HO scale Thrall/Trinity 42-foot coil steel car

Having trouble viewing this video?   Please visit our Video FAQ page has added a Thrall/Trinity 42-foot coil steel car to its HO scale Rivet Counter line. The injection-molded plastic model features wire and etched-metal details, a simulated wood trough floor with a hand-applied wash, and new American Steel Foundries 100-ton trucks with rotating bearing caps and raised foundry data.

The prototype. The Trinity 42-foot coil steel car was originally designed by Thrall Car Manufacturing Co. in the mid-1990s. TrinityRail purchased Thrall in 2001, and continued to produce the 42-foot coil car until 2012.

Our sample is decorated as CSXT no. 493005, part of the railroad’s 493000 through 493524 series. The full-size cars were built by TrinityRail under Files F11025 and F11029 between March and July 2012.

Sales literature on the TrinityRail website listed features of the prototype car, including running boards on all four sides, wood trough flooring to protect the edges of the coil steel, and a single stackable coil hood. The car can handle coils of various lengths between 30" and 84" in diameter.

The model. The Thrall/Trinity 42-foot coil steel car is part of the company’s premium Rivet Counter line. The coil hauler is offered in three body styles, reflecting the car’s history: early Thrall, intermediate Trinity, and late Trinity. Our sample is based on the latter, with the end handrails fastened to the car body and a vertical stiffener on top of the draft-gear box. The other two versions have the end rails attached to
the hood ends.

In addition, there are six hood versions. Depending on the style, there are up to 47 separate parts on each hood, including a plastic lifting bail, photo-etched metal handrail stanchions, and wire handrails.

The car includes four modeler-installed hood guides, four load dividers, and five coils (two each 5'-9" and 6'-6" diameter, one 7'-0" diameter). Two sticker sheets are included to wrap the coils, as seen in the photo on the opposite page.

An exploded-view diagram shows the model’s construction. At the core is a one-piece body framed by a see-through etched-metal walkway. Below that is the underframe, consisting of the draft-gear boxes, center sills, and crossbearers; the bolsters are separate parts.

The well-rendered brake system includes the air reservoir, brake cylinder, control valve, and related rods and levers. Because of the car’s construction, many of these parts are visible from most layout viewing angles.
