The inspiration for my concrete arch bridge

Walnut Lane bridge over the Wissahickon creek

The Walnut lane bridge was certainly most of my wanting to reproduce something similar in HO scale. Although the Walnut lane bridge is a roadway bridge with cantilevered sidewalks, the main structural elements for a railroad bridge would be similar, and I did not try to reproduce an exact copy this bridge, which is right in my neighborhood.

The bridge was built in 1908 and at that time was the longest masonry arch span in the world, just now finishing a restoration.

Back, finally,  to casting the second side of my arch bridge, so to bring things up to date, here are a few shots of the mold and initial pour.

and leveling off

Then back to the present starting the second pour

Both casts with spacer cut from 3/4 inch Sintra (expanded closed cell PVC sheet)

I’ll continue detailing and assembly in the next post

 

Continue working on the Yard & Engine Servicing area

Some Photos showing progress, and also trying arrangements of structures for the engine servicing facility, and how these would photograph in different light (time of day-or weather)

Working with laying track and stone wall at one yard lead

Pretty interesting article in the New York Times about a new Model railroad Museum to be designed by Architect Frank Gehry

The Extreme Model Railroad and Contemporary Architecture museum in North Adams Mass. 83,000 square feet with 40 foot ceilings to accommodate 35 foot tall Empire State Building.

More about The Museum of Science and Industry in Chicago

The Museum of Science and Industry has a model train display that is really much more than just a train layout. It is about transportation, and how the railroads move goods from place to place.
The fact that it is beautifully crafted, with scale large sections of Chicago and Seattle and the industries , plains, mountains etc in between, makes it a modelers must see if you are in Chicago.

Chicago

The buildings in Chicago are true to the sections of the city that is being modeled. Two times an hour there is a short night segment to show the display in that setting.

Of course along the way showing double stack containers, mountain bridges and peaks, not to mention some human interest in a stream

Finally ending up in downtown Seattle including the docks.
