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.
Rapids not quite finished. but moving along, flowing off the front of the layout.
Moving on from two posts ago, working with the water
Adding more water layers

Adding more layers including highlights and foam

The next step was to airbrush the bridge with aged concrete.

Then test fitting the bridge in place

Then working out the river area under the bridge with aluminum angle, foam, plywood, masonite and caulk
Working out the river course
Then fleshed out a little more with rocks, sculptamold, and the start of scenery
River and banks starting to take shape
More scenery and bridge weathering in a future post.
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.

Pouring Hydrocal in a hurry – sets quick
and leveling off
Then back to the present starting the second pour
original cast and 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
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
Track down and stone wall further along with concrete cap.
Trying position of servicing structures
Working it out.
Camera and lighting set up after placing structures and ballast, greenery etc.

Just a few more examples of the things on view at Steamtown national historic site
Reading FP7 number 902
Massive UP Big Boy No. 4012
In an ongoing summer of visiting railroad related sites, we visited Steamtown national Historic site in Scranton PA. run by the national park service. A lot of very interesting trains and exhibits. I’ll post more in a future post, but thought this cool cutaway of a steam engine showing the firebox, Boiler, smokebox and cylinder, was a good introduction.

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.
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
UP in the mountains
Finally ending up in downtown Seattle including the docks.
Visited the Museum of Science + Industry, Chicago this past weekend, to see their terrific HO model railroad exhibit, from Chicago through the plains, the rocky mountains, and ending up in Seattle.
I will put shots of the exhibit up in future posts, but this one to one scale Empire State Express greets you at the beginning.

Another area that I am working on, both for operation reasons and for photography, is the yard and engine service area. Still have some final pieces to add to the concrete coaling tower, as well as definite weathering. This is the first of several structures to be completed for that area as well as track and signaling
Almost completed coaling tower
Also working on Sanding tower, water tower and stanchions, small sheds, as well as the switches and trackwork.
