Z Gauge – Miniature Model Trains
Toy manufacturers can either invent something new or re-invent something old. One German toy company chose the latter option and gave us Z gauge.
Small Enough For You?
Märklin is a renowned German toy manufacturer whose name has become synonymous with model trains. It was a little surprising then that they did not get on the N scale bandwagon when it was introduced in 1962.
By 1968, with many manufacturers producing N scale trains, the question still remained… where is Märklin? That question would be answered in 1972 when they introduced their first Z gauge trains.
Gauge is the distance between the two rails of a track. In the case of Z gauge this distance is only 6.5mm (roughly ¼ of an inch) which is 1/220 the size of a real life standard gauge railroad track.
The Z scale model trains they produced were built to the same 1:220 proportion as their track making this the tiniest mass produced model train available. (T scale, at 1:450 is smaller but not as readily available.) So how small are they? This photo should give you a hint.
The letter Z was chosen because it was the last letter in the alphabet and at the time it was thought that no train could ever be smaller. They also coined the term Mini-Club to identify accessories for this new scale.
Pros and Cons of Z
So why would you want to model in Z gauge? Well the primary reason is that it’s a great space saver. Check out a typical HO layout on a sheet of plywood that measures 8’x4’. You can build the identical layout using the same number of trains, scenery, buildings, etc. in a space that’s only 3.2’x1.6’. In fact they are often referred to as coffee table layouts due to their compact size.
Naturally the small size also allows you to build a massive, sprawling and intricate layout with multiple lines of track which will accommodate locomotives hauling dozen of cars. In addition the scaling will be more realistic as you can put more distance between your industrial areas, villages and mountains so everything is not as cramped.
Another plus is that on an overall basis the quality of these trains is superior to those found in larger scales. This is because all these models must be manufactured precisely and to high standards or else they simply won’t run. There are no inferior “starter” trains.
One of the downsides is that the track has to be kept clean at all times as even the smallest specs of dirt or dust can cause operational problems. Then there is the pulling capacity of these small lightweight locomotives. It can be a challenge for them to pull a number of train cars up a grade that’s greater than 2%.
Also, even though Z scale has been around for almost 40 years other scales are still more popular. This means you won’t have the same variety of options in accessories or rolling stock that the modelers of more popular scales enjoy.
Although Märklin was the first to produce Z gauge, today there are many manufacturers worldwide and that number is growing. This allows anyone to model in virtually any era of their choosing.
