ed and detailed with rocks and logs. Three separate pours were made to achieve the desired re- sults, which includes falls and rapids. There are 12 tunnels and 15 bridges on the railroad, including a non-working bascule lift bridge. One of the highlights of the layout is the number of highly detailed scenes, many of which tell unique and amusing stories. For example, one river scene includes a canoe, but the cano- ers are in the river with their paddles, and a black bear occu- pies the canoe. There is a hobo camp complete with a flickering fire burning in a 50-gallon drum and a girl on a picnic outing chasing a couple of skunks. As a bit of whimsy, several dinosaurs have been hidden in the scen- ery for the younger visitors to find. The dinosaurs are periodi- cally moved just in case a young visitor has a repeat visit to the Museum.


Electrical From the start, the layout was designed for DCC and con- trolled by Dr. Bruce Chubb’s C/ MRI (Computer Model Railroad Interface) and NCE wireless controls. There are 124 signals on the railroad, including 18 double-headed and two triple- headed signals (62 are CTC/ dispatcher controlled and 62 are intermediate signals), and 20 CTC-controlled turnouts or crossovers. Another 16 turn- outs are electrically locked or unlocked by the dispatcher for local control by the train crews performing switching chores. All switch machines are slow- motion Tortoise controlled by proprietary circuit boards. There are 201 JCL Enterpris- es DCCOD detection circuits for signals and CTC operation, as well as 14 SMINI’s (Super Mini-Node Interface) cards and three SUSIC motherboards that control 17 I/O cards. One NCE command station and 18


NCE 5-amp boosters installed around the layout run the DCC NCE system.


Besides systems that control the railroad, three SMINI cards control the roadway operations in Klamath Falls and logging trucks above the town of Sycan. The roadway system is a modi- fied German Faller system using an embedded wire in the roads and self-propelled vehicles that follow the wire using a magnet attached to the front axle. The


programming even sets up cars and trucks to stop and go at var- ious traffic lights located in the city of Klamath Falls.


The railroad can be operat- ed in the dispatcher-controlled CTC mode, manual ABS (abso- lute block signals), or automat- ic “docent” computer mode. In the CTC dispatcher-controlled mode, the dispatcher operates a replica of a prototype 1970s- era Union Switch & Signal CTC panel that was built using parts


“EELT”


GP40 7213 leads a three- unit OC&E consist down- grade over Bridge 13 spanning Deep Creek with the eastbound “East End Log Turn” (EELT). Its 30 loads of lumber load- ed in skeleton log cars are headed for process- ing at the Fremont Saw- mill in Lakeview.
