Configuring Train Yards

First off, what is the purpose for the yard, is it for interchange or is it for local industry, will it have an engine service facility, car repair shop, steam or diesel or transition area. How many trains will terminate/originate from this yard. Get out a piece of paper and do the figures. A yard that does not function will soon loose interest and so will the route.

It's a multi-purpose use yard. Over 16 trains a day on average terminate and originate out of this yard. It has a workshop on the west end of the yard. This setting takes place in the summer of 2012. The yard is also used for breaking down train cars to be switched and stored in the yard and then used to assemble a local train for the industries in the area. It's often filled to capacity. Hopefully this answer those questions.
 
If you are interested in creating prototypical operations, I'd recommend you come up with a transportation plan for the route. There are a lot of good
resources at http://www.opsig.org/ that will help you figure this out.

Once the overall plan for the route is understood, then you can define the functions needed in the yard, which will act as guidelines for how it should be structured.

If you don't care about prototype ops, then do whatever you want. Some will like it, most who value prototype ops will probably not be impressed.

I wonder why you would need all the crossovers. A properly managed yard does not store cars and then pull them as needed. It sorts cars as they arrive and put them into the next train that will be headed in the proper direction. So, each track in the yard represents a destination or group of destinations in a general area. As a train arrives, the cars in that train are sorted or "classified" by destination. Depending on you operation plan, an outbound train will be made up either at a specific time, or when a sufficient number of cars have been accumulated. There a books written on yard operations, so please don't think that this short explanation tell the whole story.

As for using AI, I have been quite successful creating a rather complex prototype yard, using AI to bring in all the inbound trains and also to take away the outbound trains. This yard has 26 classification tracks, three arrival tracks for southbound and three arrival tracks for northbound. It includes an engine facility with turntable and roundhouse. It also uses an AI driver to pick up the cabooses from the arrival tracks and store them on the caboose track.

Best of luck with your venture.

​I was storing the cars and pulling them as needed because I wanted it to look neat and orderly.
 
Fill a 30 track yard with more than 4 trains and your framerates will be a slide show ... Fill it to capacity, and your PC will lock up, as your video card can not handle seeing that many assets.

You can place fake railcar splines (trainloads of hoppers or boxcars) and the yard would appear full, but they are not drivable.

Seldom is a yard totally chock full of railcars, that's called gridlock, which requires a "Stand Down".

I thought gridlock was over capacity. Considering my laptop, it just might pose a problem. Hopefully in the future I can get an Alienware system so I don't have to worry about it.

Don't count on it. Even TRZ2004 carried a warning that you could crash even the most modern computer. I do not think that warning ought to be removed.

But for what it's worth to everyone, It's YOUR railroad and no one else's.
 
Cars are usually stored away from the yard, usually on an abondoned section of track. If a yard is more than 70% - 75% full, you begin to suffer gridlock. A yard needs to be fluid in its operations.

As far as frame rates and yard size, a bit of that depends on the speed and size of your graphics card. I model the Soo Line Schillar Park Yard, with over 300 cars or more in the yard at one time and have not had frame rate problems.

To be entirely honest, I got that info from manufacturers of specialty track bolts at Railway Interchange this past September. I did not know any better before then, but now, having spoken to industry experts, I hold my statement to be accurate.
 
What was the Canadian route that came with 04? It was a huge yard. I remember how hard it was to find a route form one side to the other.

I suggest that you study an actual/particular prototype yard, instead of trying to re-invent the railroad the way your mind see's how things should or might have been ... as this is not the way things are in real life (in the real world) ... very unprototypical looking.

Most RR's do not have 100 locos ready and waiting for service, some loco consists must be cut off of other trains, or called for, and run light in multiple units from distant cities. Some trains are late due to no locos, or no crews available.

A train rolls into a receiving yard, and the locos decouple and go to service tracks, or go to distant cities, or attach to already made up new trains. Incomming recieving trains must be classified (broken down onto many different departure tracks). Clean up switcher loco crews usually shuffle cars and trains down a hump yard, over night. A train may wait in a departure yard for several days (or longer) before it gets engines attached.

Usually only high priority trains such as perishable produce get 2 day guaranteed service between LA and NY.

Long distance passenger trains in the US are very sparse schedules, as there are not many left today

Here's a small through yard.

This is an overhead view of the same yard I posted before.

I agree the best way to create a decent yard is to copy something the prototype has already created. Being the prototype, they've done all the hard work so it's easier to copy what's already been done.

Well I suck ass at sketching but I found something that'd be of great help: https://rdl.train.army.mil/catalog/...-19CB6793D54F-1274315874429/4-01.41/chap6.htm

I'm not a good artist so I won't even bother trying even somewhat emulate that but I'm sure you'd be understanding. The real deal hopefully will look something like that.
 
I hate to step in on this as an official capacity but you need to be careful posting military Field manuals. Some are for public distribution and some are not. Posting those that are not can lead to repercussions. The above Link to the pages of FM 4.01.41 is good. Distribution Unlimited / approved for public release. The FM is on Army Rail operations.

A yard should be built to meet the needs of the railroad. Every railroad, even an imaginary one should have a transportation plan - it will help you define what a yard on your railroad should look like and how it should function. Books have been written on the topic of yards and freight operations. My favorite is Freight Terminals & Trains by John A. Droege. You are looking for a simple answer to a complex question. The answer lies in you doing some research if you want prototypical yards.

If the Army didn't want this to be classified, then I'm pretty sure they would NOT have posted this manual on the web. They would also would've said on the page, not public distribution. Then again, it's the #NewArmy so you never know what's going to happen but I doubt a stupid train yard diagram is going to make them throw a **** fit and have a cow as they have much more serious matters to deal with, but like I said, they can and have been very petty and anal about their tactics and the way they go about doing things in the New Army.
