Rock Island Diesel Roser: All-Time
Published: March 19, 2025
By: Adam Burns
The CRI&P began testing early diesel switchers during the 1930s and was quick to adopt the motive power as main line models became available late that decade.
While the railroad predominantly preferred Electro-Motive and Alco products it acquired models from all of the major builders, including a few from Lima's brief catalog. The information below covers the Rock Island's all-time diesel roster.
