How to specify a wooden railway range
A decision sequence for buyers specifying a wooden train range — channel, age band, gauge and connector, set architecture, packing, reports and reorder.
Specifying a railway range is a sequence of decisions, not a catalogue selection. The channel decides the shelf role, the shelf role decides the architecture, and the architecture decides the gauge, the carton and the report plan. Get the sequence wrong and the range becomes a pile of models that do not sell as a system.
This guide is the order of decisions used for this range. Each step points to the page where that part is documented in more detail, so a specification can be built and defended line by line.
1. Write the brief before the range
Start with a one-page brief. It is the document the range is measured against, and the fastest way to see when two parts of the specification contradict each other.
| Brief field | What to write | What it locks later |
|---|---|---|
| Channel | import, retail, online or education | shelf role and pack format |
| Band | entry, mid or top | piece count and packaging |
| Age | 18M+, 3+ or 6+ | small parts and warnings |
| System | gauge reference and connector family | refills and expansion |
| Architecture | anchor, refill, replacement | piece counts and cartons |
| Packing | carton, pallet, marketplace | set and table size |
| Reports | model list and markets | launch markets |
The brief has to fit on one page because it is read at the sample table. If a field cannot be filled without a question, the question belongs in the supplier enquiry.
2. Start from the channel
The channel decides what the range must do before it decides what it looks like. A distributor needs refills and replacements; a retailer needs shelf roles and packaging; an online seller needs carton and image data; a preschool needs small-part control and storage.
| Channel | Primary decision | Range shape |
|---|---|---|
| Import or distribution | system consistency | anchor, refills, replacements |
| Toy retail | planogram | anchor plus refill facing |
| Online | carton and listing data | compact pack, neutral box |
| Education | age band and storage | durable sets, spares, tables |
Each path has a page on this site: importers and distributors, toy retailers and chains, online sellers and preschools and daycares. Read the one that matches before choosing models, because it names the fields that matter for that channel.
3. Fix the age band before the artwork
The age band follows the smallest detachable part, not the style of the range. An 18M+ item has no small parts and no magnet that can escape; a 3+ set can contain small parts and must carry the warning. Mixing an 18M+ vehicle into a 3+ set is possible, but the set takes the older band and the manual has to say so.
Fix this before packaging artwork, because the band appears on the box, the manual and the report. The age grading guide covers the detail, and the safety guide covers the parts and magnets to check.
4. Decide the gauge and connector
The range needs one system: a gauge reference, a connector family and a rail profile. The 40 mm rail-centre figure is the standard reference for common wooden railway systems and the right starting point, but it is not the whole decision. The connector family decides whether pieces join, release and survive play; rail profile and track height decide whether a vehicle runs across the join.
| Decision | What to specify | Evidence to ask for |
|---|---|---|
| Gauge reference | 40 mm between rail centres | measurement per model, confirmed on sample |
| Connector family | peg-and-slot, magnetic or hook | connector drawing or a sample join |
| Rail profile | profile and track height | side-by-side comparison on a sample |
| Coupling | magnetic or hook, plus height | pull test on the sample |
Write the system decision into the brief once and use it to filter every model. A model that does not fit the system is not a range model, however well it sells alone. The compatibility guide explains the interfaces in order, and the gauge reference shows how to measure each one.
5. Design the set architecture
A range is an anchor plus a system around it. The anchor is a complete set; the system is the refills, replacements and add-ons that keep the anchor in use. Piece count matters less than piece mix: a set with switches, a bridge and two engines is a different product from a set of the same count in plain curves, and it supports a different refill plan.
| Role | Job in the range | Typical pack |
|---|---|---|
| Anchor | introduce the system | complete set with a loop |
| Refill | extend the layout | straight, curve and switch packs |
| Replacement | replace wear or loss | engine, carriage |
| Add-on | change the play | station, bridge, signal |
Decide the anchor, at least one refill and one replacement before the first sample order, because the connector decision has to cover all of them. The spare parts guide sets out the reorder structure.
6. Set the band structure
Bands should follow the shelf, not the catalogue. An entry band introduces the category, a mid band carries the gift purchase, and a top band carries the anchor and the table. Every band needs one anchor and one add-on, or it cannot be sold as a range. Cost moves with piece count, material, carton and packaging; the price band guide explains the structure without a price list.
7. Plan the carton and the container
The carton record is part of the specification, not an afterthought. For each model, record pieces per carton, packed dimensions and gross weight, then test the loading plan. Typical planning volumes are around 28 CBM for a 20GP and around 68 CBM for a 40HQ, both nominal, and a mixed container of sets, track and tables rarely loads like the sum of single-model plans.
Two decisions here are hard to reverse: whether the range includes tables, which are flat-packed and volume-heavy, and whether it includes display cartons, which are consumer-facing and weaker in transit. Both belong in the brief and both are cheaper to change before packaging is printed. The packing and container data page has the arithmetic, and the container loading guide covers load order.
8. Fix MOQ, samples and lead time
MOQ is per model, from 20 pcs on stocked models, with a new shape, piece mix or box quoted separately; these are typical and confirmed per model. Samples are where the specification becomes a physical product, so sign off the piece mix, finish, connector and box together rather than by email.
Lead time runs from artwork and sample sign-off, typically 25-45 days depending on the model and season; the quotation states the figure for the order. Book the first sample round before the season, not after the range is chosen. The MOQ and lead time guide covers each step.
9. Agree the report plan before production
A toy report is model-specific and market-specific. Before the first run, agree which models need a report, for which market, who commissions it and who holds the documents. EN 71 and ASTM F963 are the usual references for the EU and the US, with other markets adding their own labelling rules.
A report that covers a different model in the same range does not cover the model being bought. The quality page explains the report matrix, and the safety guide covers what the report should state.
10. Build the range matrix
The matrix is the one-page picture of the range: one row per model, with role, category, age band, system, pack format and report status. It doubles as the checklist for the first order.
| Column | What it records |
|---|---|
| Role | anchor, refill, replacement, add-on |
| Category | sets, track, engines, tables, scenery, pull-along, custom |
| Age band | 18M+, 3+, 6+ |
| System | gauge reference and connector family |
| Pack | carton, display, neutral, marketplace |
| Report | market and status |
A matrix with gaps is a range with gaps. Fill them with fewer models rather than with guesses. The benchmarks page gives the band-level view behind the matrix, and the guides index collects the detailed notes behind each step.
11. Plan the reorder line
The reorder is what makes the range profitable: a set is bought once, while track, engines and carriages are bought again. Decide which models are stocked year-round, which are seasonal and which are made to order, then confirm the reorder lead time for each. A range with no reorder line is a one-off order, not a range.
12. Map the season
Railway sets are a gift category, so the range has a selling window. Production has to be scheduled against the shipping peak, typically the third quarter, with the reorder decision taken early enough for a second run. Map the calendar backwards from the shelf date, not forwards from the sample date.
13. Write the specification sheet
The specification sheet is the document that goes to the supplier and comes back as a quotation. Fill it per model, not per category, and write confirmed per model where a field is still open.
| Field | Why it is on the sheet |
|---|---|
| Model and role | identity and position in the range |
| Size and pieces | shelf and band fit |
| Material and finish | durability and report scope |
| Gauge and connector | system consistency |
| Carton and weight | container plan |
| MOQ and lead time | order shape and calendar |
| Report status | launch market |
A supplier who cannot fill the sheet in writing is not ready to quote. The same fields come back as the model page.
14. Design out the common failures
| Failure | Cause | Design response |
|---|---|---|
| Track that does not join | connector assumed from gauge | sample join test before order |
| Engine that fails under load | weak magnet or thin axle | pull test and loaded run |
| Set that does not fit its carton | packaging designed after the set | carton test with the sample |
| Report that does not cover the model | range claim instead of model list | model numbers on the report |
| Refill that cannot be sold | no refill in the range | anchor and refill specified together |
| Container that does not close | plan built on units | carton-based loading plan |
Each of these is cheaper to prevent at specification than to fix at the port.
15. What only the seller can answer
- Which models share the connector family, and which only share the gauge reference.
- Which fields on the specification sheet are final, and which move when packaging changes.
- Which models are stocked for reorder, and the typical reorder lead time for each.
- Which pack formats are available per model, and what each does to the carton.
- Which report exists for which model and market, and what has to be commissioned.
- What the loading plan looks like for the intended mix, and which constraint binds.
16. Sign-off checklist
- The brief fits on one page and no field is blank.
- The system decision is written, with the sample result attached.
- Anchor, refill and replacement are specified together.
- The sample was tested assembled, on carpet and under load.
- The carton record is confirmed per model and the loading plan checked.
- The report plan and model list are agreed for the launch markets.
- The reorder line and lead time are confirmed before the first order.
A range specified in this order can be quoted model by model, loaded carton by carton and reordered line by line. That is the difference between a catalogue of trains and a documented railway range.
