Bridge Upgrades

February 25, 2012

We are always looking for ways to improve our products.  This time we created some new truss work details to make our bridges #110 and #111 more realistic.  These are two of our more popular bridges but we still believed we could add more value to them.   The best part is that we are not changing the price!  We hope you like the improvements and we look forward to hear your opinion.

O Gauge Vertical Lift Bridge

January 17, 2012

One of the first projects of 2011 was the fabrication of an O gauge lift bridge for The Paradise & Pacific Railroad in McCormick Stillman Railroad Park, for their new O gauge layout display.  We also built an O  and G gauge over head train systems for the lobby area of the new model railroad building.

The McCormick-Stillman Railroad Park is located in the heart of Scottsdale, Arizona, the park is the most unique of it’s kind in the country.  There are two historically-accurate scale-model train rides, a growing collection of full-scale railroad engines and cars, an original Scottsdale 1930s machine shop with all its tools and three genuine Santa Fe Railroad depots.  One of McCormick- Stillman Railroad Park’s most delightful— and unusual—features is the group of dedicated model railroaders who are members of four clubs “in residence” at the Park.

The model train layouts (O, HO, and N), which are operated by independent clubs are now housed the park’s new model railroad building.

Below you can see pictures of the Vertical Lift bridge for the P&P Railroad, O gauge Club and pictures of the Overhead train systems. located at the lobby of the new model railroad building.

Curved and Arched Bridges

December 29, 2009

Ok … Lately we have been working on some very interesting projects.  This one is definitely on the top of that list.   We had our friend Howard from Atlanta come up to us with a challenge.  He is building a new layout in his basement it is a basic oval shaped layout  but the bridges that he wanted weren’t so simple… 

He wanted to have something like this bridge

Ok that is not very hard to do… but what happens when you want to have a bridge like that on a 180 degree curve at one  of the ends of the oval and  one 90 degrees on the other end?

The Bollman Bridge For “G Scale”

December 28, 2009

The Bollman bridge will be our new project this is a very interesting bridge in Maryland.  We are going to be making the G scale version of the this Bridge;  below you can read a bit about it.  Then I will add pictures of the process of making the replica.

The Bollman Truss Railroad Bridge at Savage, Maryland is the sole surviving example of a revolutionary design in the history of American bridge engineering. The 160 foot double-span truss bridge is one of the oldest standing iron railroad bridges in the United States. It was the first successful all-metal bridge design to be adopted and consistently used on a railroad. The type was named for its inventor, Wendel Bollman, a self-educated Baltimore engineer.

 

The bridge was built for an unknown location on the main line of the Baltimore and Ohio Railroad in 1852, and was moved to its present location, spanning the Little Patuxent River on the spur to the Savage Mill, in 1887. The bridge remained in service until the mill closed in 1947; switching crews used additional cars in order to avoid crossing the bridge with locomotives, and thus there was never a need for a more substantial structure.

The Bollman Bridge is a two-span through-truss, resting on granite abutments at each end and a granite pier in the middle of the river. The truss structure is a mixture of wrought and cast iron. The truss configuration is the design patented by Bollman as the “Bollman suspension truss” in 1852. Each span is 79.5 feet long, 25.5 feet wide and about 21 feet tall. The Bollman truss suspends the deck from a network of tension members, while the top chord resists compressive forces. The system is therefore referred to as a suspension truss.

The truss includes decorative elements, such as Doric styled vertical members. The cast iron end towers, which bear transfer the weight of the structure to the abutments and pier, are also detailed. A decorative and protective metal enclosure at the top of the towers was lost to vandalism, but was replaced during the restoration work. Metal strips at each portal read “W. BOLLMAN, PATENTEE”, “BALTIMORE, MD.”, “BUILT BY B&O R.R. CO.”, “1869” AND “RENEWED 1866”. Replicas of the original strips were installed during the restoration.

The bridge was brightly painted, using red oxide for the towers and the heavier compression members and an ivory color for the lighter tension members.

****

The first thing we did when we started the construction of our bridge was to replicate the decorative elements:  The Doric vertical members and the metal strips for the portals.

To make the metal strips, the front plates were drawn and then cut on a computerized plasma cutting table, then flat bar was attached around the plate to complete the front strip.

Once those two custom components of the bridge were made, we could move on to making each side of the bridge.

After we had two sides for the bridge we started to connect them.

The Finished G scale version is 11 feet – 4 inches long, 13″ tall and 14-1/2″ ID – 18″ OD.,  wide enough for double track.

 

The bridge will get powder coated and after it is installed it will be painted as the original, red with white accents.  It should be a nice bridge to look at.

The Construction of the Sciotoville Bridge.

August 10, 2009

 19 Jun 2009

Hello All,

 I have a new project.  I’m building “The Sciotoville Bridge”  Here is a bit of information about this bridge

The Sciotoville is a steel continuous truss bridge across the Ohio River between Limeville, Kentucky and Sciotoville, Ohio in the United States. Designed by Gustav Lindenthal, the bridge was constructed in 1916 by Chesapeake and Ohio Railway subsidiary Chesapeake and Ohio Northern Railway as part of a new route between Ashland, Kentucky and Columbus, Ohio

The bridge is continuous across two 775-foot long spans, and is considered an engineering marvel. It held the record for longest continuous truss span in the world from its opening until 1945.

Today the bridge is used by CSX Transportation, one of the seven major Class 1 railroads operating in North America.

Eaglewings Line of Bridges – How it all began

June 3, 2008

 

 

BRIDGES

Bridges were the first product that Dan created when he began this hobby and joined a garden railroading club. He visited a few layouts and attended meetings to get ideas for his layout which is now the Wild Eagle Railroad. After seeing several layouts and reading tons of garden railroad magazines, he noticed that there weren’t any steel bridges, and since bridges are made out of steel, and he had a welding shop, it didn’t take long for him to start designing G scale bridges.

 At this point, they weren’t created for any business purpose; it was mainly to trade with other people in the club to get some help with things he didn’t know about. He started taking them to club meetings, and he designed them to see peoples’ reactions and hear their opinions. He got some good feedback, and was surprised when people asked to buy them right then and there. Dan didn’t even have an idea of what to charge for them at that point!
