Neumann, Seth


Seth is a retired electronics industry professional. His home layout features the Union
Pacific in the San Francisco Bay Area's Niles Canyon in 1999 where he hosts regular op sessions. Seth specializes in communications systems for model railroads. He's developed telephone systems for several operating layouts and presented numerous clinics on the subject. He also designs power distribution, DCC, signaling and other electronic controls for model railroads.

Clinics Presented:

CMRI 30th birthday celebration

2015 Marks the 30th anniversary of the C/MRI system as described by Dr Bruce Chubb. This is a get-together with presentations by Dr. Chubb and some of the manufacturers supporting C/MRI and the proposed S-9.10 CMRInet standard.

In addition to the presentations there will be an opportunity for C/MRI users to introduce themselves and describe their layouts and projects.

Day Time Room
Thursday, Aug 27 7:00 PM to 9:30 PM Mt. Bachelor

Designing a signaling system with cpNode (CMRI on Arduino)

Chuck and Seth will describe their experiences designing and implementing Model Railroad Signaling Systems and how they have used the cpNode system they developed, to streamline the process.
They will discuss power distribution and detection topologies, setting up signal locations, dividing the layout into blocks, cabling, cost optimization strategies and much more.

Day Time Room
Thursday, Aug 27 9:30 AM to 10:30 AM Three Sisters
Saturday, Aug 29 8:00 AM to 9:00 AM Three Sisters

LDSIG boot camp

An intensive 4-hour session on track planning sponsored by the Layout Design SIG. Discover how to refine vision, concept and purpose; select layout footprints and schematics; draw accurate and useful plans; create efficient and engaging yards and industrial areas; make best use of staging tracks; maintain space for people; and avoid common track planning errors.

Day Time Room
Monday, Aug 24 8:00 AM to 12:00 PM Mt. Bachelor

LDSIG panel: What would you do differently?


I will moderate a panel of 4 or 5 local layout owners, SIG Tour hosts, and pose a series of topics about lessons learned about design, construction and operation. We usually record this so we can share the transcript in the LDJ.

Day Time Room
Thursday, Aug 27 10:00 PM to 11:00 PM Mt. Bachelor

Phones for Ops - updated!


Seth Neumann will review the requirements for an operations communications system and take you through the design process and show you how to implement a reliable telephone system for dispatching any era from the 1870s through the 1980s using your choice of inexpensive telephones or period equipment. The emphasis this year is on low cost electronic replacements for hard-to-find vintage parts.

Day Time Room
