A weighty matter (or two)

The first weighty problem, and I really do mean weighty, concerns the stock for such a layout. Just take a look at this lovely Weaver GP38-2. It weighs a ton! Oh all right. I exaggerate. It weighs three and a half pounds (1.6 kilograms). That’s a lot. Especially when you’ve become used to 3D printed locomotive kits that only weigh a matter of ounces. 

3.5lbs of brute force

It does make one think about the design of the baseboard for this little cameo. If you review some of James Hilton’s videos on his YouTube channel concerning the construction of his cameo boxes. Those are all built from 6mm MDF with no framing. Rigidity is created by adding the sides and roof to the box. This creates a very lightweight structure where the model scene just seems to float on the shelves in his office. This lightweight method works well for the smaller scales like N and 009. But is unlikely to work in the senior scale. Where something more capable of taking the weight of the locomotives will be needed.
I can see no reason why 6mm MDF couldn’t be used as the baseboard surface. But a more traditional bracing method will be needed to be used to support it. That will need some more thought.
The second weighty matter is more metaphorical than physical. 
The main attraction of the Plymouth industrial park for me has always been the Coil Cars, and as it stands there’s no place for them on the layout. Other than as a bit part player to pass through the scene, and this is weighing on my mind. 
Could I replace the fiddle yard exit on the left with another warehouse? One that takes Coil Cars. The Olympic Steel warehouse is a huge structure. A mock up ensued to see what the effect of a large structure at the end of the layout would be…
Probably not…

The reverse curve into the warehouse would be problematic
The reverse curve needed to get the track into the door entry towards the rear of the baseboard just looks awkward, being able to see the overhang on the cars. On the previous version of the layout, I was obstructing some of this with the fiddle yard exit structure. 
I did like this arrangement
So, the solution lies somewhere between the two. Then a Micro Model Railway Dispatch reader reminded me of a scheme I had proposed for a small steel distributors micro layout back in the preview issue of The Dispatch. It still has an overgrown, unused siding in place as you can see from the Google Earth view. Who knows how much rail traffic it used to see?
Duluth Steel Distributors premises
We would seem to have a solution to the problem. 
Onwards we go.

  1. RE Loco Weight : 5mm foamcore as per the original ChicagO Fork is _still going strong_ despite handling a brass CLW GP38 (something like 4.4 pound) and both Atlas plastic, Red Caboose plastic kits, and Overland brass cars (up to 2.2 pound per car) as it's regular 3:2:2 Inglenook roster or equipment. The key is adequate design and manufacturing accuracy, of which you, Ian, have bucketloads of in-reserve! ;-)

  2. Indeed Prof. I have been re-reading your how to on foamcore baseboard construction. I'd like to be able to build something with a pelmet and a full frame.

  3. If it lives on a shelf when operating, and when you move it won’t have a loco on, why does it need to be anymore complicated then a pair of 6mm pieces laminated together for the base?
