For both the B&OCT and PCC&StL, Brighton Park was one in a string of non-interlocked railroad crossings at grade with others at Ash Street, 26th St and 12th St. Maximum speed on the route was between 20-30 mph. Interlocking the Brighton Park crossing would have been of limited value without upgrading the entire line. As passenger traffic on the route dried up and the railroads entered financial hardship, investment in the line became less and less of a priority. With the formation of the Penn Central and later Conrail, the PCC&StL and CR&I lines through Brighton Park were united under a single railroad. The Panhandle route was ultimately abandoned with Conrail shifting traffic to the C&RI, ripping up the two Panhandle tracks, thus reducing the number of tracks crossing the Alton to 5. Under Conrail the CR&I was designated as an industrial track, its lowest classification. Since the PRR era crossing agreement with the Alton successor Illinois Central Railroad was still in effect, Conrail had little incentive to upgrade the signaling on the line.
