For Sale: Prices reduced on Keller Engineering Onboard Locomotive Sound & Control System and components purchased directly from the late Bob Keller in 1982-91 as a fellow manufacturer (Brass Car Sides).
The system was in service and well-maintained on my large HO layout and was removed in working condition in 2007.
