Dick Bronson is co-owner and hardware designer for RR-CirKits, Inc. Model Railroading has been his hobby since he was a child in upstate New York. In 1998 he started a website offering "kits" of "circuit" boards that he had designed for his own model railroad, and called the site RR-CirKits. In 2003 He was offered the opportunity to build the original LocoBuffer, and by 2004 had redesigned it into a finished product, the LocoBuffer-II, and turned RR-CirKits into a full time business.

Dick and his wife Karen live in Waxhaw NC, the home of the only remaining wooden foot bridge over the CSX. Standing on the bridge while a train passes a few feet below you is the most exciting action in town.

Geoff Bunza started as a Model Railroader at age 6. His interest in modeling the New York Central was cemented when riding on a NYC fan trip to Harmon in 1966 behind S-Motor 110. He fed his interests through college becoming a member of the Tech Model Railroad Club (TMRC) at MIT while getting his doctorate in Electrical Engineering. He has given clinics throughout the US on scale model animation and written articles for Model Railroad Hobbyist, Railroad Model Craftsman, and the New York Central Historical Society Model Magazine. He is a life member of the NMRA and holds an Extra Class amateur radio license.

Dr. Bruce Chubb is a Master Model Railroader and the author of the model railroading books, How To Operate Your Model Railroad, The Computer/Model Railroad Interface (C/MRI) User's Manual and the two-volume Railroader's Application Handbook - a complete thesis on railroading applications. Bruce is a renowned author in Model Railroader and NMRA Magazine with over 60 articles to his credit. He is a major speaker at numerous NMRA national and regional conventions. Bruce, a retired electrical engineer in digital systems applied to aerospace, is currently occupied full time building and operating his Sunset Valley Oregon System to model ten prototype railroads operating in the Pacific Northwest. Additionally, Bruce is involved helping others incorporate the benefits of a computer interfaced to their model railroads via JLC Enterprises.

Mark Dance lives in Vancouver, B.C., with his "understanding and patient" wife Christiane and their two children. He has been an N scale modeler for 36 year. The Columbia & Western and it's operations have been described in a number of articles in the hobby press including Model Railroad Planning 2012. The C&W is also scheduled to appear in Great Model Railroads 2016. Mark has a degree in mechanical engineering (robotics) and spent 20 years as a product designer/inventor and manager.

Stuart A. Forsyth, a life member of NMRA, has been researching Cajon Pass (from Colton to Summit) since 1959. As Secretary and then Chairman of the Pacific Coast Chapter of the R&LHS, he helped create the California State Railroad Museum in Old Sacramento. He currently serves on the Archives Oversight Committee of the Santa Fe Railway Historical & Modeling Society's Western Archives, which are located at the Depot in San Bernardino. While his layout of Cajon Pass has yet to be built, he has learned a lot over the intervening years. Now that he has retired from his most-recent position as Executive Director of the Los Angeles County Bar Association, hopefully he will have time to turn dreams into reality in his large garage in San Diego.

Greg has been an active modeler in both N scale and HO since 1968. His layouts have been featured in Model Railroader, Model Railroading, N Scale Railroading, Great Model Railroads & Model Railroad Planning. He has also presented many clinics at various NMRA national conventions over the past 30 years.

Owner of Alkem Scale Models.

Modeling with the masters instructor.

I have loved trains since WWII days, watching the SP in the San Timoteo canyon. Yes I vaguely remember steam, mostly in helper service. I spent most of my adult life in passenger transportation - busses and now as a Conductor with Grand Canyon Railway. I model HO, HOn3 and 1:8 scale, 7.5" gauge.

Prototype modeling columnist for Model Railroad Hobbyist.

Mick Moignard has been modeling D&RGW and RGS prototypes in HOn3 since the mid 70's and with DCC since 2000. Mick considers DCC and onboard sound to be the greatest thing for the hobby since we abandoned keys for electricity.

Dr. Muff has been collecting brass model railroad equipment and modeling in HO scale for over 50 years. He has a large home layout with a focus on passenger railroading from the late 1940's to the mid 1950's. The center piece of the model railroad is a scale recreation of Kansas City Union Station and downtown Kansas City. The stage for the model railroad is set by a full scale F-7 locomotive cab and a ACF passenger car mock-up. He enjoys CAD drawing and over one hundred of his articles and plans have been published. He is a member of the National Model Railroad Association and several historical societies. For twelve years he has been involved in research, drawing and production of fine-scale HO brass models of steam and diesel locomotives and passenger equipment of the Mid-west. He is a Radiation Oncologist practicing in the Washington State.

His Grandfather had the honor of driving the "Royal Train" from Field to Revelstoke,
B.C. in 1939 with The King & Queen of England onboard during their royal tour of
North America.



Don joined Pacific Western Rail Systems / North American Railcar in 2006. NARCorp
manufactures HO & N scale rail cars with attention to accuracy and detail. NARCorp
is producing the protypically correct National Steel Car 3400 CuFt Potash hopper
for the NMRA 2015 convention car.

Mat Thompson grew up in Oregon. He now lives in Gainesville, Va. His HO scale Oregon Coast Railroad was featured in Great Model Railroads 2014. With a nearly finished layout, his present hobby efforts go into hosting and attending operating sessions.

Owner of Fast Tracks, manufacturer of precision turnout construction jigs.

Greg Wright has been modelling since 1975 in HO, HOn3 and 1:32 scale. His current railroad,
the Consolidated Republic Mining Railroad, is built in 1:32 scale in a 22' by 14' space,
smaller than many HO scale layouts. Greg's layout has been featured in Railroad Model Craftsman,
Finescale (Outdoor) Railroader and numerous times in the Narrow Gauge and Shortline Gazette.
Greg received MMR #520 in the fall of 2013.
