This past week I have taken leave from scenic projects and track cleaning to research and make preparations for a loco upgrade and a modified card operating system. My car card/waybill research took me to this youtube of a "simple car card system" published in another model rr mag, model rr hobbyist. Tom Driscoll explains the system for his N scale operations as trains are built, then road switchers take the train to the destinations to drop cars off and pickup other cars. I won't try to restate the concept in any detail as the vidoe is well done, except to note that it involves treating a type of car (box, flat, gondola etc. with exceptions) as a generic type car as opposed to a specific car by road name and number.
After a lot of thought about operation time and complexities, (there are a lot of complexities!!!) I wrote up a few "train cards" to begin the experiment. I have made up preliminary designs for the cards but nothing worth showing yet. The more cards and logistics this involves for me, the more I may understand the various operation systems. It is a puzzle for sure, but fun for me.
Using this system, I am outlining 6 basic scenarios. I don't have to complete all or any part of a scenario. I can pause operations with a mere paper clip. At any time I can just run the passenger/mail trains, through freights and even switching trains without formal operations so long as I return the trains to the last spot.
The 6 scenarios will vary. I call them "Sessions" (S1, S2, S3 . . .) that involve making trains for switching; switching; making trains for through freight; running through freights; making passenger trains; running passenger trains; making fast mail trains; running fast mail trains; running the static oil tank train consist. The freights, passenger, mail and oil tank trains are alternatively run east/west bound to add variety. The operations in each session are identified on specific "Order" cards. My sessions always involve making freight trains for switching and switching. In addition, each session will involve two different "through trains", one EB and one WB. I have mixed them up as best I can at this point among the following types of trains as well as direction for through freight; through passenger; through mail; through oil tankers.
S1: "Yard Orders" card specifies (1.building freights for switching. 2. building freights for through trains, building passenger/mail trains . . .)
S1: "Switch Orders" card specifies (1. the delivery, hold or transfer of freight cars for industries on my layout. 2. Transfer of passenger/mail consists for road loco. 3. other transfers . . .
S1: "Road Orders" card specifies (1. direction, number of loops, stops for water, last spot at destination city for through freights, oil tankers and passenger/mail.)
S1: "Start Order-Freight" card specifies the businesses on the layout and the cars initially spotted at each business.
S1: "Start Order-Through Trains-Engines" card specifies the spots for those.
The idea as expressed my Mr. Driscoll is that each session will begin where the last ended as far as the spots for virtually all the locos and rolling stock except for specific cars. This is because, the system is based on a box car is a box car and a flat is a flat, not a specific road name and numbered car. The exception eg. might be for meat reefers. At the end of (S6), the types of freight cars at businesses will be the same as on the S1 start card. So, a start card is not necessary for each session.
My inspiration is others have commented that moving trains with some idea of operation, no matter how informal, should add interest to running the continual round about. I am still in the develoment stage of this but it is enjoyable so far. I don't yet have an idea on the time for a session so undoubtedly I will modify the plan. As in life, everything is subject to change.
