The matter of ICC regulation and reporting gets confused sometimes. Take the Butte, Anaconda & Pacific.
The BA&P was treated as your ordinary mining company subsidary common carrier until 1913, when electric operation took over most of the line. Then things get interesting. The ICC treated it in some ways as an interurban, and in others as a steam railroad after the line was electrified. Operating statistics for the BA&P, which were published as part of the steam railroad data through 1913, were dropped, and the company treated as an interurban. However, when the passenger train, powered by a single unit electrtic collided with a pairo of freight motors, there was a regular ICC accident investigation which was published along with all the other ICC accident investigations.
Compare with the neighboring Chicago Milwaukee & St. Paul, which was always covered in the ICC's annual compilation of steam railroad statistics - even after over 600 miles were electrically operated.
Dot you just love bureaucracy?
