There are several things to bear in mind when estimating a Hornby train.

The oldest models are in lithographed sheet metal, These are the most sought-after trains.

The trains manufactured at the start of production are in HO size, which is often the size most quoted at auction. The first trains are the BB 16000, the 131 Vapeur and the blue and silver 060 diesel.

To identify your model, you should also rely on the color used. Some trains may have evolved or been repainted. The original colors are of course the most sought-after.

Several checks are required. First of all, you should check that the landing gear is working properly, that no parts are missing or broken, and that no repairs have been carried out. During this check-up, don't hesitate to review the train's many functions. Does it run smoothly? Do the various parts fit together perfectly? Is the lighting, if any, on the cars and locomotive in good condition?

When the toy runs on electricity, the condition of the connectors and the device for the power supply should also be checked.

General appearance or aesthetic condition

Also examine the model carefully for any damage, such as scratches or dents. Check the paintwork on the locomotive and all other accessories for signs of wear. If the miniature is in poor condition, or if parts of the toy are missing or damaged, repairs or replacement of parts may be necessary. Restoration entails additional expenses and will logically affect the estimated price.

Some references are more popular than others. For example, Hornby trains marked LMS, an acronym for London, Midland and Scottish Railway, are generally very popular. There are many other models favored by collectors and model railroad enthusiasts, such as the miniature 131 TB steam locomotive, one of the last to be used in France, or the BB 1600, a former SNCF electric locomotive. The market value of a popular train, which arouses interest and admiration, is greater.

Hornby usually produces sets containing a range of accessories, including twelve curved rails, in addition to the locomotive. Note that curved rails have only one radius of curvature at first, then a second, larger radius. This can help you date your set. If you own this kind of set, make sure all the parts are present with your steam locomotive or electric train.

A range of elements may accompany these miniatures depending on the model.

From the passenger car, to the dining car, via the coal car, the freight car, the switching devices and the hopper : the presence or absence of one or more accessories can vary the market value of a Hornby train set.

The rarest Hornby trains are of great interest to collectors and model railway enthusiasts. They are the subject of successful auctions, with bidding prices in excess of a thousand euros. The more common models of these model trains are usually sold for a few hundred euros:
