identified as:-

A to B Path

Select the path  Port Pirie to Broken Hill . This will set a direct path, via the  Main  Line, through Caltowie Yard and out towards Broken Hill.

Caltowie AB

You could also select any of the  Port Pirie to ...  paths. The only other through path is  Port Pirie to Station to Broken Hill  which will take you through the yard via the Station. The other  Port Pirie to ...  paths will take you into the yard but will not provide a set path out. You will need to select and set the appropriate  ... to Broken Hill  paths to exit the yard.


  If you have manually driven to the Caltowie Home Dn signal (or used the AI Drive To Trackmark Caltowie Main Approach Dn command) then open the Driver Command Menu. The name of the Start Signal  Caltowie Home Dn  will appear in the EIT list.
Caltowie Home EIT

Select  Caltowie Home Dn . This will open a list of all its assigned paths.

Select the through path you want, for example  Port Pirie to Broken Hill  or  Port Pirie to Station to Broken Hill .

 Driving Through Caltowie to Jamestown 

DotPoint1.JPG  Manual Control 

Caltowie does not have a coal stage or a fuel oil store in need of a refill so the consist will not be stopping here.

To manually drive the train through Caltowie to Jamestown without using the EIT you will have to manually set all the switches yourself using the information on the Caltowie Tab SW Grey.png page (link via Location Index - link will open in this window).

Caltowie Switches Because Caltowie is a fairly simple yard, the switch sets are not complex.
  •  Port Pirie to Broken Hill  via  Main  -  1 -R  2 -L  6 -R  7 -L
  •  Port Pirie to Broken Hill  via Station -  1 -L  7 -R

Notice that the Switch Track Diagram shows three switches in red with letters as IDs -  A    B    C .

These special switches are identified on the Caltowie Tab SW Grey.png page as Catch Points which are also known as Derails. They are designed to derail runaway wagons and prevent them from fouling the running lines. Most yards in the route have at least one Catch Point.

Catchpoints

The information above shows that the default position of the Catch Points, the first direction setting shown as an (L) or an (R), is set to  Catchpoint  which is the Derail position.

DotPoint.JPG If you are manually driving through a yard, then you MUST correctly set each  Catchpoint  on your path yourself otherwise your train will DERAIL


If you are using EITs or the AI Drive commands to navigate through a yard, then any  Catchpoints  along the path of your train will be automatically set to allow the train to safely pass.

DotPoint2.JPG  AI Control 

After reaching Caltowie you can use the Track Marks placed in the yard to navigate your way through. The track marks are shown on the Caltowie Tab TM Grey.png page (link via Location Index - link will open in this window) with a section containing a few that are relevant to this tutorial reproduced below with a secion of the Track Mark details from the same page.

Caltowie Map Track Marks Caltowie Exit TMs

All stations on the route have track marks, including the passenger enabled stations. This allows you to use the Drive To Trackmark command to reach any passenger station. The track marks are named using the name of the station (e.g. Caltowie), the word Station and the direction of travel, Up or Dn. So Caltowie has the station track marks Caltowie Station Dn and Caltowie Station Up (not shown above).

DotPoint.JPG Most stations on the route are NOT passenger enabled which reflects the level of passenger traffic that existed at those locations. The Drive To Trackmark command has to be used to bring a train alongside these stations when using the AI
DotPoint.JPG The Tab IN Grey.png page at each location (Location Index) will show the status of each station

You have a number of options for using the AI to navigate through the yard to the other side:-

  •  Drive To Trackmark  Jamestown Main Approach Dn which will ignore the Caltowie track marks and the AI will select its own logical route through the yard on its way to Jamestown
  •  Drive To Trackmark  Caltowie Station Loop Dn will force the train to travel via the Station to the end of the Station  Loop . This should be followed by a  Drive To Trackmark  Jamestown Main Approach Dn to reach Jamestown
  •  Drive To Trackmark  Caltowie Main Dn will force the train to travel to the end of the  Main  Line. This should be followed by a  Drive To Trackmark  Jamestown Main Approach Dn to reach Jamestown
  • The two options above could also use  Drive Via Trackmark  for their first command.

 Using the Jamestown EIT 

Jamestown is the final destination of this tutorial but the Gladstone-Peterborough Depot Fuel Scenario continues on to Peterborough.

In this tutorial scenario, we will be using the path into the  Loop  road. The Jamestown Tab PH Grey.png page (link via Location Index - link will open in this window) shows all the EIT paths into and out of Jamestown.

The Jamestown Tab PH Grey.png page identifies the path as Jamestown AtoD

  1. Open the Driver Command Menu and select the  IT SetPath (TANE SP4 and later)  option.
    • If you prefer to set the path into Jamestown well before arriving, then the name  Jamestown EIT Interlocking Tower  will appear in the EIT list. Select this EIT.
    • If you have manually driven to the Jamestown Home Dn signal (or used the AI Drive To Trackmark Jamestown Main Approach Dn command) then the name of the Start Signal  Jamestown Home Dn  will appear in the EIT list. Select this Start Signal.
  2. In either case, the path name  Port Pirie to Loop  will appear in the list of available or assigned paths. Select this path.
Jamestown Loop Path The path has now been set

All that remains now is to use the Driver Speed Dial, the keyboard or on screen controls to drive the train into Jamestown  Loop  and halt at the end of the loop.

This ends the tutorial but you can continue the Gladstone-Peterborough Depot Fuel Scenario.
