Steve,


On my new ERIE template I have a path that starts in one yard "A" travels to another yard "B" by backing around a "Y" so the locos are facing foward back towards "A" the path starts and ends in yard "A". The path works with 2 reverse points. I can get AG to generate pickups and setouts for the yards and a powerplant that is along the way. What I can't get is to pick up at "A", set out at "B" pick up addtional work at "B" and return to "A". I have yard and industry tracks in both yards. Is there a way to "trick" the program to get this to work or am I asking too mutch?


This is not a show stopper on releasing my new template as I have 4 paths that work and cover all the tracks with overlap. 


Thanks,


Peter

Steve and I have discussed this very issue, i.e. that of picking up intermediate work at places, especially yards, along the player path.  This is particularly important for a "turn" type of freight. 


The current program algorithm assumes that all set outs will be in the starting trains and all pick ups will be in the final train.  Thus for your turn, the program can possibly pick up cars at B as described, but they would not be for set out along the turn's path.  (I say possibly because the randomizer might not select any cars at B, or any other point along the path.) 


It is possible to set up an activity with cars starting at A, set out some on the way out, turn and pick up cars at B, then set out more on the way back.  I have published at least one AG generated activity which does this (for Shuswap).  But all set out cars will originate at A, either in the train or for pick up at A.


As an aside, the path for a turn does not have to include the turning wye, although it can.  You could simply design a path with a single reverse point.  If the route's track switches are manual, then the player can choose to use the wye -- or not.  Even if the route's track switches are not manual, then AG can convert the track switches to manual, and once again the player can choose to use the wye -- or not.  In these days of MSTSbin, the ability for the player to move to the trailing engine more or less negates the need to use a wye, especially when using diesel motive power.


Consequently, to actually simulate a turn with this type of work would really require two activities -- one out, one back.  The difficulty here is in making the second train an exact duplicate of the ending train from the first activity.  Currently this is all but impossible, but Steve has contemplated varioius ways to do it.  The MSTS save function is unfortunately not in unicode, which would make it easy, so it might turn out that AG would have to write an ending consist file when it completes an activity, which file could transfer the consist information to the starting train of the next activity.  There are some reasons to want this continuing consist for many types of trains, but this solution (the two part train) is not the best for a turn.


So the short answer is that AG currently does not allow for picking up cars at intermediate points and then setting out those intermediate cars along the way.  I am hopeful that someday we might see this feature inplemented.

Norman,


Thanks for the answer, the current switch lists and paths on this template with default settings some times takes hrs to complete in the current configuration and should be sufficient for any one that likes to switch cars. This option would have only add a different twist to the working the list.

Peter,


I am hopeful that you will share this template with the AG/MSTS community here on the Skyline web site.


BTW, what route is this?

I agree that's a problem with the current version of ActivityGenerator.  The workaround for now is to end with the "AssembleTrain" function.  Then, what you do is set the first yard (where you start) as "source" tracks and all the other tracks, including yard B, as "Industry" tracks.  Then you'll have to assemble your train to end the activity, just go back to yard A and assemble your train, which will include all the pickups you've made along the way including those in yard B, and you will have your turn.


The better solution is what I have planned for Activity Generator v4, which I probably won't get done until the summer.  In that version there will be a third type of track (beyond "Source" and "Work") called "Destination".  Tracks you call up as "Destination" will require setouts of any cars picked up along the way.  This will work for turns and also for through trains so you'll have somewhere to set out the cars you've picked up along the way.


Thanks!


Steve

Norman,


The Erie template is for the Newark & Jersey City Route. It will provide work from North and South Croxton yards east to  Jersey Terminal then north to the Erie Weehawken class yard and the Erie piers. 


There is a side run to a powerplant and a yard half way between Croxton and Weehawken is Monmouth Street yard, this yard is fun to switch as the yard is on a grade and heavy working of your brakes and lots of sand is needed to prevent runaways. 


Yes I will post it as soon as I run some more switchlists to get the bugs out.


Peter

Peter,


Wonderful!  I really like this route, especially since it has myriad switching possibilities.  


Like the Lehigh Valley route, NNJ includes many different RR's, and thus realistically should be covered by many templates.  Several templates are already available, and I am glad that more are being created.


I look forward to  many enjoyable hours of operation on the Erie portion of NNJ using your template.
