"I would like to see a trailer go from a flatcar to a holding lot next to the track instead of it just disappearing if possible."
What I mean is I would like for the trailer to disappear from the flatcar & then appear in the holding lot like some trainz companies do with other products instead of the trailers just... disappearing & you having... to right click on the track to find out if there are any trailers there when the company still has 100 of them. (If the trailers appeared in the holding lot you wouldn't have to right click on the company to find out if trailers were there because a percentage of them would been showing.)
"If this is possible my problem is while I know how to give a company that already has the ability to unload a product off cars the ability to unload an additional product off them, I don't know how to give a company that doesn't already have the ability to unload a product off cars the ability to unload something off them."
What I was saying here is, I know that when you are in, "Manage Content," & right click on something you can then click on, "Edit," & then, "Edit in Exployer." After you do this if you click on, "config.txt," you can look & see if the word, "queues," is listed, if it is & has something that the crane is capable of moving listed then I know you can add something else to the list & the crane will also move it. But if I click on, "config.txt," & the word, "queues," is not listed (in other words the crane does not already have the ability to move something) then I don't know how to give it that ability.
Mike, I believe you're describing the, "HP Intermodel," which is built in to the game. Thanks for trying to help me though.
