Series: Old Time
Subject: 2-6-0 Steam Locomotive
Roadname: Denver & Rio Grande Western
Roundhouse/Model Die Casting (MDC) and Athearn are now under one management. You might see "Athearn" as the brandname when they mean "Roundhouse", or vice versa, so also check Athearn. And the steam locos now being produced are a generational step above what they were before.
2-6-0 "Mogul" Type Locomotives
The first North American example of this type of locomotive was built for the Louisiana & Nashville Railroad
[sic] in 1864. At the time it was the largest locomotive and got its name from the Mohammedan Empire (India). More than 11,000 Moguls were built between 1860 and 1910. They were generally used on freight trains but had enough speed to occasionally pull a light passenger train. 
Denver & Rio Grande Western 2-6-0 "Mogul"
Denver & Rio Grande Western Railroad took delivery of 22 class 805/G-20 Moguls from Baldwin Locomotive Works between October 1890, and May 1891; most were scrapped before 1920. Two were converted into 2-6-0T tank locomotives, one in 1928. In the 19-teens several were renumbered into the 500-series.
To heft tonnage across the mountains D&RGW 2-6-0s had small drivers of 46” diameter. Their 50-ton Moguls had the following technical statistics:
• Boiler Pressure, 140 psi
• Cylinders (dia x stroke), 18" x 24"
• Tractive Effort, 20116 lbs.
• Factor of Adhesion, 4.23
Roundhouse HO RTR Old Time 2-6-0
Roundhouse released their 2-6-0 in the following roadnames: Baltimore & Ohio, Boston & Maine, Canadian National, Chesapeake & Ohio, Denver & Rio Grande Western, New York Central, Santa Fe, Southern Pacific, and undecorated.
Roundhouse advertises that the basic model will be detailed to represent an individual railroad with specific headlights, domes, pilot wheels, and smoke stacks.
The prototype that Roundhouse modeled their 2-6-0 from is indistinct. Roundhouse was part of Model Die Cast
. MDC produced the locomotive kits. According to the authoritative Rensselaer Railroad Heritage Website
Originally, MDC produced a boiler and cab superstructure based on Santa Fe practices…
ATSF Old Time Mogul 2-6-0 - A c. 1880's loco, with Baldwin characteristics. This model has the same 51 inch diameter drivers as their "Old Time" 2-8-0, but they also offered a version with the larger 62 or 63 inch drivers. This model is ready-to-run.
2-6-0 Mogul - It appears MDC took their new 4-4-0 and added another driver instead of the second lead truck. This model has much taller drivers, maybe 63 inches and I don't think it is the same as the above Mogul.
American 4-4-0 - MDC has a new state-of-the-art rtr 4-4-0… It appears to be a c. 1890's loco with arc or oil headlight, wood cab, ringed Baldwin-type domes (although there may be other varieties, square steam chest and inboard valve gear). If this is truly as good as it could be, this could revolutionize the hobby, allowing for more modelers to model earlier periods, and the one review I've read gave it a stellar rating. It appears MDC started with their "Old Time" boiler/cab superstructure.
The actual model dimensional data is:
• Overall length, 57’ 6” (60’ 6” coupler to coupler)
• Engine wheelbase, 24’
• Overall wheelbase, 50’
• Driver Diameter, 66”
• Weight, 10.8 oz.
HO RTR Old Time 2-6-0, D&RGW No. 592
Roundhouse released many 2-6-0 models with DCC and sound. Those were discontinued although the current offerings are equipped with Quick Plug DCC technology.
Roundhouse models are packaged in an olive box that displays the model through a cellophane window. The model is packed in a Styrofoam cradle with a fitted clear lid. A thin sheet protects the model from scuffing. Documentation includes an exploded-view parts diagram and parts list.
The locomotive and tender models are connected. You will have to disconnect the wiring harness and drawbar to separate them. The model is ready to run straight out of the box.
The locomotive and tender are fully assembled. This Mogul continues the tried and true Roundhouse model engineering concept. You have a diecast boiler and a styrene cab shell secured upon a die-cast underframe by screws. The tender is plastic. Mounted on the locomotive underframe is the dynamically balanced five pole skew wound motor with flywheel. This transmits power to the axles of each powered driver via worm gears. The only drawback is that the drive can be seen in the open space between the running gear and the boiler.
Power is transmitted from the track to the motor via the trucks of the tender. None of the drivers have traction tires. This model has a single connecting rod for all of the drivers. Prototype steam loco manufacturers found this to be flaw, and it does not work well on model steam locos, either. However, Roundhouse’s model does not mind and runs well. Attached to the rods is a representation of Stephenson valve gear.
The metal drivers have nickel tires. Unfortunately, the pilot truck wheels are shiny, as are the tender wheels.
The old MDC boilers had piping and appliances cast on. Not anymore. Most of the main details are plastic or light metal and separately applied. Few elements are molded on.
My inspection finds the model to be in conformance with NMRA Standards and Recommended Practices
, with RP-25 wheels and couplers at acceptable height.
• Fully assembled and ready for your layout
• Prototype specific smokestack, dome, headlight, lead truck and tender
• Upgraded drive mechanism
• Equipped with Quick Plug DCC technology
• Razor sharp painting and printing
• McHenry scale knuckle spring couplers installed
This sharp model features the type of detail that, until about a decade ago, was only found on brass imports.
On the Inspection Track: DetailsFirst, the engine
. The pedigree of the engine has been discussed. The headlights represent electric types. Each headlight has a single micro bulb. These give a bright white glow. They are directional.
We’ll start our walkaround at the front with what differentiates classes of steam locomotives from each other, the wheel configuration. A Mogul
is a 2-6-0 per the Whyte notation. The leading (pilot) truck features no detail. The wheels are shiny. Next are the six 66-inch drivers. Brake hangers properly detail the spaces between the rearmost drivers, though no driver springs or sand pipes are represented.
A detailed and animated Stepheson valve gear sprouts from the rear of the simple cylinder chest. Both plastic and metal parts make up the valve gear. It looks smooth when operating.
This is all set in and upon a metal frame. The firebox is festooned with rivets. The engineer side sports a feedwater pipe and reverse bar. The fireman side has the prominent air pump, air reservoirs, and feedwater pipe. No piping is attached to the reservoirs and no piping is present below the running boards.
This Mogul features a road pilot with a McHenry knuckle coupler. Above and behind it is the pilot deck (‘campground’ in hobo-speak) with metal tread decking. It lacks a train line and air brake hoses. The coupler cut bar and handles cross over this assembly.
The smokebox front is sharply detailed with a variety of molded and applied accessories. This model has a slight gap between the smokebox front plate and the smokebox body. The smokebox is painted graphite. No wires to the headlamp can be seen due to the tight fit of the headlight to the smokebox top. Individually applied marker lamps and handrails adorn this area. Atop the smokebox is a stack with overscale thick walls. The number plate rounds out the engine’s face. Brass paint simulates the plate edge.
The boiler is a sharply cast metal shell with separately applied steam and sand domes. No flash, ejector marks, sink holes nor seam lines are apparent. Surface detail includes recessed lines for the boiler sheathing, raised detail for the boiler bands and fasteners. Including the previously mentioned parts I identified 23 individual parts applied to the boiler:
• Pop-off valves
• Feedwater piping
• Railings and grabs
• Marker lights
• Air reservoirs
• Air pump
A separately applied cab brings up the rear of the superstructure. While it does not feature a folding deck between it and the tender, it does have individual grab irons and handles, and molded arm rests and sunshades.
The “interior” features a molded backhead with basic detail such as firebox door, gauges, and rivets. Neither the “hogger” nor fireman have seats due to the small tight fit. No crew is provided and there isn’t any room to put full figures in the cab anyway.
Second, the tender
. This is a typical tender of the era. Roundhouse molds it to accept a coal or oil load. This model represents a coal burner. The coal is not realistic looking. Aside from the rivet detail these tenders are fairly plain. The tender has scale ladders, steps, and hand rails. The chassis is not detailed. Like the engine pilot deck the rear of the tender sports no air or train lines.
Supporting all of this is a pair of four axle trucks. The wheels are shiny. The trucks have good side detail including eye bolts.
The decorated D&RGW locomotive features crisp, sharp opaque lettering on the tender and the cab sides. I cannot find any information whether Rio Grande
used this livery on the 2-6-0.
The paint is smooth and I noticed no blemishes. Brass boiler bands and domes are simulated with brass paint.
Mogul in Motion
While this is a great model for static display, how does she move? Steam loco models, on account of all of those rods and valve gearing, tend to be balkier than diesels. Though did not test-run this model, the previous 2-6-0s I reviewed ran very well straight out of the box across my track work of code 83 and 100 Atlas flex track and Atlas and Peco turnouts. To watch one of my Roundhouse Moguls in action visit HO RTR Old Time 2-6-0, C&O #425
To what standard do we judge this model? Steam locomotives were usually quite unique to the railroad that used them. Their appearance could vary considerably after a few major shoppings. One of the givens of steam locomotive modeling is that if you want a particular steam loco, you need references for that
locomotive, during a particular period of time. To be frank, that’s what brass models are for. This model is a standard design that Roundhouse tweaks with different stacks and headlights to be close enough for a 2-6-0 of a popular railroad. However, the drivers are way too large for the D&RGW prototype.
So how about it as a model? My other Roundhouse 2-6-0s ran well, with pulse they creeped as slow as you’d probably want. The non-pulse minimum speed was disappointing. Yet, the mechanism and drive were smooth and quite.
The decorating is fantastic. The separately applied detail parts are impressive.
Despite the much too large drivers, these generic models, so good right out of the box, do afford us the opportunity to model the era of the Industrial Revolution through the Golden Era, without spending your life savings on a brass model. They offer the opportunity to kitbash and detail to more closely model a specific engine. The price is good. I do recommend this model.
Athearn and Model Die Casting/Roundhouse are now under one management and you might see "Athearn" as the brandname when they mean "MDC", or vice versa, so also check Athearn. And the steam locos now being produced are a generational step above what they did before. [RMRRS]
