"Often one plans and builds something
that later shows itself to be less interesting or of less value than originally anticipated.
Occasionally the reverse is true: the product proves better than hoped for."

(John Allen, Model Railroader, November 1972)

 

 

My Z Scale layout is entirely the result of "trial and error" and a long journey of "back and forth".

 

 

Much of what has materialized in the end happened to do so because my initial idea didn't work at all or simply because I changed my mind.

At times it was like seeing only a hazy shade of a distant train in the fog, other times it felt like pushing on with a fast freight through a snowstorm wipeout.

 

 

But it all came together in the end - the result of "accidental modelling".

 
 

THE LURE OF THE CONTINUOUS RUN

 
Something that separated real trains from model trains since the latter's inception was the direction their travels would take them in. In the real world, trains would travel from A to B, whereas model trains generally just ran around in circles.
 
  No matter the scale, the brand or the style, "starter sets" have come with either a circle or an oval of track for decades.

As boys playing with toys evolved into serious modellers, the starter set's oval of track was recognised as being very far removed from actual train operations, subsequently frowned upon, and finally given the derogatory labels "toy set" or "tail chaser".

 
In an attempt to elevate it far above and away from the toy train set, the term "continuous running" was coined, and serious modellers built some serious layouts which strived to camouflage as best as possible the fact that trains ran in circles. The companies making model train starter sets also tried to improve the perception of the basic oval, by adding double and triple track running as well as more and more complex yards and sidings - all provided for, step by step, through "expansion packs" of track to this day.

Individual railway modellers came up with more prototypical linear layouts very early on in the hobby's history (such as A. R. Walkley in the mid-1920s or Cyril J. Freezer in the 1950s), but the happy memory of watching trains pass by (albeit in a repetitive circle) persisted in many railway modellers.

 

 
  The lure of continuous running is at least partly rooted in its resemblance to what a person standing trackside in the real world sees: a train approaches from one side, runs by, and then disappears to the other side of the onlooker's position. Even though it happens over and over again on an oval of track, the passing train essentially recreates this scene. It also allows for a very relaxed experience - with the controller set to a fixed speed, the assembled model train will simply loop around the track without any further handling needed.

However, one of the major problems with continuous run layouts is the space required to accomodate them.

 
They are space hungry because they have to accomodate semi-circles of track; in the most popular modelling scale of HO/OO, even using the fairly tight so-called 2nd radius curves requires a minimum board width of at least 100cm (40 inches) - although this will give very little room outside the track for e.g. scenery, so actually a baseboard width of 120cm (48 inches) is called for.

Having (too) many hobbies that all require space has put me in a position of lacking an exclusively designated, permanent "model railway space" for most of the time. And whilst this introduced me to "shelf layouts" and "shunting puzzles", the lure and pull of the continuous run layout with its trainspotting perspective always remained, and strongly so.

 
 
 

Z SCALE: DESKTOP RAILROADING

 
Lack of space has always been one of the main reasons for the development of smaller model railway scales (such as the introduction of TT (1:120/1:130) in 1945, and N (1:148/1:160) in 1962), but at a scale ratio of 1:220, Z Scale offers the possibility of running trains in a confined amount of space which simply would not be possible in other modelling scales.
 
  In promoting Z Scale, Märklin thus always emphasized the smallness of the models; besides choosing the last letter of the alphabet to designate the scale, they also used the moniker "mini-club".Initial advertisements also made certain to point out the advantages in comparison to the traditional space (and skill) requirements of larger modelling scales.

"Nothing like it has ever existed before. Never before has reality been presented in such fascinatingly small size and exciting detail (...) Mini-club will conjure up a wonder world on your table, all in full view, which you can reach from your armchair. No basement is required, no suite of rooms and you do not have to be a do-it-yourself fan either. The mini-club is a true leisure time hit and makes an exciting hobby into a portable leisure time game."

 
Micro-Trains, on the other hand, sold their US Z Scale train sets back in the 1980s and 1990s as "desktop railroading". Either way, modellers had to be introduced to Z Scale, and starter sets for continuous running on a circle of track were the traditional and proven ticket.

Märklin, 1986

 
The initial starter sets from Märklin and Micro-Trains (containing Märklin track) came with track ovals measuring only 51x44 cm (21x17 inches), and those small round-and-round layouts became something of a calling card for Z Scale, with some of them even finding sufficient space within the confines of a briefcase.
 

 

As the years progressed, some of Märklin's starter sets grew to to include more track and turnouts (and in some cases even two trains), but for obvious reasons they always stuck with the formula of the continuous run oval of track.

I initially saw Z Scale as nothing more than a gimmick; putting together a briefcase layout seemed like the obvious (and only) thing to do in order to see the models run.

 

 
However, once I actually got to run a few Märklin and Micro-Trains models in the early 1990s, I started to view Z Scale as a potentially serious modelling scale. I was sold on desktop railroading, but there had to be more to it than just a simple circle of track.
 
 

LOOP TO LAYOUT TO NO LAYOUT

 
The logical progression from the basic (starter pack) loop of track is to build something a bit more complex and interesting. Several "shake the box" ready-to-run options are available, ranging from Märklin's track extension packs to preformed scenicked layout bases (some even contained in the (in)famous briefcase). They provide modellers with layouts that could be compared to painting pictures "by numbers": they are built following reasonably straightforward instructions, but the end result will be a layout that is replicated by hundreds of other modellers with very little room for individual touches.
 
 

A step up from this is to take some inspiration from a trackplan someone else has designed or even a layout someone else has actually built. A very early Z Scale example of the latter is the Pennsylvania & Pacific, a layout that featured prominently in the April 1985 issue of Model Railroader.

It was accompanied by an in-depth portrait of (then still fairly new) Z Scale and packed a lot of model railroading and inspirational allure into a mere 2'x3' (60x90cm). But the transition from loop to layout can be fraught with risks and tripwires.

 
 
Setting out to build a straightforward clone of the Pennsylvania & Pacific with regards to the track plan (a figure eigth folded back onto itself), I decided to add my individual touch to the layout by leaving out most of the hidden track along with the scenic divider running down the middle of the layout - which proved to be a huge mistake. Whilst the layout was fun to build, simplifying the scenic contours seriously diminished the visuals and resulted in a somewhat disappointingly uninteresting layout.
 
It was a classic false start that completely derailed my interest in Z Scale for a while. Linear shelf-size layouts in N and eventually HO/OO scale were fun to build and operate - but they didn't offer the delights of continuous running.

I therefore dipped back in and out of Z Scale once every few years, but none of the approaches (modular or small single baseboard layouts) were able to rerail things. It almost seemed like Z Scale just wasn't right for me - until I came across David K. Smith's James River Branch layout and website by chance in late 2011.

 
 
I was completely mesmerized not only by his superb modelling efforts but also by the approach (you might even say philosophy) to modelling in Z Scale that he formulated (which also happened to include the assertion that false starts are, quite simply, part of the modelling process). His layout was small and a simple single track affair, measuring a mere 15"x36" (38x92 cm), but it was massively inspirational. I also got almost everything wrong about it all, and it sent me on a decades-long back-and-forth journey from one layout project to the next - none of which really worked out. And it took me an embarrassingly long time to realise why.
 
 

KEEPING IT REALISTIC

 
The first potential tripping point is linked to the fact that whilst Z Scale is small, this doesn't mean that everything undertaken in this modelling scale will automatically be small too.
 
  I had far too often ignored the reality that my limited amount of model railway space not only meant that a layout (or parts thereof) would need to be portable, easy to handle, and easy to set up - storage space requirements would have to be a consideration too.

The problem with my layout projects wasn't so much the space it took to set it all up temporarily, but rather the space that was required to store it properly when not in use. The perception of base units of length seems to differ quite a bit during different stages of layout planning and building at times, but of course they are always the same. I needed to take the approach originally advocated by Märklin and Micro-Trains seriously - think small, build small, and enjoy desktop railroading.

 
The second tripwire I kept stumbling across was that Z Scale somehow generated an enthusiasm that had me cutting corners and rushing into far too many layout projects.

It happens with other scales too, and it happens a lot, to a good many modellers. It can be fun, too, but it inevitably leads to far too many abandoned layout builds and far too few hours spent actually running trains. Going back and forth between single baseboards and modular layouts that ultimately didn't work made me realize that I needed to stay in the modeller's armchair way longer and think things over more than twice. It's good to have a clear list of requirements (what you would like to see in a layout), but it is essential to acknowledge the list of restrictions (what you can realistically do and what you simply cannot).

In the end it's rather easy: planning outside the box of the physical restraints of a given reality is fun but will not produce a layout that actually works. Only keeping things real will, and in my case that meant keeping it small.
