The Herald Square merge on the BMT Broadway line is considered one of the worst in the NYC subway system due to its inefficient "reverse branching" design. This design significantly limits the overall capacity of the line, causing frequent delays and lower train frequencies. While other junctions might be problematic, the Herald Square merge uniquely hinders capacity in the crucial city center. The merge's existence is attributed to the need to bring more trains to Queens, especially given capacity restrictions in lower Manhattan caused by ancient signal systems. However, with the upcoming implementation of modern signaling technology, there's a strong argument to be made for removing the Herald Square merge entirely, which would allow for more efficient train operations.
