 This is a simple card system that I use for my layout. The key to this system is we do not look for card numbers at all. We treat a box car pretty much as a box car and a flat pretty much as a flat as a tank and so on. So let's show you how this works. This is what I call a starting card. As you see on it, it says S1. That's for scenario one. Every operating session is set up as a scenario and a scenario consists of about ten cards and of those cards, three will be for yard work and seven will be for road work. In this particular card, if you look at it, it has businesses down the center that my layout serves and the first row says start of S1 and that is a list of all the cars that need to be at those businesses in order to start this scenario. Now, my scenarios follow one another so where S1 stops, S2 would begin and you don't have to choose to set yours up that way but that's what I've chosen to do on mine. Each scenario takes about three hours to operate which is just about right for a group of guys. This is a typical yard card. If you look down it says S1, Y1. So that's just a scenario one yard card one and so if we go up to the top, it just states that it's yard work. You can pick any engine. You do not need a caboose and the yard work that it's in is west yard. Then if you take a look, this is a typical one for building trains. It says build train O3 down then O4 and then O5. It tells you the list of the cars that are needed to build that train and then notify the dispatcher whenever it's finished. Once the dispatcher is notified then it transfers to a road card. The road crew would then come and pick it up and head out to deliver the cars. So we are going to build train O3 or at least part of it. Some of it's already done as you'll see. As you look at it, it needs two flats of lumber, one box of lumber, one gondola steel, two small tanks and seven grains. We're not concerned with any numbers. We're just concerned with the two flats need to have lumber on them, one box car needs to say something on the side related to lumber and the gondola needs to have steel in it. The grain cars and the tank cars are just whichever small tanks and whichever grain cars we want to choose. On the back side, we see that all it is is it says yard work. There is no delivery destinations and there are no deliveries done with this particular card. So let's go ahead and finish building train O3 so it's ready for the road. This is the TJ&H main yard. We have an inbound and outbound side. The inbound side is close to us. Here we see train O3, the two flats of lumber and a caboose. We're going to finish building that as you watch. One gun of steel, two small tank cars and one box car of lumber being added to the train. The yard crew is heading to the inbound side of the yard to pick up seven grain cars and add them to train O3. When that task is done, the train will be ready to leave the yard. Build up a little air and let's go. The yard crew will get out of the way and allow the road crew to come pick up the train and they'll be off. Here's train O3 ready for the road crew. Seven grain hoppers, one gondola steel, two small tanks, one box car of lumber, two flats of lumber and a caboose. Ready to go. And here's the road crew getting ready to hook up to the train. They will pump up some air and get ready to go. This is the card that they'll be using to do their road work. This is S1C3 and all it says on the orders is switch cars to the destinations noted on the other side of this card. If we look at the back, the very first destination is Paws Lumber. That's where we're headed. Here we are at Paws Lumber, the second destination on our list. Here we will deliver one box car of lumber and two flats of lumber and we will pick up two empty flat cars. These will be delivered to West Yard. At Paws Lumber the empties have been pulled and the full cars have been set in the yard. We're now ready to hook back up to the train and head to our next destination. We're at Three Mile Co-op the second destination on our card. Here we will deliver seven empty grain hoppers and we will pick up eight full grain hoppers. The full grain hoppers will be delivered to West Yard. First on the agenda, pull out all the full hoppers. With the full cars pulled from the yard we can now back in the empties. With the work done at Three Mile Co-op we can now hook the train back together and move to our next destination. Here we are at BD Fire Systems our third destination on the card. Here we will deliver one gondola of steel and two small tanks. We will pick up two empty small tanks and one empty gondola. Those will be taken to West Yard. This concludes all the switching that's on this card. The only thing left is to take this train down to West Yard so it can be made up into other trains. Here we are at West Yard. We will be pulling into the inbound side of West Yard and there on the outbound side we see train 04 ready for us. This concludes this card as written.
