ᐅ Who uses their KALLAX for model railways – is the load capacity sufficient?

Hello everyone,

I have a question for the community involved with model railways and the IKEA KALLAX shelving unit as a storage and layout surface: Who uses their KALLAX shelves specifically for setting up a model railway or at least for storing tracks and trains? I am particularly interested in whether the load capacity of the KALLAX units—especially when placing tracks, trains, and possibly landscape elements or electronic components on multiple levels—is sufficient.

How do you handle this in practice? Are there any experiences regarding the load-bearing capacity, for example due to the weight of the materials? Do you need to reinforce or modify the shelving unit in any way?

So far, I have only found rough specifications from IKEA, which provide the load capacity per shelf panel, but I wonder how this works in practice for larger, integrated model railway setups.

Looking forward to your answers and experiences! Thanks in advance.

I used my KALLAX for a model railway and can say: The shelves hold up well if you distribute the load evenly. Reinforcement is usually not necessary as long as you don’t support heavy items at specific points.

Hey chenmeo, I also use my KALLAX for a small H0 (1:87 scale) model railway. I just paid attention to the load distribution and added some extra wooden slats – basically an upgrade 😎. It works easily, and even with landscape elements, it holds up really well. The load capacity is quite decent as long as you don’t overdo it. Have fun building! 🙂

I can approach this topic in detail since I have a KALLAX unit with a model railway setup myself.

According to IKEA, the KALLAX shelves can support a maximum of 13 kg (29 lbs) per shelf, but it’s important to consider that model railway layouts don’t just create point loads—they can distribute weight quite evenly, especially if the tracks and scenery are well assembled. For a larger layout, I recommend reinforcing the shelf panels. For example, using metal brackets underneath the shelves for stability or adding a cross brace between the shelving units.

A small tip: the panels are made of particleboard, so be careful with moisture—make sure they are well sealed. The KALLAX shelves themselves are about 12 mm (0.5 inches) thick, which isn’t very strong. For heavier sections, I would recommend adding extra wood supports.

It would be helpful to know the exact size of your project so that potential weak points can be assessed more accurately.

Thanks, that’s already helpful to hear so specifically.

My plan involves an HO scale model railway layout with a footprint of about 1.2 x 0.6 meters (4 x 2 feet), set up on two KALLAX shelves stacked vertically. The upper level will primarily be for the tracks and trains, while the lower level is intended for boxes and technical equipment.

I’m wondering if the 13 kg (29 lbs) per shelf capacity is enough, especially since the tracks along with the base and scenery can be quite heavy. Are there any practical tips on how to best distribute the load, or whether the cross braces really make a big difference? If anyone has built something like this before, a firsthand report would be great.

I would recommend distributing the load over several points and avoiding concentrated heavy equipment or landscaping. The KALLAX is suitable for smaller model railway projects, as long as the maximum of 13 kg (29 pounds) per shelf is not exceeded.
