@Seo-onDaddy Why don't you use Lithium PowerFunctions lookalikes/clones like the CADA Lithium ion battery box (500 mAh, 7.4V)? It has half the capacity of the LEGO PF 8878 but with the rotary dumper and crane loader it should last 2 hours and is also lighter than batteries. I'm not sure if you can use it without the remote though as I use PF 8878. Mould King also has a Lithium battery box. LEGO PF is discontinued and for GBC it is okay to use 3rd party components to keep the GBCs going. You can also charge the batteries while in the train so you don't have to take the trains apart every time. I have four trains and when fully charged at the start of the day they will last an event day of 7 hours.

If you can't get them I would alter a cheap LEGO standard battery box and put the 2-cell lithium polymer battery (1500 mAh) in as you suggest. 1500mAh will not be enough for a full event day with the Rotary Dumper and Crane loader but just a few hours short.

Also take some spare motors with you. The M-motor doesn't like to be switched every time and lasts about 50 hours in my trains. Also there it is okay to use 3rd party like Mould King.

I use dry Teflon PTFE to lubricate. I don't spray on the LEGO parts but use a small brush to apply the teflon where needed and spray in a cup first. I also lubricate the liftarms/beams where the train is dragged over and the underside of the train but it must be cleaned and re-applied before a show. All small things helps battery life.

Good luck with your show and post a video here to show your setup. 

  

 

Hello.
I safely displayed Akiyuki's Train System at the Korea Brick Party 2024.

There was no problem with the whole system when I tested it at home, but the problem of leaving the track continued when passing through the revolving track on the day of the exhibition, so I removed the passing unit, crossover type, through unit, etc., and only the loader, unloader, elevator, and rotary damper were operated.

The cart used 1 lithium polymer version and 3 AA battery types, and the AA battery type was replaced only once on the second day, and it worked well throughout the event.

The elevator applied the frame and weight of 'MajklSpajkl', and the mechanism of 'Berthil'. The worm gear was too slow.

The Rotary Dampers were made in a version of 'Doug72', and the Loader and Unloader were made in a version of Akiyuki.

Regarding Pneumatic module. (this question may be suited for the Akiyuki project)
I have built it and run it for over 10 show days before replacing any of the moving parts. These parts where initially lubricated with some silicone oil, and I didnt have any issues at all. I think the parts could have gone for longer, but I didnt want it to be a hassle at my latest show so I changed out the parts. It is a bit of a its definitely a public favorite. 
The trick is low speed operation, run more pumps in parallel at less speed. 
 

Great advise, I am going to rebuild and lubricate. But the air I will definitely try.  4 small pumps you think?

For this module, how it is in the instructions is mostly fine. 2 pumps are enough. However I did 2 other changes. msg me for details (I dont want to put it in this thread as its not meant for here). 

Great work @Seo-onDaddy.

Correct should be as in photo.

Just curious if instructions for this version were ever generated?

@Seo-onDaddy Nice layout!

This weekend I've run the Crane Loader for a full event day without any issues. The train with the rechargeable PF battery worked for 5 hours straight with the Crane Loader. My tweaked Rotary Dumper also worked great. Many positive comments on this public LUG event day with 600 visitors without fences at the exhibition tables. For LEGO World in October I plan to do more with the trains. A digital design for a 6-arm robot to work together with the trains is ready which I will build after LEGO World.

Yep.

You can also revert this to the AA battery pack. Some older details are here https://bricksafe.com/pages/Jude_The_Lego_Dude/my-gbc-modules/misc-type-2-train

@Berthil Looking forward to seeing this robot arm. EV3 or mechanical? 

This is a note for anyone who may be reading this thread in the future. You will find all the bricksafe links I have posed (to date) no longer work. This is due to me deleting my entire bricksafe due to a security risk. Pls contact me if you are searching for instructions or CAD or part lists or whatever, I will find it in my archive and re upload it for you.

PoweredUp and Mindstorms 51515 hub and motors with Pybricks. I'm planning on controlling it manually with three train remotes and automate later in the train layout.

Finished free instructions for my GBC Type 2 train loader which has been working well for about 20 event days.

I'm working on a 6-axis robot arm that will lift off the container from the train to empty it. When finished I will have 3 train loader/unloader combinations.
