    Default ExactRail’s Johnstown America AutoFlood II Hopper is a Fine Model

    Author: dennis.kamper



    For those of us fond of modern era coal trains, the March 2019 release of the Johnstown America AutoFlood II Hopper by ExactRail is a welcome addition at a good price point.

    The list price is $29.99. The more you buy, the better the unit price from ExactRail. This car comes with a coal load and internal bracing pieces that modellers (who want to run these cars empty but have them look authentic) can install.

    Eight different paint schemes are available for the following road names: Burlington Northern Santa Fe (BNSF), CSX Transportation (CSXT), Union Electric (UCEX), Commonwealth Edison (KGLX) and NorRail (NRLX). With the exception of UCEX (now owned by the Ameren Corporation) Military Veteran and On Track for the Cure. Twelve to 24 road numbers are available for these cars.

    About the Prototype
    A fundamental part of railroading since the earliest days, the hopper car has evolved like every other part of the industry. While the basic shape still shows through, these aren’t the same cars they used to be -- even as recently as the 1950s! Improved materials, and the ever-present need to move more product more efficiently, has seen the steel “coal car” or hopper car of our childhood transform from 50-55 ton capacity (with two bays and four unloading doors) to 90 and 100-ton capacity cars (with five bays and five unloading doors) in the mid-1960s.

    Since railroad cars in interchange service can only last so long (1), railroads were shopping for replacements to these cars as they approached their forty-year point. As the weight of a steel car body added to the cost of moving the products, lighter, higher-capacity cars were in demand. Enter the introduction of aluminum cars. And a perfect example of this transformation is the AutoFlood II Hopper.

    Johnstown America, now known as FreightCar America, still lists this summary on their product line weblink: “AutoFlood II ™ is FreightCar America’s automatic discharge, five pocket hopper car. The AutoFlood II ™ is aerodynamically designed with smooth sides to reduce wind resistance and improve locomotive fuel conservation.” (2)

    Prototype nicely rendered
    If we are trying to capture a particular age or point in time, having the right model goes a long way towards making the model railroad “look right.” Certain milestones are obvious indicators of your modelled era; road names, roof walks, car lengths, and designs of the cars themselves. As the older styles of cars disappeared, newer versions replaced them, so we have to follow suit if we want to portray an appropriate era and this is what ExactRail accomplishes with this new tooling.

    While researching useful details (to compare the model to the prototype), I found the following listing for some of these hoppers on a Machinery Exchange website (machineryhotline.com):
    “1998 Autoflood II Coal Hopper Railcar, (246 Avail). Rapid Discharge, 4300 CF [Cubic Foot] Aluminum 286K GRL [Gross Rail Load], Rotary Dump, 16 Door R D [Rapid Discharge] Gates.(3)”

    The Model: A nice balance between detail and sturdiness
    The body style with a steel weight built into the centreline frame of the car is reminiscent of hopper cars in my fleet that date back to the late 1960s. The ExactRail team has done a great job in capturing the look of the prototype car in all of the details without making it too flimsy. There is a fine line between producing a model that is true to life and still sturdy enough to be handled and run.

    The end structures, ladders and door actuators don’t look grossly oversized (this can be a problem with models trying to adhere to prototype true to life features), but at the same time are reasonably sturdy (I have not TRIED to break anything yet!).

    High-quality lettering and markings
    Machinery Hotline included some great photos (below) of different aspects of the prototype car that I could compare to the model; externally, the general details match the example found online (not a CSX car reviewed here), and the quality of lettering and marking is very good, even when zoomed in to try and read the tiniest printing.

    Internal bracings
    Internally, the shape and lines of the inside of the car look pretty good. The internal bracings are kind of hidden in the packaging (under the plastic cradle). Once I found them, it took me about 4 minutes to install the bracings, which are realistic-looking and are held in using friction (no glue).












    It’s always nice to not have to use glue, which can be messy to work with and require lots of work. Technically, you can run the car with the coal load and the bracings, but I would not recommend this. When I tried to insert the coal load, which features slots in it just for this reason, I found myself forcing down the coal load and displace one of the bracings.

    Structurally the car is sound. It features CNC-machined 36" metal wheel sets.

    Operation
    Mechanically the car is as good as any other ExactRail car I have acquired.

    Body-mounted Couplers
    The single best feature in my opinion is the body-mounted Micro-Trains 1015 couplers! Having recently converted a number of covered hopper cars to body-mounted couplers, this is no small advantage.

    One drawback
    One downside -- the car is light. NMRA recommended weight for a car this length is 1.1 ounces. My example weighed 0.7 ounces, which is “about average” for a number of cars I have re-weighted over the past few weeks. Weight determines how well a car rides and whether or not it derails.



    If a car is too light, it can derail. So it is common to weight cars, typically by adding sinkers. In this case, I would have to add a 0.5 ounce (to make up the difference between actual car weight and recommended weight) sinker. However, there is no place to conceal these weights in an empty car. In real life, these cars are NOT always carrying coal; they do ride the rails empty. Here is a great article about adding weights to a model train: How Much Does a Train Wheel Weigh?

    Summary
    ExactRail has done very well with this model. Given the nature of the model they produced, it appears that weight has been compromised in favour of the clean lines inside the car.

    Footnotes
    (1) The Association of American Railroads' (AAR) Rule 88 originally allowed for a maximum 40-year car life, but grants an additional 10 years through Extended Service Status (EXS). Today, all cars operating in interchange service are 50-year cars, either because they were built on or after July 1, 1974, or received rebuilt status of EXS under Rule 88.

    I have a number of hoppers in my fleet and these look good. In my book appearance when empty trumps proper weight, because properly weighted cars go overweight when I fill them with coal. The fact that they come with MTL couplers is a big plus for me.

    Wondering if you can tell how much rocker these have. I send my cars up-ramp to a dumper and then back down on a kickback track. The ramps require a reasonable amount of rocker in the trucks. Rocker is where you can swivel them upslope and downslope to deal with vertical curves. For example, here is a vertical "inside" curve near the bottom of a kickback.

    In situations such as the above most hopper models prevent the trucks from rocking so much that the inside pairs of wheels do not touch the rail, causing instant derailment. Same with outside wheels on "outside" curves where the ramps are transitioning from uphill to level track.

    How much rocker wiggle room do these have?
