Collecting Crude Oil On Your Layout You may have read stories about oil wells and spec- tacular gushers at a new oil strike, but once the well is opened up and the excite- ment has died down, oil pumps keep crude oil flowing to collection tanks. Walthers chose one of the most common styles of oil pumps, the walking beam design as made by Lufkin, as the basis for its Cornerstone Series ® Oil Pumps, HO Scale 933- 3170 $24.98, and N Scale 933-3248 $21.98. On the prototypes, an electric motor or diesel engine drives a counterweighted crank that moves one end of a steel beam up and down. A pulley sector is connected to cables reach- ing into the well; the sector is the familiar “horse head” shape we associate with these pumps. Each kit includes one pump, chain- link fencing, decals and a base with a below-surface motor mount. Because pumps come in many variations and sizes, Walthers designers pat- terned the model on sever- al versions to yield a “typi- cal” pump. These kits are designed to accept Motorizing Kit, 933-1050 $19.98, because many modelers like adding ani- mation to their model rail- roads. The realistic motion these pumps add to your pike will be well worth the effort. Creating a realistic oil field on your pike is easy. Oil fields are usually spread over several miles, you’ll rarely see a single pump in an area; most are connect- ed to centralized collection tanks by underground pip- ing. Just place the Oil Pumps in small flat spots in your trackside farm fields or in fenced-off areas in your cities. Oil pumps come in many sizes with heights ranging anywhere from about 6- to over 20-feet; well depth determines what size is used. HO Scalers can use the N Scale models on their layouts to represent smaller pumps; just leave off the fencing. If you want to add a stand of collection tanks, place the tanks from the Interstate Fuel & Oil kit, HO Scale 933-3006 $25.98, N Scale 933-3200 $21.98, on end and add the kit’s truck loading rack. If you model the transition- to classic diesel-era, place the tanks and loading boom along a siding.

Collecting Crude OilOn Your LayoutYou may have read storiesabout oil wells and spec-tacular gushers at a new oilstrike, but once the well isopened up and the excite-ment has died down, oilpumps keep crude oilflowing to collection tanks.

Walthers chose one of themost common styles of oilpumps, the walking beamdesign as made by Lufkin,as the basis for itsCornerstone Series® OilPumps, HO Scale 933-3170 $24.98, and N Scale933-3248 $21.98. On theprototypes, an electricmotor or diesel enginedrives a counterweighted

From Sludge to SuperOnce crude oil enters therefinery piping, it’ll neverbe the same. The oil isheated in the fractionatingtower, breaking it downinto its components, orfractions. These settle atdifferent levels within thetower as illustrated in theaccompanying diagram.The compounds are drawnoff and sent for furtherprocessing and storage.

United Petroleum Refiningis based on a small refin-ery which handles distilla-tion. Hundreds of thesesmaller facilities couldonce be found across thecontinent. The prototypesfor the Walthers modelwere chosen because theycould be used on transi-tion- and modern-era lay-outs without using up toomuch space. In recent

years, these smallerprocessing opera-

tions have beeneither mod-

ernized andexpanded, or

closed. A few, how-ever, are still operated

by independent producers.

At many modern refiner-ies, heavier compounds gothrough additional process-ing into gasoline and otherlighter, higher-value com-ponents. Further chemicalprocesses bring productsup to desired specifica-tions; many of these addi-tives arrive by rail. Theseprocesses make regulargasoline different frompremium, for example.

Bring the look of raw

industrial power to yourlayout by placing United atthe heart of your refiningscene and surrounding itwith piping and a tankfarm. Real refinery struc-tures are usually servedonly by maintenanceroads; tank farms areserved by truck roads andrailroad sidings.

The towers and struc-ture began life as the oldNorth Island Refinery kit.Walthers revamped the kitwith new thin-profile walk-ways, caged ladders andetched-metal handrails togive catwalks and towers arealistic, superdetailedappearance.

Refined Oil On The MoveAs you might imagine,refinery tank farms handlea wide variety of products.Tanks are seemingly scat-tered all over the country-side; roads twist their wayaround and over earthen orasphalt berms. The entirearea is blanketed by a webof elevated, ground-leveland underground pipingwhich connects fractionat-ing towers, processingfacilities, storage tanks,long-distance pipeline ter-minals and loading racksfor trucks and tank cars.Gases have their ownpipeline system betweenthe refinery, storage tanksand loading facilities.

While in the past mostrefined products moved byrail, today, most gasolineand other high-volumeproducts move to regionaldistributors’ tank farms bypipeline. Other productsand byproducts, such asasphalt, lubricants and fueloils move by rail, truck,

pipeline and, in somecases, tanker ship, to usersor distributors. Propaneand other gases move viapipeline or by rail inLiquefied Petroleum Gastank cars.

Tank Farms, The MostVisible Part of YourRefinery SceneTo make your refineryscene complete, surround itwith a tank farm. Incomingcrude oil and refined oilproducts are stored here.even though these facilitiescan be quite large, they’reeasy to add.

Each tank is surroundedwith an asphalt or dirtretention berm which con-tains the tank contents incase of a rupture. The areaaround the base of the tankis usually gravel, sometimeswith a few weeds poking upthrough the rocks. Tanksare usually numbered foreasy identification, andthose visible from publicroads often wear the com-pany logo. Roads andpipelines follow the gridlaid out for the tanks.

The Walthers Wide OilStorage Tank kit, 933-3167$29.98, and the Tall OilStorage Tank kit, 933-3168$29.98, feature CornerstoneSeries® 500,000-Gallon and575,000-Gallon tank bodieswith all-new details.Walthers revamped thesekits for easier assembly andgreater detail. The new kitsinclude modular retentionberms, form-fitting stair-ways, berm crossover walk-ways and realistic decals.

Rail and truck loadingfacilities are also part ofthe tank farm scene. Justadd the Oil LoadingPlatform, 933-3104$11.98, along the spurserving your tank farm andthe new Truck LoadingRack, 933-3169 $24.98,along the main road lead-ing into the tank farm.Connect your loadingfacilities to the rest of thetank farm by either under-ground or above-groundpipelines and weather theimmediate areas with a bitof oily black paint, oil pas-tels or chalks. Don’t over-do it, as modern loadingfacilities are kept prettyclean for safety’s sake.

Aggregates Rock Your WorldQuarries feed rock productsto businesses everywhere.Limestone, one of the mostwidely quarried minerals, isused in an amazing varietyof manufactured productsincluding steel, cement,plastics and pharmaceuti-cals. It’s also an ideal mate-rial for construction andrailroad ballast because itsrough surfaces lock inplace as it settles.Aggregates account for alarge percentage of railroadfreight traffic.

In This Corner: The CrusherAfter a quarry blast, heavy-duty front-end loaders scoopblasted stone chunks intohuge Terex dump trucks fora trip to a conveyor dumphopper. From there, convey-ors carry it up to the crusheron the surface.

The crusher breaks downthe rock, screens it to spec-ification and, depending onits size and use, loads itdirectly into hopper cars,dump trucks or onto anoth-er conveyor for stockpil-ing. At some locations, it isalso fed into pulverizers

which reduce it to a finepowder for specialty use.

Crushed Stone On Your LayoutAt many quarries, perma-nent rock crushers handlethe final loading intoaggregate cars, ballast hop-pers and trucks. Waltherspatterned Glacier GravelCo., HO Scale 933-3062$39.98, N Scale 933-3241$39.98, after a versatilefacility with two loadingspots in the tunnels andone on the side, all of

which can handle hoppercars or trucks. Its corrugat-ed construction makes itusable on transition- andmodern-era layouts.

Byplacing the rock face of thepit wall on the front edgeof your layout, you cancreate a scene that makesyour layout look larger.Use rock molds such asthose made by WoodlandScenics or Color-Rite toconstruct a realistic pitwall.

Run conveyors from thetruck dump at the pit bot-tom up to the crusher.Depending on your pitdepth, you might needextra conveyor sections;matching conveyor sec-tions and supports areavailable as Walthers partnumber 933-3149, $8.98.

Quarries and rock crushersare usually covered withdust; check out the prototypephotos for weathering ideas.To recreate this look, add alight dusting of chalks or alight gray spray from an air-brush. Roads can be darkerto simulate the passing of awater truck for dust control.Add even more character toyour scene with a few ruststreaks on the metal build-ings. Bottom-dump aggre-gate trucks, such as thosemade by Trucks N Stuff andBoley, make great additionsto your crusher scene.

It All Begins With A Big BangThe sound of wailing sirens fill the air, then, an eerie silence, and BOOM! You can feel the shock wave pass throughyour body. Huge billows of dust spread out over the area and settle in a fine, powdery layer. When the dust clears, therace is on to get the rock properly crushed, graded and on its way to industrial users. This is where the fun begins!

This crusher receives rock from another crusher in thepit (just visible above the trucks in the foreground) andreduces it for truck loading. Notice the gray coating oneverything; the water truck in the foreground has sprayedthe roadways for dust control. Walthers Archives

Think About HowMuch Pavement You See Every DayAccording to the AsphaltInstitute, the United Statesalone has over 2,112,000miles of roads and high-ways surfaced with asphaltpavement. Add to thisparking lots and pedestrianwalkways, and that’s a lotof blacktop!

While most people callhighway blacktop “asphalt,”asphalt is actually theheavy oil, a commonbyproduct of oil refining,which binds aggregatestogether to make the pave-ment we’re used to drivingon. Hot-mix plants com-bine heated liquid asphaltand crushed stone in arotating kiln. Open dumptrucks haul the hot mixtureto the paving site where it’srolled flat and left to cooland harden.

Hot-Mix Plants GiveYour Railroad A HotMix of TrafficHot-mix asphalt plants arecommonly found in indus-trial districts along railroadlines. Walthers decided toproduce its HO Scale BlackGold Asphalt kit, 933-3085$79.98, as a natural addi-tion to its group of aggre-gate industries. It’s basedon a typical facility whichreceives rock and asphaltby rail or truck. They comein many sizes; many arelocated adjacent to quarriesand some are portable.

By detailing and weather-ing the scene surroundingyour hot-mix plant, it’seasy to create a realisticindustry which can enhanceyour train operations.

The asphalt piping, truckloading area and roadsleading into it are usuallystreaked with oil. Take alook at the prototype photofor ideas on weathering.

Since many modelerswant to add special effectsto their models, Walthersdesigners left enough roomin the kit to add the SeutheSmoke Generator 667-117,sold separately.

Hot-mix plants commonlyreceive asphalt 23,000-Gallon Funnel-Flow TankCars. The cars in asphaltservice look the same as

standard cars, but are fittedwith interior heating coils.Crushed stone arrives inOrtner 40' AggregateHoppers, such as thosemade by Walthers, or otherbottom-dump hoppers.

Have YouEverWonderedHow MuchYourLocomotivesCan Pull?On real railroads, locomo-tive purchases, powerassignments and tonnageratings (recommended ton-nage per unit) are all basedon the information gatheredfrom testing with adynamometer car.

Dramatic changes in rail-road technology early inthe 20th century madedesign evaluation critical.Freight cars were gettinglarger

and more efficient steamlocomotives were needed.Dynamometer cars carrieda large dynamometer, adevice used to measuremechanical force such asdrawbar pull, and record-ing equipment to gatherlocomotive performancedata. The cars also provid-ed sleeping quarters fortechnicians.

Coupleddirectlybehind the loco,dynamometer carscould be seen on solo testruns or with freight or pas-senger trains trailing them.

While dynamometer carsfirst appeared in the late1800s, cars similar to theWalthers Dynamometer Carhit the rails during the1920s. As the railroadsdieselized, the cars weremodified to test diesel loco-motive performance.Because they weren’t usedon a daily basis, they typi-cally had long lives; manylasted well into the 1980s.

Here’s How You CanTest Your HOLocomotivesThe WalthersDynamometer Car workslike the prototype; couple

it between your locomotiveand train and it’ll measureyour approximate drawbar

pull. The car can pullup to about

8 ounces

ofdrawbarpull; each markon the data readout,visible through the car’ssliding doors, is approxi-mately one ounce. Thelines are unmarkedbecause no two springs areidentical. To calibrate yourcar’s dial, temporarilyattach a one-ounce weightto the car’s testing couplerusing a string, leaving theweight free to drag alongthe rails. Pull the car untilthe object just begins tomove. This is the point atwhich the car is pullingone ounce. Adjust the dial

as outlined on the includedinstruction sheet.

Armed with your test data,you can make comparisonsamong your locomotives.Prototype railroads havedone this for decades, now

you can, too.

The WalthersDynamometer Car Looks Good, TooYou can also run theDynamometer Car as arealistic piece of workequipment. Just couple itbetween your locomotivesand train. As a scenic addi-tion, you can place it inyour railroad’s shop sceneor on a siding at a passen-ger depot.
