Seth Neumann is a retired electronics industry professional with 30 years of experience in the computer and communications industry based in Silicon Valley.
Seth is a modern-era modeler whose home layout features the Union Pacific in the San Francisco Bay Area in 1999. He is an avid operator and hosts regular op session on his “UP Oakland Subdivision” as well as being a regular operator at many Bay Area layouts and attending visiting ops meets around the US and Canada.
Seth specializes in communications systems for model railroads, having developed telephone systems for many operating layouts and having presented clinics on the subject at many model railroad meets, including NMRA regional and national conventions. He also designs power distribution, DCC, signaling and other electronic controls for model railroads. Seth, along with Chris Drome, has implemented Radio Frequency Identification (RFID) on his layout to generate switchlists. Seth and the late Chuck Catania founded “Model Railroad Control Systems” which is an open source clearing house for Arduino based model railroad applications including Arduino based C/MRI modules compatible with Bruce Chubb’s C/MRI system.
Seth is a founding Director of both the Operations Special Interest Group (SIG) and the Layout Design SIG and Past President and President Emeritus of LDSIG. Seth holds NMRA achievement certificates as Electrical Engineer, Chief Dispatcher, Model Railroad Author and Association Volunteer. Seth also belongs to the Santa Fe Railway Modeling and Historical Society, the Southern Pacific Historical and Technical Society, the Union Pacific Historical Society and the Western Pacific Historical Society. He has written articles or presented clinics on the following topics:
- DCC for Dummies (1995-1997) with Ed Loizeaux
- MoPac Roofing Granules Hopper (1997) (in the MOPAC Historical Society)

Chuck was a transition era modeler with strong family ties to the Southern Pacific Coast Division. Chuck enjoyed applying prototypically authentic operating rules and practices to model railroad layouts. His own Chittenden, Pajaro and Coyote depicted the Southern Pacific between Watsonville and San Jose and uses C/MRI with full ABS/CTC signaling in compliance with the prototype in that era.
Chuck was the principal designer of the cpNode system. Working with Dr. Bruce Chubb, MMR, Chuck wrote the draft for CMRInet for submission to the NMRA as User Group Specification LCS-9.10.
Intimately familiar with DCC command systems and various software development environments on both Apple and PC platforms, Chuck created a wide variety of solutions to specific client requests while working on consulting engagements. He designed and implemented many signaling and layout control systems using JMRI on multiple OS platforms and digital command systems.
Chuck presented clinics on practical signaling of model railroads using Arduino at regional and national meets and enjoyed the challenge of studying and learning new signaling systems. Pre-1950 North American railroad signaling equipment, practices, and rules were a particular interest and focus.
Chuck was a long time member of the Southern Pacific Historical and Technical Society and was the project manager in charge of the restoration of the Southern Pacific interlocking tower at Santa Clara.
Chuck passed away in January of 2019, and we miss him!
