Introduction

Atlas Model Railroad Company, Inc. offers this Atlas N Trinity 25,500 Gallon Tank Car.  Part of Atlas' Master Line, it has been released eight times since it debuted in May, 2009, in more than two dozen road names.  This review looks at the tank car decorated as GATX (Soy Power Bio Fuels) 30829, item 50 006 181.  Atlas writes of this model:

Atlas’ model is of the Trinity 25,500 gal, insulated, general-purpose design. This was introduced in 1986 and production continues today. There are at least 13,000 presently in service. Typical commodities include vegetable oil, tallow, styrene, benzene, asphalt, biodiesel, acrylates, and numerous other chemicals.

TrinityRail's website states that this tank car features optional configurations to meet a customer's requirements.   Join the car inspector for this walk-around.

TrinityRail

TrinityRail, the railroad part of Trinity Industries of Dallas, builds the prototype for Atlas' Trinity 25,500 gallon tank car (TrinityRail lists it as the 25,498-gallon tank car).  Trinity Industries started in 1933 as Trinity Steel, which built tanks and containers for the oil industry.  In the mid-1960s they began building freight cars.  This must have worked well for them as in the 1980s they began gobbling up other rail car companies.  They now have the rights and designs to Thrall, Greenville, and Pullman-Standard, and others, and are considered the largest freightcar builder in North America.  Trinity offers over 250 freight cars types and variants:

• autoracks
• flat cars
• gondolas
• hoppers
• intermodal container cars
• steel coil cars
• tank cars.

This release of 25,000-gallon Trinity tank cars features new paint schemes.

Trinity's basic black is punctuated with splashes of color of the high-visibility yellow bars along each side, the REG Marketing & Logistics Group, LLC blue logo, and the big green Soy Powered logo.  Plenty of informational stenciling, too, including 2 Inch HF Comp Shoes, Consolidated Stencil, and more than that.  HAZMAT placards are not used but the brackets are present.

Walkaround

Atlas' Trinity 25,500 gallon tank car features:

• Accurate painting and printing
• Numerous detail fittings and components specific to prototype
• Highly detailed body with prototypical jacket seams
• See-through walkway and top platform grating

Starting at the rails, the model rides on plastic wheels in plastic standard trucks.  These feature good detail for the scale.  They are mounted to body bolsters which support the tank.  This design is known as a stub sill tank car and the draft gear is mounted to the sills, under the walkway.  Handrails, hand brake gear on the B-end, and Hazmat placard holders are mounted on the sills. 

Moving up to the tank you can see that this model is molded with 10 sections - eight of the same size, and two narrower segments under the crashbox (top platform grating).  While the lap welds are difficult to see in photos of real tank cars, those segments appear authentic for actual Trinity 25,500 cars.

Performance

My sample rolled smoothly over code 80 turnouts both through and towards the points.  To assess how the car alone would perform without stabilization from other cars or the "0-5-0 finger switcher" I gently tipped the layout to let gravity power the solo car along its route.  Smooth and stable.

Coupling it to other N cars I deem the couple height is in specifications.  I weighted it at 1.1 ounces which aligns with NMRA standards.

Conclusion

Modelers of N scale subjects of the late 1980s until today should consider filling their roster with this good looking Atlas Master Line modern tank car.  It performs without trouble, looks sharp and accurate, sporting detail on available in larger scales until a decade or so ago.  Atlas' paint and printing leaves nothing to be desired.  Happily recommended.
