Over time , neighbourhoods began to develop outside the original city boundary and were amalgamated into the city proper . One of Halifax 's largest megaprojects in history saw the completion in 1918 of a major railway line through a deep rock cut for several kilometres parallelling the shore of the Northwest Arm to serve a new railway station at the south end of the city 's business district . The new railway line had been under construction by the Intercolonial Railway and later Canadian Government Railways at the time of the Halifax Explosion , which blocked and badly damaged the city 's North Street station ; the new railway line through the South End was rushed into completion to accommodate the unexpected disaster . One result of the building of this railway line has been to geographically isolate parts of the peninsula , creating opportunities for wealthy and exclusive neighbourhoods to develop . Another legacy of the blasting work created during the construction of the South End railway cut was the infilling of parts of Halifax Harbour and Bedford Basin to create railway yards and freight and passenger ship docks
