Preserving History  The WDHS was formed to preserve the history of the Union Pacific Railroad’s Wyoming Division from Cheyenne, Wyoming to Ogden, Utah from the original building of it as part of the Trans-continental Railroad of the 1860’s up until 1957.  The target year of 1957 was chosen to include the final steam giants on the road, Big Boys, Challengers, 4-12-2 9000’s, FEF 4-8-4’s; and the early Diesels, F units, E Units, PA’s, GP-7’s and GP-9’s, and the unique Gas Electric Turbines.    The history of interest is not only the locomotives and the rolling stock, but also buildings and the scenery.  The operations of the UP in 1957 are of special interest to the Society.  In that era passenger trains were still important as well as freight trains over the highest pass of the original Transcontinental Route, Sherman Hill west of Cheyenne (8,013 feet) and the equally steep and very long grade of the Wasatch Mountains in Utah.  These steep grades made a natural bottleneck for all traffic east and west, because this was by far the most busy route for east-west traffic whether located in the north or the south of the US.  The history is preserved by both modeling this area in HO on a giant dedicated 50 x 75 foot building in Arizona, and by regular operating sessions that run passenger and freight trains using the procedures and rules of the UP in 1957.  The operating sessions are manned by 4 permanent docents for the HO layout and by up to 40 volunteer “operators” who are modelers from across the nation.  These guest operators fill jobs for Dispatchers, Trainmasters, Yardmasters, Classification Foremen, Hostlers, Road Crews, and Road Switching Crews in 4 to 7 hour long sessions.	  The Layout  In addition to the 485 mile double and triple track main line between Cheyenne and Ogden, the HO layout includes Several UP Branch Lines as shown in large type on this Timetable Map of the Division.
The HO layout has approximately 1,006 feet on each main line for a total of over 2,000 feet, or over 33 scale miles.  Counting the 168 foot hidden track on the OSL branch line and all the yards and sidings, there is a total of about 5,300 feet of HO track on the layout. The layout is built using a standalone mushroom design on two levels plus the third hidden layer level for the OSL.  A mushroom design allows foot traffic of both sides of all benches, so all welded steel framed free standing benches have two levels (plus the hidden third layer).  All of the upper level benches are accessed by operators and visitors from a riser built over the concrete floor of the building.  The lower level benches are reached from the concrete floor.  You can see that the green track of the lower level is accessible directly from the double front building doors, and the upper level must be reached by walking around the next to the last bench on the right from those doors and up the two steps to get onto the riser.  This complicated arrangement uses a lot of space (no benches are up against walls), but it nearly doubles the bench space (and room for track).  The big advantage is that visitors and operators are always looking north across any bench, which makes the tracks to the left appear to be going west, and those to the right seem to be going east.  So it is a very natural feeling design, especially if you have any familiarity with Wyoming and Utah.  Another big advantage is realism; anyone on either level cannot see anyone in an aisle except those to his left (west) or to his right (east), so it is like being on the tracks out on the prairie. Operations According to History Operations are all important to the Historical Society and to the layout, because it was built specifically as a “layout for operations.”  Operations in model railroading has a special meaning.  It is not just running trains for the enjoyment of seeing beautiful models in motion.  It is running trains with a purpose, as if the operators were a full railroad industrial company trying to make a profit by delivering freight and passengers for customers in a timely manner.  This means each load or passenger on each car has a specific unique destination as if the freight was requested to be moved there by customer freight agents, or because each passenger bought tickets to go a certain place at a certain time.  It definitely is not just running around the Christmas tree, as can be seen by the extensive list of jobs in the third paragraph of this section. The above italicized definition of operations is further complicated by the effort to make operations on the Wyoming Division HO Layout prototypical, that is, as realistic as compared to the real UP in 1957 as possible.  It could be argued that this makes operations and the track plan simpler, because of the high fidelity to those of the Union Pacific.)  To be specific the HO layout operating system simulates that of the Union Pacific in 1957 which used Rule 251D with Written Track Warrants as a traffic control method.  On the east side of Sherman Hill this was supplemented by ABS (Automatic Block Signals).  (Aren’t you glad you asked?)  What this boils down to is that to safely operate a train (the overriding reason for the rule book), a Written Track Warrant is required as authority to move a train on a single track in a single direction.  The “D” refers to adopting the rule for double track, and written authority is still required but each track is for one designated direction (usually double tracks use right hand running, but not always).  The ABS supplements the written authority in that trains run in order according to the signals unless a train is ordered by the Dispatcher to move to, or stay on, a siding or yard track to allow another train (one that is superior) to pass. This means the Dispatcher has to know at all times approximately where each train is, to make sure he can issue an order to be given to a train crew to “go in the hole” (take a siding or stay in a yard) until a superior train can pass.  That way the most superior trains (passenger trains, followed by Pacific Fruit express [PFE] and stock [cattle, sheep, hogs], and priority freights, and then the lowly drag freights and locals get to pass less superior trains.  The Dispatcher keeps current on the positions of all trains via a 16 phone system from the layout floor or riser to the Dispatcher (DS).  Road Crews report to the DS via the phones (or Tower Operators report for the road crews, as was actually done on real railroads).  The Tower Operators or road crews report train number (loco number), type of train (passenger, local, Manifest, Forwarder, or Special), direction of travel, and location. The passenger trains needing to be run to deliver people per a schedule is an obvious need.  But how does a railroad, especially one in 1957 without computers and few radios—certainly not in each cab—manage to move freight efficiently enough to gain and keep customers?  Real railroads used waybills generated by freight orders by customers to railroad freight agents, who shuffle the papers to make the freight go the right place on time.  The waybills were carried by the conductor in the caboose.  On the model, we simplify this process somewhat, but retain the flavor of prototypical freight orders and car forwarding.  Each model car has a car card or several cars may be considered to be a unit together as a block as if they were one “car,” and that block will have a card.  Either way the car or block cards specify the present location (“from”) and a destination (“to”), and whether the car starts and ends as full or empty (MT)—similar to a waybill.  The cards stay with the cars (in a pocket on the front fascia of the bench) or with the road crew on their clipboard, a standard office clipboard (as in the caboose).  When a car (with its card) arrives at a destination, it is set out by the crew and new-to-the-train cars are picked up to be taken with the train as it leaves.  This way cars or loads or blocks of cars arrive at their final destinations from any originating location on the layout. Operating Sessions So an operating session is a fast paced 3D real time “video game” with many players (up to 40), with passenger trains passing all other trains if necessary while they wait for them to pass, other superior trains passing others, and passengers boarding or stepping off the passenger trains at each depot along the route, and freight being picked up at any loading dock in any yard, town, or country and other freight cars being set out anywhere, all under the control of the Dispatcher who gives orders to the Tower Operators who pass them on to the Yardmasters and road crews, and the Classification Foremen and Hostlers take directions from the yardmasters to make sure the setouts and pickups get done correctly, and the locomotives are changed according to the grade ahead and the load being hauled.  Oh, and the locomotives have to take on diesel fuel every half day or so, but the steam engines need coal and water about every 50 miles!  That is, whenever the Locomotive Card says to stop for those commodities.  And we try to do it like the real railroad did it in 1957 without radios or computers.  Our limited paperwork is real paper (cards).  It is easy to see why it is such a fun and rewarding hobby, and how historically interesting it is, especially for youngsters.  Youngsters and Ladies Speaking of kids, there is no reason for us older modelers to lament the lack of youngsters in the hobby.  See the article I wrote for the AZ Division of the National Model Railroad Association (NMRA) KIDS AND LADIES ON AND ABOUT THE WYOMING DIVISION Or Don’t Tell Me There Ain’t No Kids or Ladies in Model Railroading       It is reprinted in the “Articles” section.
