Re: Making a plant switcher work correctly #operationspro


 

Ok John,
?
I was holding off with a reply, figuring some help might be forthcoming.
?
Since this appears to be a rephrased post from the original question, I am guessing that you didn't get the results you are looking for, from the replies you received.
Let me see if I can offer a workable suggestion that addresses your want list from the original post. ?
?
The following suggestions create a basic approach to answer your issues. ?They involve all your stated tracks at ADM, but I use only the one other location for the Local train, which I call "Interchange". ?If you want to add more tracks or other locations to the Local's route, you can certainly do this, but my example needs only the one track in "Interchange".?
?
The key to all this interchange of cars is the correct track-type assignments and filters thereon. ?Here are my suggestions as well as images for how I set things up...
?
Locations: uses only 2
?
  • "Interchange" (image 1) - served by the Local train
    ? ? ?has a single Spur-type track called "Drawers" (image 2) which in turn has a Load Option filter (image 3) and uses a schedule called "Load Exchanger" (image 4)
    ?(this location's schedule is what converts your loads into MTYs and vice versa. ?It also assigns Grain Hopp cars that are MTY, to point only as far as ADM where the program then assigns them to either Pit 2 or 3)
  • "ADM Facility" (image 5) - served by both the Plant switcher and the Local train
    ? ?has 4 Spur-type tracks (listed in image 5), each with the direction boxes unchecked and allowing in only certain car types (images 6a-9a), while also using schedules (images 6b-9b)
    ? ?has 4 Yard-type tracks (image 10), again with unchecked direction boxes, allowing certain car types, and one (Track 7) with a Load Option filter (image 10a)
    ? ?has 2 Class/Interchnge-type tracks (image 11), one each for inbound/outbound cars, allowing only certain cars/loads and limiting which trains work which tracks (images 12a-b & 13a-b)
    (additionally, by limiting which destination can be served by the "Pass" track (image 12c), no cars are allowed to move from the inbound "Pass" track back to the outbound "Yard Lead" directly)
?
Car types: uses only 2 (no images, as you should know about cars and how to edit)
? ?
  • "Grain Hopp" - loads allowed = <Corn> and <DDG>, empty allowed = <MTY> (for my example, all grain cars can load either corn or DDG, which allows respots at ADM)
  • "Tank_C2H6O" - loads allowed = "Ethanol", empty allowed = <MTY>
?
Trains: ?uses only 2 (again, no images, 'cause see above about Cars)
?
  • "Local train" - uses the route called "Local" and serves both Locations (though limited to only certain tracks at ADM)
  • "Plant switcher" - uses the route called "ADM Plant" and serves only ADM (is a true "switcher" thus can work all tracks, including those with no direction boxes)
?
Routes: uses only 2 (images 14 & 15)
?
  • "Local" - used by the Local train and with 2 lines for each location (by allowing S/Os on the first line at "ADM" and P/Us on the second, the number of cars can be controlled)
  • "ADM Plant" - used by the Plant switcher and has only one line, allowing up to 50 moves.
?
Altogether, this example allowed me to build either train and see the movement results that I believe you stipulated in your post. ?One small hiccup being that occasionally, when an MTY Grain Hopp was sent to any of the Yard storage tracks (4-6), it could then sometimes be assigned to return to "Interchange" for loading with corn. ?This occured when no space was available at DDG loading when the Plant switcher was built. ?I can offer a small setup correction if you prefer this not happen, but I considered it a small offset to the overall working flow since the cars will move either way.
?
If any of this seems fuzzy, let me know and we'll defuzzify with more help...
?
Happy to help, hope it helps,
