The essentials
- In railway modelling as with scale models, the scale, the make and the manufacturer’s reference identify a model.
- The original box, the instructions and the condition count towards the value of a collector’s model.
- A photographed inventory is useful for insurance, resale and passing the layout on.
Miniature trains and scale models: what to keep track of
A collection of miniature trains grows quickly: a locomotive, then a set of carriages, then the wagons of the same period, the scenery and the accessories. After a few years, you no longer quite know what you own, what is in the boxes in the attic and what runs on the layout. The same goes for model cars, model aircraft and ships, and dioramas.
Keeping the inventory of a model railway collection means noting, for each model, what distinguishes it from another almost identical one: the manufacturer’s reference, the scale, the period depicted, the motorisation, the livery, the presence of the box. It also means tracking what changes: a decoder added, a part replaced, a model lent for an exhibition.
What a model or miniature train entry contains
| Field | What it is for |
|---|---|
| Scale (HO, N, O, Z, 1:18, 1:43, 1:72…) | Sort models and compare what is comparable. |
| Make and manufacturer’s reference | Identify the model precisely and find comparable sales. |
| Prototype and period | Know which real machine is represented; put together consistent trainsets. |
| Motorisation (none, analogue, digital DCC) | Know what can run on which layout; track modifications. |
| Original box | An important criterion of value for a collector’s model. |
| Dimensions, weight, condition | Complete the identification; spot wear or breakage. |
| Photos and documents | Model, markings, box, instructions, invoices: the evidence in the event of theft or a claim. |
Sub-categories separate miniature trains, model cars, model aircraft, model ships and dioramas. Antique toys have their own page: antique toys and figures.
Value and insurance
The value of a scale model depends on its rarity, its condition, its box and its instructions. Note the purchase price and keep the invoice: it is the first proof of what you own. For the most sought-after pieces, keep the history of dated valuations rather than a single figure.
A collection set up in a dedicated room can represent a considerable sum without the insurer knowing. Check the limit set for collectables in your home insurance policy. Our guide to making a home inventory for insurance explains what evidence to gather before a claim.
Succession and inheritance
A dismantled layout and dozens of unlabelled boxes leave heirs helpless: they know neither what has value nor which club or specialist to approach. An up-to-date inventory, with your wishes for each set and the contact details of people who know the collection, saves them from selling everything off cheaply. Our estate inventory template can serve as a basis; for how it is treated in an estate, consult your notary (notaire).
Photos from your phone and sharing
Photograph each model in profile against a neutral background, then the markings, the underside, the box and the instructions. To have a lot valued or to offer it to a buyer, share a selection through a password-protected, time-limited link. If you already keep a list in a spreadsheet, our comparison Excel spreadsheet or collection software will help you choose.
With Collectalia
