Scale Trains Crude Oil Tank Car Review Comparison of the Rivet Counter Operator Series


End detail comparison between the Operator version (left) and the Rivet Counter version (right). 


Okay, time to get back to something more relevant to my primary focus for this blog (well, in theory anyhow) – model railroading.

Tonight I thought I’d take a look at some of the differences between the Scale Trains Operator and Rivet Counter lines which offer differing levels of detail for their “crude oil tank car” model.

The Prototype

The advent of easy to reach light sweet crude oil in the Bakken formation extending over much of the United States and Canadian prairies spurned a boom in the need to move this oil to refineries. Whereas pipelines offer greater capacity, they are stubbornly fixed in place, while railcars can be routed anywhere on the North American rail network. This is particularly beneficial to refineries beyond the reach of pipelines, such as those near the Pacific or Atlantic coasts (many pipelines tend to run generally north-south). 

While some of this demand could be met by existing equipment, new tankcars were required to handle this boom in oil traffic. Light crude is less dense than some other bulk liquid commodities so capacity could be expanded to just over 31,000 US gallons (30,000 gallons was the previous standard size). An industry-lead move to enhance tankcar safety resulted in the so-called CPC-1232 standard, whose key features over a standard 111A100W1 tankcar include: half-height head shields, fittings protection (in the event of a rollover), and increased tank thickness (9/16” vs previous minimum 7/16”). One builder of this new standard of car is Trinity Industries (the prototype Scale Trains modeled), which produced thousands of CPC-1232’s to meet the oil boom demand.

The Model

As noted previously, two versions of the car are offered: a basic model (“Operator” line) and a more detailed version (“Rivet Counter” line). I could tell you that “the model closely matches prototype dimensions”, but this isn’t Model Railroader. Instead, this post aims to identify some (not all) differences, and comment on the execution of each model. For this review, I acquire one of each version of the car, DPRX 259272 (Operator Line, Deep Rock Refining), and TILX 350417 (Rivet Counter Line, Trinity Industries Leasing fleet).

Side-by-side comparison of the two boxes for the Operator and Rivet Counter lines. It's easy enough to tell the difference from the front, but a difference of colours would make it even easier to tell the two lines apart.


            Operator Version

I think the concept of the Operator line is a brilliant move on Scale Trains’ part, especially for a car such as the crude oil model, which like the prototype is likely to operate in unit train consists. This appeals to someone wishing to run an HO version unit train, which would probably be prohibitively expensive to do with a solid train of Tangent-like quality. The Operator line comes with the same basic details including handrails metal wheels, side ladders, wire handrail stanchions, and most of the graphics. What it lacks compared to the Rivet Counter version includes:
  • Coupler operating levers
  • Double-shelf couplers
  • Rotating roller bearing caps
  • Wire grab irons
  • Placard decals
  • Mesh running boards
  • Thicker head shields (only slightly)
  • Complete brake gear (rods/plumbing)
  • Some graphics (such as “2 inch HF comp shoes” on side sills)
  • AEI tags

This is not to say that this is a “cheap” version in any way – this model still exceeds the quality of some other RTR models, even including some newer Walthers releases (prior to their Proto line). The graphics are still razor sharp, and if desired, the modeler can still add most of the omitted details (e.g. hazmat placard decals, cut levers, air hoses). In fact, I think for the retail price of $22.99 US, this is indeed a bargain, especially considering it’s a new model, not a re-release.


            Rivet Counter Version

Whereas the Operator line is a basic-detail version, I’d say the Rivet Counter line is above par compared to other high-end HO manufacturer’s in terms of details offered and their execution. Several details are noteworthy and not common to many other HO offerings including:
  • Car ID stenciled on truck sideframes
  • Rotating roller bearing caps (Athearn Genesis did have these, but not blue ones)
  • AEI tags on side sills – that’s cool!
  • Full brake gear including rods, levers, and brake hangers
  • Orange dot painted on handbrake chain – how cool is that?!


I’d say that the level of detail in the Rivet Counter line exceeds any other modern HO tank car previously offered, including the Athearn Genesis modern LPG tank car which is also a highly detailed model. Retail price for the Rivet Counter line is $38.99 (US).

General Comments

While Scale Trains did go above and beyond in some of their details, there was one gaff of note: some cars did not come with the yellow reflective conspicuity stripes. These stripes were made mandatory on new equipment starting in 2005, long before these CPC-1232 cars hit the rails. First built in 2012, all CPC-1232’s are equipped with the stripes; I believe the omission of stripes from some models was an erroneous effort to make the model applicable to modelers who want to depict the pre-stripe era.

Overhead view of the two models - not much different from this angle as the basic tank shell casting and fittings and manway cover appear to be the same between the two models. 


Both lines come with well-designed packaging that includes a soft plastic sheet to prevent scuffs from plastic packaging shell (the manufacturers finally seem to have made this somewhat-standard on new models). The colour scheme and product numbering scheme for the two lines is similar, at first glance it’s difficult to tell which line is which. Personally I think two different colours would be a better way to differentiate the two lines, but it’s easy enough to do when looking at the front of the boxes.

A comparison of the ends of the two models illustrates the differences including: couplers, grab irons, graphics (stenciling on had shield and placard decal), roller bearing caps, and air hoses.

From above, the thinner head shield on the Rivet Counter line is obvious, though in my opinion, the head shield on the Operator line is not obstructively or obviously thick. Also note the wire vs cast plastic crossover platforms, and the grab irons on the Rivet Counter model.


Conclusion


This was Scale Trains’ first RTR offering in HO, and being a tank car (with a lot of exposed details), it’s not an easy thing to get right. And that they did – I think the split offering satisfies modelers at both ends of the spectrum, some desiring a few highly detailed models, others a whole train of slightly-less detailed models. The models are well-executed and if this is an indication of things to come from Scale Trains, Atlas, Athearn, Walthers, and others should take note that there is a new, serious, player in the game. I think their recent announcement of a carbon black hopper will only continue the success generated from the Trinity 31,000-gal crude oil tankcar.

'Til next time,
Cheers,
Peter.

Weekend Project – Athearn Tank Car “Repaint” 100th Post!



Over the weekend I turned an Athearn RTR UTC 30,000-gal tank car that was originally decorated for DODX into one decorated for Procor (PROX). 


Lately my free time has been reduced a bit due to work demands, so I thought I’d attempt more small projects that I could reasonably accomplish in the span of a weekend. This past weekend I wrapped up the first of what will hopefully be a series of regular updates on this sort of thing. And, as it turns out, this is my 100th post - how time flies!

This week’s project involves redecorating an Athearn RTR Union Tank Car prototype 30,000 gal general purpose tank car. I say redecorating because I didn’t actually repaint the car. Instead, I took a ready to run model that was painted for the US Department of Defense (DODX) and used a Badger air eraser to scrub off the unwanted lettering. The air eraser is essentially a small grit blaster that can use baking soda or aluminum oxide as a blasting media (I use baking soda, it’s much cheaper than aluminum oxide). I carefully masked the areas to be removed, which allowed for preservation of most of the car’s original finish. I specifically chose the DODX car to start with as it had substantially less graphics to start with compared to other paint schemes of the same car. Also, it’s somewhat less desirable, so it was much cheaper to buy than some of the other RTR schemes.

After masking the areas to be removed, I blasted off the unwanted lettering outdoors. Doing so does take a sizeable air compressor due to the amount of air required, at relatively high pressure. After I was done, I rinsed the car with water and let it dry overnight. I then used Microscale’s set 87-1466 (Procor/PROX, Various Tank Cars) to reapply the desired lettering. The set is a great improvement over some of their previous offerings for Procor equipment, but still contains a number of inaccuracies. Using the air blaster, I was able to preserve some of the original graphics such as the “2 INCH HF COMP SHOES” on the side sill and the COTS decals. Lettering was pretty straightforward, using prototype photos found on Chris Vanderheide’s Canadian Freight Car Gallery website. I found a car only two numbers away; I chose PROX 44815 since the number was already aligned in the decal set and wouldn’t require any splicing of individual digits. In prototype, the car is used to carry condensate, essentially a thinning agent used in crude oil pipelines to improve viscosity. The real-life car was built in 2007 at UTC’s now-closed East Chicago, IN plant, and is one of many so-called “short GP30’s” in the fleet (General Purpose, 30,000-gal capacity, less than 60’ in length over pulling faces).  I enjoy decal work since it’s easy to see the results of one’s work, and in this case, pretty quick; the car was decaled in less than an hour. After decaling I used Testor’s gloss coat to seal the decals to the car. I will eventually weather the car lightly, as I model up until 2010, so the car would still be relatively clean and shiny in my modeling era.

‘Til next time,
