Question about Industry unload

[Apogee10]

Is it possible to drive a consist to an industry and unload only 1 car. I would like to drive a consist to Goods shed no 1 and unload car no 1, drive to goods shed no 2 and unload car no 2, etc. This seems like a simple thing to do but I can't figure out how to set it up. Any help is appreciated.

You could uncouple the all the consist except the car you wish to unload, leave that at the industry siding, recouple with the rest of the consist and move on to the next industry.

Industry

Don't know what good shed you are using but if you use any of the LARS/PROTO LARS INDs you can set them to unload only 1 product or up to 256. The G2 Goods shed are the same way kuid:61119:28036>

The easiest way is to "lock" the loading or unloading of each car. For this, when in a session, go to the commodities panel and select the red X at the bottom of all the commodities. Then click on a car so that the X shows on it when the mouse is there. Now that car will not unload or load when at the loading track. When you want to allow it to load, just do the same with the arrow (next to the X) or any commodity in the list (if the car accepts it). Once you get the hang of it, is easy and comes naturally.

Thanks for the replies. I am using Goods Shed Ind, kuid 1942:27020, but would change if there is an interactive object that will accomplish what I want to do. I am only carrying one product, general goods. I have one consist that must make several stops and unload a set number at each stop, not the entire consist. I was hoping there was a way to tell an AI driver to unload a limited number of goods at each stop. It could be just one car. Then go to the next station and repeat.

Hi Earl - Some totally untested and spontaneous thoughts! Maybe if you set your unloading points to consume/receive rather infrequently; create a track marker for each unloading point; tell your train to go to each track marker and wait a few seconds? A little convoluted maybe but it just might come together for you!

Have fun.

Thanks Colin

A novel idea. If I correctly understand your idea, I can limit the time the consist sits at the unload station. By trial and error I can set a Trackmark such that certain cars sit on the station and after a few seconds drive to the next station and set the TM such that the second set of cars stop at the station. I will experiment and report back.

I'm still curious if a script couldn't be written or modified to do this. If I have 10 cars in the consist, I could number them from 1 to 10 starting at the loco. The script could unload car 1 at station 1, car 2 at station 2, etc

Hi Earl

I think you can pretty much guarantee that a script could be written ..... but who has both the ability and the inclination?????

Re my idea: The only obvious bit of tinkering required is getting the train to stop such that the appropriate wagon is unloaded. The track markers must therefore be placed progressively further away from the actual unloading areas. On the downside of course, if you start monkeying with your train length and/or wagon size it may impact the accuracy. A change in loco length and/or braking ability will also impact it. Finally, you will also have to instruct the train to go your markers rather than to the industries!

The more I think about it, the more I think there has to be another way!!!!!!!!!!

Have fun.

ps re scripting. The cars are already numbered by the system as it allows uncoupling a specified wagon in a train.

Hi Colin

I experimented with your suggestion and met with partial success. I set up a section of track with Goods Shed Small Ind. I added a consist with 5 loaded cars. I placed a TM near the shed ( I had to adjust it by trial and error) and set up the consist to run AI. The commands were Drive to TM shed, unload, Drive to next TM.

In Driver the consist drove to the TM and the first car unloaded. The remaining cars stayed loaded. However, the AI driver couldn't continue because the Unload command never finished(there must be something in the command that requires all cars to be unloaded). While still in Driver I manually removed the Unload command after the first car unloaded and the AI driver continued on his way.

So, this method will work but requires some manual intervention to assist the AI driver.

At least we have a start. I will continue to experiment. I'm going to look at the Unload script to see if there is a minor change that can be made.

If you have other ideas I will try them.

Hi Earl - Do you have to tell the AI to unload??? Why can't you tell him to go to Goods Shed Track marker and wait 5 secs. As he has not had the unload instruction he is not going to wait, and as long as the Goods Shed is set to receive, then as soon as a wagon stops it will unload.

Trainz, or at least TS2010, seems to have a double standard with regard to unloading/loading without using the load/unload commands. If driving a train manually you should be able to stop a train at an industry, wait a couple seconds, and the cars in range will be loaded/unloaded appropriately. However if you try the same thing with an AI train using the Wait command then it will not work, even if you have the train sit there for a full 5 minutes.

LARS or ProtoLARS should be different though and may be the best solution to what the OP wants.

Thanks Edrickv

I will try a LARS or ProtoLARS industry and report back.

It works with LARS/ProtoLARS

EdrickV

I can do exactly what I want to do with a LARS/ProtoLARS industry. There are several nice features of these systems. (1) You don't have to have the car over a load/unload platform. As long as the consist is within the trigger it will unload starting with the first car. (2) You can set the industry to unload one car at a time and you can set the time delay between cars. (3) You can also set other time parameters that helps set the unloading sequence.

I experimented with a test setup. I ran the test and recorded the times for the events. Then I setup the AI driver and he drove away after the first car had unloaded. It's going to take some work to set the Trackmarks and Event Times but it's doable. I think after I work with it a little it's going to get easier and the timing will not be critical.

Thanks

Hi Earl

I just did exactly what you want with simply setting the max limits of the Industry. The train will not unload if the Industry is at max..... and it does not wait! In fairness, I only used 2 unloading points (both same asset) which took a max of 256 units. I set Unloading No 1 at 255 and the train co-operated by only unloading 1 item. I set Unloading No 2 also 255. Where this falls apart a little is (e.g.) 6 Unloading points where you are going to have to balance the Max against a Consumption rate, and factor in the time it takes the train to get there!

Thought it worth mentioning. :wave:

Colin.

PS Forget it! Just realised that it will only work for one pass of the train!

Hi Colin

I'm reporting back on my progress. I have the AI driver doing exactly what I want him to do.

He drives to the first station(I'm using PL lumberyard) and unloads the first car. He then drives to the second station and unloads the second car. And so on. It's easy to set up. The Trackmark placement is important but not critical. The LARS station will function as along as any car in the consist is within the trigger radius. Timing is also important but not critical either. The LARS station allows the timing between unloading each car to be adjusted.
This allows the AI driver time to unload and drive away. I'm currently using 15 sec between car unload but may change to 30 to have more margin. I also find it convenient to use the STOP TRAIN command following the Drive to Trackmark command to ensure unload.

Your last suggestion intrigues me because it would allow partial unloading or a car. I may experiment with it also.

You are correct in your statment but if you issue a stop command the unload will take place
