Starting to assemble parts for a large stone wall behind the town

Been coloring these Motrack stone wall castings made of Hydrocal.

Stack of stone wall castings

These are colored, or really stained with many layers of sprayed dilute india ink and dilute woodland scenics burnt umber scenery color. They will be put up end to end with concrete buttresses at the joints of the separate pieces. Actual length of wall about 44 inches long total

The Mammoth Amherst Railroad Society’s Railroad Show

Just returned from W. Springfield MA from the biggest model train show in the nation. Quite an experience. Over 400,000 square ft of dealers, manufacturers, modular layouts, etc.

Car in the parking lot right where I pulled in. No doubt I was in train land!

The show is in 4 buildings. this is the entrance to one of the four (Mallary Complex)

They also have some special things like this Real 1895 Baldwin steam engine, built for SD Warren Paper Co, that has been restored to full steam operation.

All in all , a very enjoyable weekend

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.

Completing my cast hydrocal Cement arch bridge

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.

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
