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, 1903.
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 13.81 miles of track, up from 13.33 miles in 1902. It also showed the railroad as spending over $1,000 that year on construction of a new siding.
The report listed the same road crossings as in 1902: six unprotected road crossings and one highway crossed over grade (the street went over the railroad).
The 1903 report shows 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.
