As demand for coiled steel increased, problems using standard gondolas led to new purpose-built coil cars with an interior trough in the 1960s. Today's cars are similar, but are built lighter and feature a one-piece removable hood to protect the valuable loads from the weather in transit.
 
Based on a 42' prototype with a distinctive fishbelly sidesill, these models feature prototypical painting and lettering, see-through walks, removable hood and inside floor detail.
