Saturday, July 12, 2025 - Model Railroad Layout Tour

Layout Tour: We are very fortunate to have Ron Walker showcase his HO scale point-to-point Sonoma Valley and Napa Valley Railroad for the San Diego Division. His model railroad has been built specifically for Operation Sessions.

This will be one model railroad layout tour we recommend not to miss because Ron is in the middle of making his layout and we will see a model railroad that is in progress of being built. This layout tour will be an inspiration to all of us including those of us who are in the middle of making a model railroad layouts or to those of us who have not started one. 

• Date: Saturday, July 12, 2025.
  
• Time: Noon to 3 p.m.
• Location: The location will we provided to San Diego Division members on Thursday before the model railroad layout tour.
• Accessible: Not accessible.
• Masks: Not required.
• Carpooling: Help take the sting out of high gas prices and carpool with a friend.
• About Ron: Ron had a HO scale train set has a youth but never continued in the hobby as a young adult. He came back into the model railroad hobby sometime in the years of 1996-1997. Ron regained his interest in the hobby from joining the Poway Station model railroad club. He was introduced to many scales through his club, such as N scale, HO scale, O scale, G scale and 1-1/2 scale. (Note: 1-1/2 scale are the model trains that you ride on. For 1-1/2 scale, the distance between the rails is 7-1/2 inches).
• When he joined the Poway Station club, it was originally an all scale club. Poway Station today is now only an HO scale club. Personally, Ron's always modeled HO scale trains for himself. Then when DCC was becoming more known to modelers and the manufacturers, his interest peaked again in the hobby due to his extensive work experience in electronics.
• Ron started his own model railroad benchwork around 2000 with five modules. He started to build the remainder of his layout in his garage in 2020. The benchwork and track work in his garage is now complete. He is still in the process of finishing his model railroad layout.
• He is still part of the Poway Station railroad club.

More About the San Diego Division
The San Diego Division holds in-person meetings every second Saturday of the month, which include members showcasing their own modeling work, layout tours, and modeling clinics. (A clinic is where one of our members demonstrates techniques or skills needed for modeling, for example, an electronics clinic, how to solder, how to weather rolling stock, understanding decoders, or techniques to improve rolling stock standards.) We have quarterly meetings (which includes a luncheon), an annual swap meet, annual picnic and other activities for our members. The Division newsletter, "The Mail Hook", is published quarterly by email and is sent to our Division members.

The San Diego Division (California, USA) includes the Southern California counties of Imperial and San Diego with a population of over three million, and is one of four divisions in the Pacific Southwest Region (PSR) of the National Model Railroad Association (NMRA). The other Pacific Southwest Region Divisions are the Arizona Division, Cajon Division and the Los Angeles Division. Please find links to the National Model Railroad Association membership rates on our website.

Model railroading is also quite active in San Diego County, with multiple model railroad clubs (including the four clubs at the San Diego Model Railroad Museum in Balboa Park), there are many home layouts (of which a number of have active regular operating sessions), a very active Garden Railway Society, three model train stores, and several other general hobby stores that have model railroading supplies.

About the National Model Railroad Association
The National Model Railroad Association, Inc., is a 501(c)(3) not for profit educational organization that advances the global scale model railroading community through education, advocacy, standards, and social interaction. The NMRA is a three-tiered organization. The National Organization is sub-divided into Regions (18 worldwide), and those Regions are in turn sub-divided into Divisions. It is at the Division level that interactions take place between an individual member and the entire NMRA organization.

What's in a Name? 
The National Model Railroad Association (NMRA) has named all the local NMRA groups, "Divisions". While it is tempting to call our NMRA group in San Diego, a model railroad club, or just the club, that terminology doesn't quite fit. The reason is, a model railroad club is where their organization has its own a permanent model train layout, usually in a rented or owned public business-type building. NMRA local Divisions usually do not own permanent layouts. National Model Railroad Association Divisions hold meetings and events throughout the year. The San Diego Division is a very active National Model Railroad Association Division and holds monthly meetings. It is our members who typically own their own private model railroad layouts. We hope this explains why the San Diego Division is referred to as a Division and not a model railroad club (or a club)! 

San Diego Division Model Railroader Members
Our members are very active in the model train hobby in San Diego. Some of our members belong to model train clubs, some have their own model railroads and some do both. There are three types of model railroaders in this scale train hobby. People who like to run model trains, model train modelers and model train collectors. Many model railroaders participate in all of these activities. There is a wide range of model train skill levels in the San Diego Division.

In addition, many of our members participate in Operations Sessions here in San Diego. Many of our members have their own Operations Sessions at their home model train layout and many participate in their club's Operations Sessions. Operations Sessions are when you operate your model train layout like a real railroad. Operations Sessions keeps the interest and fun in the model train hobby for your entire life. If you are looking to meet and be part of an organization with active and experienced model railroaders, the San Diego Division might be the right place for you to join.

Please note: The San Diego Division does not have a dedicated physical meeting place or office. Each month, we meet at various locations throughout San Diego County. With the exception of during a pandemic, we hold virtual meetings. All photos on our website credit: The San Diego Division, National Model Railroad Association.
