Below is the report filed by the Niagara Junction Railway with the New York State Board of Railroad Commissioners for the year ending June 30, 1904.
Equipment was unchanged from the previous year: the same two locomotives, one with six drivers and one with four, and six flat cars.
It notes that the railroad had 13.77 miles of track, down from 13.81 miles in 1903. Though the company didn’t show any increase in the number of miles of track, they spent $1,435.74 on “Construction of new sidings to factories.” I don’t know if they took other track out of service when they built the new sidings or if they built the sidings but they were the property of the factory. Maybe if the sidings were on another company’s property they were not included in the railroad’s report.
The report listed six unprotected highway crossings and one highway crossed over grade (the street went over the railroad), which was unchanged from the previous year. There was also a listing of one highway crossing undergrade that was new this year. It refers to the project done by the city of Niagara Falls to put 10th Street under the New York Central Railroad, Erie Railroad, and Niagara Junction Railway tracks. This underpass is still in place even though the tracks are long gone.
The 1904 report showed the same railroad crossings as in previous years: two steam railroad crossed under grade (the Niagara Junction Railroad crossed over the steam railroads), one street railroad crossed under grade, one street railroad crossed unprotected at grade.
