SAR Peterborough Narrow Gauge Scenarios Tutorial

A part of the SAR Peterborough Base Session

---

Enhanced Interlocking Towers (EITs or ITs) 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. They provide paths into and out of the yards. In some cases they also provide direct paths through the yards. ITs are optional, they do not have to be used ITs 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 ITs because of the large number of paths at each location.

The Tutorial Scenario  The scenario used in this tutorial is  Gladstone-Peterborough Depot Fuel which has the consist already fully assembled with its locomotive (T 258) on the  Goods Loop . This tutorial will follow the scenario until the consist arrives at Jamestown.

Getting Started: After starting the SAR Peterborough Base Session find the loco and its consist. Either:- 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 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.   Cycle Through the Command States Click the 3 dots on the extreme bottom right of the screen to cycle the control display through to the Driver Command Bar - stop when the last of the 3 dots is highlighted.     Open the Driver Command Menu Click on the chevron icon to open the command menu.

If you don't want to use ITs then go straight to Step  2
Step	Using the Gladstone Interlocking Tower  The first path to be set in this tutorial is from the Gladstone  Goods Loop  to  Broken Hill . On the Gladstone  page (link via - link will open in this window) this is identified on that page as:- From the open Driver Command Menu, select the  IT SetPath (TANE SP4 and later)  option. This will open a list of all the ITs that have been placed in the Session. Because an IT Starting Signal, in this case signal  GSX G27D IT Start , is directly in front of your loco, the signal will be included in the list of available ITs as shown below left. If no IT Starting Signal is directly ahead of your loco then only the available ITs will be listed, as shown below right. All Interlocking Tower Starting Signals have IT Start at the end of their names. All IT Starting Signals are invisible signals. Some have been placed directly in front of visible (semaphore) signals to prevent the IT paths locking the visible signals. Select the starting signal  GSX G27D IT Start . 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 . Every path is named according to its starting point (one of six "outside" locations or a track in the local yard) and its destination (one of six "outside" locations or a track in the local yard). The six "outside" locations are Port Pirie, Broken Hill, Terowie, Quorn, Wilmington and Peterborough. Those locations may not be the destination or starting point of the consist and they indicate the direction of travel only. 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 The path has now been set. All junction switches and signals along the selected path from the Start Signal ( GSX G27D IT Start ) 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. Once the path has been set, use the Driver Speed Dial, the keyboard controls (W, S, X), advanced on screen controls, or the AI to drive the train out of Gladstone Yard to Caltowie. Step  2  below explains this process. If you are using the manual driving controls (either the keyboard or on-screen cab controls) then it is a good idea to test the train direction first by clicking the Train Direction Button in the lower right of the screen. This will set and reveal the red and green direction arrows on the consist and establish the forward direction of travel.  Cancelling a Set IT 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 IT then a set path can be cancelled. From the Driver Command Menu select the IT CancelEnhancedPath command. You will have the option of cancelling ALL PATHS or selecting a particular IT and path to cancel.

Step	Driving From Gladstone to Caltowie  There is a minor location, Yangya, between Gladstone and Caltowie but it has no IT, minimal yard infrastructure, no visible signals and its switches are set for the main line through to Caltowie You have two options for driving to Caltowie - Manual and AI control.   Manual Control  You can manually drive the train through to Caltowie without using the AI Driver Commands. This requires that all the switches along the path are correctly set. You can do this by manually using the information on the Gladstone  page (link via - link will open in this window). 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 (W, S, X) 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. 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 (see   AI Control  below) as a stopping guide when you are driving manually When using the manual driving controls (either the keyboard or on-screen cab controls) it is a good idea to test the train direction first by clicking the Train Direction Button in the lower right of the screen. This will set and reveal the red and green direction arrows on the consist and establish the forward direction of travel.   AI Control  You can also drive by adding AI Driver Commands directly into the Driver Command Bar on the bottom right of the screen. The commands will automatically set all the switches along your path in the route. 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  Track Marks added to allow you to let the AI do most of the driving work. Apart from the standard commands (Drive To, Load, Unload, Couple, Wait For, etc), additional commands have been added to the session. Specifically:- 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 Track Marks are shown on the Caltowie  page (link via - link will open in this window). 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 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. From the Driver Command Menu select the command  Drive To Trackmark  then find and select the track mark  Caltowie Main Approach Dn .

If you don't want to use ITs then go straight to Step  4
Step	Using the Caltowie Interlocking Tower  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. A through path is the best option.   You can set an IT path without having to be directly in front of a Starting Signal. For example, you can set all the IT paths for the train through Caltowie and into Jamestown before you even leave Gladstone. To set a path for a distant IT, open the Driver Command Menu and select the  IT SetPath (TANE SP4 and later)  option. Then select the required IT and path from the lists. This can be repeated for as many ITs as needed along the path of the train. Open the Driver Command Menu and select the  IT SetPath (TANE SP4 and later)  option. Then select the  Caltowie Interlocking Tower . This will open a list of ALL the IT paths controlled by the Caltowie IT, including any paths that will not be directly accessable to your consist. On the Caltowie  page (link via - link will open in this window) the path we will select is identified as:- 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. 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  path 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 IT Start  will appear in the IT list. Select  Caltowie Home Dn IT Start . 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 . Path via Caltowie Station Once the path has been set, use the Driver Speed Dial, the keyboard controls (W, S, X), advanced on screen controls, or the AI to drive the train through Caltowie Yard to Jamestown. Step  4  below explains this process.

Step	Driving Through Caltowie to Jamestown  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. A through path is the best option.   Manual Control  To manually drive the train through Caltowie to Jamestown you will have to manually set all the switches yourself using the information on the Caltowie  page (link via - link will open in this window). 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 Once the switches have been set, use the Driver Speed Dial, the keyboard controls (W, S, X), advanced on screen controls, or the AI to drive the train through Caltowie.  Catchpoints  Notice that the Switch Track Diagram above shows three switches in red with letters as IDs -  A    B    C . These special switches are identified on the Caltowie  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. 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. 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 have set the path through a yard using the IT option or are using the AI Drive commands to navigate a yard, then any  Catchpoints  along the path of your train will be automatically set to allow the train to safely pass.     The Catchpoints used in major yards have mechanical indicators. Smaller yards use a simplier version with a static sign. The Catchpoint switch green arrow MUST point to the opposite side of the track from the Catchpoint Rail for the train to safely pass.   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  page (link via - 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.   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). 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 The  page at each location () 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.

If you don't want to use ITs then go straight to Step  6
Step	Using the Jamestown Interlocking Tower  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  page (link via - link will open in this window) shows all the IT paths into and out of Jamestown. The Jamestown  page identifies the path as 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  Jamestown Interlocking Tower  will appear in the IT list. Select this IT. 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 Start Signal  Jamestown Home Dn IT Start  will appear in the IT list. Select this Start Signal. In either case, the path name  Port Pirie to Loop  will appear in the list of available or assigned paths. Select this path. The path has now been set All that remains now is to use the Driver Speed Dial, the keyboard controls (W, S, X), advanced on screen controls or the AI to drive the train into Jamestown  Loop  and halt at the end of the loop. Step  6  below explains this process. This ends the tutorial but you can continue the Gladstone-Peterborough Depot Fuel Scenario.

Step	Driving into Jamestown  Jamestown is the final destination of this tutorial but the Gladstone-Peterborough Depot Fuel Scenario continues on to Peterborough. We will be using the  Loop  road as the destination in Jamestown.   Manual Control  As at Gladstone and Caltowie, all the switches will have to be set manually. The Jamestown  page (link via - link will open in this window) shows all the switches into Jamestown and their settings. The required Switch Set is identified on the Jamestown  page as Use the Driver Speed Dial, the keyboard controls (W, S, X) or the advanced on screen controls to drive the train into Jamestown  Loop  and halt at the end of the loop.   AI Control  The Jamestown  page (link via - link will open in this window) shows all the Jamestown track marks. The important Track Marks for this tutorial scenario are identified on the Jamestown  page as From the open Driver Command Menu select the  Drive To Trackmark  command which will open up a long alphabetical list of track marks. Find and select the track mark  Jamestown Loop Dn . This ends the tutorial but you can continue the Gladstone-Peterborough Depot Fuel Scenario.
