Safety, small parts and magnets on wooden trains

What to check on wooden train sets for small parts, magnets, hinges and edges, how age grading follows the smallest part, and how report status works per model.

A toy train has three failure modes that matter for safety: parts that come off, magnets that come out, and edges that are not finished. None of them shows in a catalogue photo, and all of them are checkable on a sample.

Small parts

A train set is full of small pieces: signals, figures, signs, coupling pins. The age grading follows the smallest part that a child can detach, not the largest. A 3+ set can contain small parts; an 18M+ set must not. Where a set mixes a chunky pull-along train with small scenery, the grading follows the scenery.

Test the small parts on the sample: pull signs and figures, check screw covers and plugs, and check whether a part that is meant to be fixed becomes loose with use.

Magnets

Magnetic couplings are the most common failure on cheap engines. A magnet that escapes its housing is a serious hazard. Check on the sample: the magnet is enclosed, cannot be levered out with a fingernail, and holds under load. Ask whether the magnet is specified in the test report.

Hinges and moving parts

Station doors, crane arms, lift bridges and signal arms are hinge points. Check the gap, the finger traps and the fixing. Moving parts should return without pinching and should not come apart in normal play.

Edges and finish

Sanded edges, rounded corners and a sealed finish are the basics. Check the underside and the track ends, which are the easiest places to leave a rough cut. Paint should not chip at the corners; a chipped corner is an exposed edge and a recall risk on an infant product.

Age grading

18M+: chunky, no detachable small parts, no magnets that can escape.
3+: small parts allowed, magnets allowed if enclosed, warnings stated.
6+/8+: model and hobby ranges, different labelling again.

The listing should state the age band and the reason for it; the report should cover the model and the market. A report for a different model in the same range does not cover the one you are buying.

Report status

Ask per model and per market: does a report exist, or does it have to be commissioned? Who commissions it, who holds it, and what model list is covered. Agree this before the first production run, because retrofitting a test to a finished production batch costs more than designing for it.
