Very Large Scale Traction & Trolley Models


 

A CONTROVERSIAL SERIES BY Hal Pelta
 
Let me start by saying that the Reader will have to take full responsibility for any conflicts and hostilities that may break out in Traction Modeling as a result of this article. I’m presenting a very personal slant because, although I’m very peaceable myself and tend to avoid contention, confrontation, and sturm und drang , I like to challenge people’s preconceptions. So-o-o ..... here’s an idea that you may consider controversial … or creative and challenging ! 

With very few exceptions, the term “Large scale” as currently used in trolley modeling refers to the scales clustered around one-half-inch-to-the-foot (1 : 24) --- so-called G Gauge, LGB size or Garden Railway.

 
CAN WE USE THE TERM "DisplayScale" WITHOUT INCURRING THE WRATH OF MATTEL ?

For traction modelers looking for something different, we will consider the truly Very Large Scale : two inches to the foot, or (1:6). The Mattel Corporation (Barbie et alia) has labeled 1:6 scale as PlayScale, and has undoubtedly copyrighted that term and registered it as a trademark. Therefore, for purposes of this discussion, let’s call it DisplayScale. That name says a great deal about this concept, because of the many ways it lends itself to dioramas and displays. DisPlayScale (1:6) is the primary subject of this discussion  

DIORAMAS and REALISTIC SCENES

There is an entire sub-culture (another very descriptive and underutilized term) that devotes itself to building dioramas ---- elaborate depictions of real life situations,  representations of a particular place, frozen in time, to portray a scene that almost cannot be distinguished from a three-dimensional photograph.

AROUND AND AROUND

Let’s consider a typical traction layout : track laid out into a small series of curves that frequently (almost inevitably in the United States) curve back on themselves in the topological equivalent of a circle, so that the model trolley repetitively circles the same pattern of track over and over, a characteristic ensuring sleep after the third or fourth circuit . 

I suppose that no one has ever questioned that paradigm since the first track placed around a Christmas tree by Joshua Lionel Cowan, founder of Lionel . I understand that he persuaded department store managers and window dressers (once an esteemed profession) to place these track circles around Christmas trees in their display windows and run them continually ... the motion attracted attention from passing pedestrian shoppers, which is exactly what both Lionel and the department store wanted . Folks stood gaping outside in the snow, watching the train go around . Unfortunately, the idea became too closely entangled with model trains, and most American layouts today are designed using some variation of that paradigm .

HANDS-ON CONTROL

In earlier times, the electronics required for the necessary remote control of locomotives had not yet reached the degree of technical sophistication and capability that they have today. Therefore, back then, hands-on control of speed, direction, and sound by an onboard engineer was necessary. This set the theme for all riding scale locomotives for, it was thought, all eternity.

     IT'S IMPOSSIBLE TO RIDE A TROLLEY LAYOUT WITH OVERHEAD WIRE

Building and running trolley models meant straddling the roof and destroying the trolley poles or pantographs, ripping up the catenary as you went. We did not say prevented; we have seen  spectacular models of trolleys in 1½ inch scale (e.g., by Bruce G. Moffat), but they are outdoor and few in number .

REALISM IS DESTROYED

Spectators’ expectations have increased dramatically over the past 30 to 40 years. The audience has become increasingly sophisticated, and wants to view a realistic scene (“viewscape”) with everything to scale. Seeing a giant human being (the engineer or operator) astride a model or riding on a tiny trailing car destroys the illusion for most people. With the introduction of computer games, the necessary willingness to suspend disbelief has diminished greatly.

 TOM SWIFT & HIS REMOTE CONTROL TROLLEY

As we heard in reports from Iraq and Afghanistan, the wars in the Mideast have been conducted using Unmanned Aerial Vehicles operated by personnel hundreds or thousands of miles away.  I advocate fully electric unmanned motive power, modeled primarily on electric prototypes --- trolleys, box cabs, transit, and light rail, heavy traction, etc. --- featuring the very highly developed electronic control systems that are now available.

        NEW & RARELY CONSIDERED SUBJECTS

In this series of articles, we will be examining such subjects as

         I . Watch ‘em; don’t ride ‘em;

         II. Accurate street scenes;

         III. If Barbie and her World War II friends can                 do it, why can’t we?

         IV. Realistic passengers

         V. Repetitive routes, or ‘round and ‘round: 

         VI. Forced Perspective : The closer, the larger;  the farther, the smaller !

         VII. Benchwork : The Jimmy Sparkman Approach --- eight, weight, and slotted aluminum construction     

         VIII. The use of backdrops;  AND

         IX.   “What scale do I model in? Why, all of them !!”. The  Magic of Modeling in multiple scales.
