On a steamer, the pilot wheels are all counted, such as a 4-8-4. You're saying on the centipede the pilots are counted as axles, not wheels. Is this unique to diesels, or just to the centipede?? :dunno:The Baldwin DR12-8-1500/2SC "Centipedes" had a 2-D+D-2 wheel arrangement. The front 2 axels and rear 2 axels were not powered, but designated as pilots.
They had a power rating of 3,000 horsepower. I believe they were 91 feet long.
