GN15 Heavy Duty Mining Wagon – Frequently Asked Questions

What exactly do I receive with this GN15 wagon kit?

Your order includes four grey resin-printed pieces: one bogie frame, one heavy duty mining wagon body, and two coupling blocks. If you choose the wheels-included option, you also receive two sets of 12.5 mm diameter wheels. All parts arrive unassembled, unprimed, and unpainted, with supports removed and the resin cleaned and cured by hand.

Is this wagon suitable for GN15 layouts only?

The wagon is designed specifically with GN15 operations in mind, particularly for moving rocks and heavy minerals. While experienced modellers may adapt it to other uses, its proportions, reinforced structure, and banded top are intended for GN15 narrow gauge layouts.

Does the kit always include wheels?

No, wheels are optional. You can choose to buy the kit with two sets of 12.5 mm Bachmann-style wheelsets, or without wheels if you already have suitable 12.5 mm wheelsets in your spares box. The higher price option reflects the cost of the included wheelsets.

What material are the parts made from?

All parts are 3D printed in resin and supplied in grey. They are cleaned, cured, and have their supports removed before packing. Resin gives you crisp detail but needs a little care in handling, as it can be delicate if dropped or stressed.

Is the wagon ready to run straight out of the box?

The wagon is supplied as a kit. You will need to assemble the resin parts, fit the coupling blocks and wheelsets (if purchased), and then prime and paint the model. Once assembled and painted, it is ready to be added to your GN15 layout.

What kind of loads is this wagon intended to carry on the layout?

This wagon is designed as a heavy duty mining wagon for GN15 layouts, ideal for representing loads such as rocks, ore, and other heavy minerals. The reinforced structure, banding on the top, and slightly longer length are all intended to give it a robust, industrial mining feel on your layout.

The wagon rocks or derails on the track. What should I check first?

Start by checking wheel and track basics:

• Ensure both 12.5 mm wheelsets are fully seated and turning freely in the bogie frame.
• Check that the wagon sits level and that all wheels touch the rails.
• Inspect your track for tight curves, kinks, or uneven joints that might catch the flanges.
• Make sure no resin flash or paint is obstructing the wheel bearings.

Small adjustments to wheel seating and a quick track check usually solve running issues.

The wheels feel stiff after assembly. How can I improve the rolling?

Stiff wheels are often due to tight bearing points or a little excess resin or paint:

• Remove the wheelsets and gently clear any residue from the axle holes or slots in the bogie frame.
• Reinsert the wheelsets, making sure they are straight and not forced in at an angle.
• Avoid over-tightening any added fixings or squeezing the frame when gluing nearby parts.

The wheels should spin freely with a light finger push once everything is cleaned up.

I can see faint support marks on the resin parts. Is this normal?

Yes, very fine support marks can remain even after careful removal. We do our best to remove supports, but a little light sanding is sometimes needed for a perfectly smooth finish. Use fine-grit sanding sticks or paper and take it slowly to preserve surface detail.

A part arrived broken in the post. What should I do?

If a part is damaged during shipping, please take clear photos of the breakage and contact the seller. While we cannot be responsible for damage caused after delivery, we will always do our best to help if something has clearly been broken in transit.

I accidentally broke a resin part while handling it. Can it be repaired?

Resin can be delicate, especially at thinner sections. Small breaks can often be repaired with a suitable modelling adhesive and careful alignment, but we cannot be held responsible for accidental damage once the item has arrived. If you are unsure how to repair it, contact the seller with photos for advice on the best approach.

How do I assemble the wagon parts?

Assembly is straightforward, even if you are new to resin kits:

• Test-fit the bogie frame, wagon body, and coupling blocks without glue to understand how they locate.
• Once happy with the fit, glue the parts together using a suitable adhesive for resin.
• Allow the joints to fully cure before fitting the wheelsets and handling the model extensively.

Dry-fitting first helps you spot any small areas that might need a light sand for a perfect join.

Do I need to clean the resin parts before painting?

The parts are supplied cleaned and cured, with supports removed, so they are ready for you to prime and paint. However, many modellers like to give resin parts a quick rinse in mild soapy water and let them dry thoroughly before priming, just to ensure the best possible paint adhesion.

How should I prime and paint the wagon?

The wagon comes unprimed and unpainted, so you can finish it to suit your layout. In general:

• Apply a suitable primer for resin to all parts, in thin, even coats.
• Once the primer is dry, paint with your preferred model paints in layers rather than one heavy coat.
• Weathering powders, washes, and dry-brushing work very well to bring out the mining wagon’s reinforced structure and banding.

Always let each layer dry fully before moving on to the next.

Can I sand or modify the resin parts?

Yes, the resin can be lightly sanded and carefully modified. Fine sanding is especially useful for removing any remaining support marks or improving joins. Just take care not to over-sand edges or thin sections, as resin can be brittle if stressed too much.

Any tips for handling and storing the wagon before and after painting?

Because resin can be delicate, handle the parts by the thicker sections and avoid bending thin edges or details. Try not to drop the pieces, and store them in a padded box or tray while you work. After painting, let the model cure fully before putting it into regular use on your layout to protect the finish and the resin parts.
