The Union Pacific was built as the eastern portion of the Transcontinental Railroad. The original line was built west from Omaha across Nebraska and Wyoming, into Utah to a meeting with the Central Pacific at Promontory. Within a few years the junction was moved east to Ogden. In the early 1900s, the mainline of the Los Angeles and Salt Lake, an UP subsidiary, joined the original Overland Route at Ogden. The majority of UP’s traffic went through Ogden.
Ogden to Pocatello, Idaho and from Granger, Wyoming to McCammon, Idaho, but they were not used on those lines. Because Cheyenne was their home shop for heavy work, the Big Boys regularly ran from Ogden to Cheyenne for shopping. When released from the shop, it was customary to use the Big Boy as a helper for Sherman Hill for a few runs before releasing it back to the freight pool. Before long, the run from Ogden to Cheyenne was the normal Big Boy operating area.
Model Features The Genesis™ 4-8-8-4 Big Boy is the culmination of the art of design and tooling integrating the latest innovations in electronic technology. The Big Boy model has been developed from its inception as the finest three dimensional operating miniature representation of the prototype available. Enclosed in the premium quality box are the following items: 1. History and Instruction Book that includes a warranty and instruction card 2. HO scale 4-8-8-4 Big Boy Locomotive 3.
Sound and DCC Features DCC Features: The installation of sound in a locomotive adds a new dimension to operation. Sound makes a technically perfect static model come alive and enhances the experience of operation. You will find that you will no longer "run" the engine but, rather, operate it in the context of your layout. Whether you are using conventional DC control or a DCC system, the incorporation of advanced electronic technology will provide the ultimate railroading experience.
Your new GenesisTM Big Boy Locomotive comes factory equipped with a state-of-the-art Dual Function decoder. This means your locomotive will run on any NMRA compatible DCC system or on any regular DC Train Control (HO power pack). Caution: Do not run your new GenesisTM Big Boy Locomotive with power packs intended for “G” scale [do not exceed 18 V DC] as you may damage the locomotive circuitry.
1. Place the locomotive on track 2. Turn the power switch on the power pack to ON 3. Slowly turn the throttle until the idle sounds come on. Once the idle sounds steady out, leave the throttle as is, and turn the power pack’s power switch to off. 4. Enter the program mode by pressing and holding the Stop Button [STP] while you turn the power switch back on. When the locomotive says “Program,” quickly release the stop button.
5. If the top voltage setting at maximum speed is too low, use the power pack's throttle to adjust the top voltage setting. 6. To conserve battery life, use the throttle to control locomotive speed and use the transmitter to activate sounds. 7. When finished running your locomotive, turn your powerpack throttle to OFF and turn off the power pack’s power switch. Any programming changes made in DC analog mode will affect any prior DCC mode settings.
CV29 for a 2 digit address, or a value of “34” in CV29 for a 4 digit address. 3. Locomotive idles but does not move or respond to functions. Make sure you did not program the locomotive into an advanced consist, [CV #19]. In your DCC system’s “Program CV Mode”, input a value of “0” into CV #19. 4. Any misguided programming of values in the DCC mode can cause a decoder to malfunction. Always try to first set the decoder back to it’s factory defaults by using CV #125.
chaser at their discretion. If it is decided that smoke units will be installed, carefully follow the installation and operating instructions provided by the smoke unit manufacturer. Genesis does not warranty any defects in these smoke units or damage that may occur to the locomotive through their use. Installation is very easily accomplished: Slide the smoke unit down the smoke stack until it engages the electric contacts inside the boiler.
