North American railroads with HO scale models on TrainDex

North American railroads are classified by the Surface Transportation Board into Class I (annual revenue over $1 billion), Class II (regional), and Class III (short line) categories. The seven Class I railroads — BNSF, Union Pacific, CSX, Norfolk Southern, Canadian National, CPKC, and Ferromex — haul the majority of U.S. and Canadian freight and are the most popular road names among HO scale modelers.

Fallen flag railroads like Penn Central, Conrail, Southern Pacific, and Milwaukee Road remain highly collectible in model form, with manufacturers regularly producing new runs in heritage paint schemes.
