and Fort Erie. Welland was also the terminus of the Toronto, Hamilton & Buffalo Railway's track (the link to Buffalo, New York being via the CASO line). The T, H & B ran joint passenger trains with the New York Central to provide through service between Toronto and Buffalo (via Hamilton, Ontario and Welland). There was also a Canadian National Railways (earlier, Grand Trunk Railway) line running in a North/South direction and crossing the CASO line at Welland Diamond. An interlocking tower (WX) stood here. Another line ran through the Dain City area of south Welland. This was the Canada Air Line Railway, and was also used by the Wabash Railway. Later, it became the Cayuga Subdivision of the Canadian National Railway. Lastly, the Niagara, St. Catharines and Toronto Railway provided electric radial service from Port Colborne, Ontario to Thorold, Ontario via Welland. Passenger service ended in November 1959, but the tracks remained in freight use until 1981 when a trestle over the Welland River became unsafe and the line was removed from service. The relocation of the Welland Canal in the early 1970s caused massive changes in the local railway network. The new route of the canal was previously crossed by five separate railway lines. The new segment of canal would have no bridges, and just one railway tunnel, so all of these routes required redesign. The two branches of the CASO line, plus the Cayuga Subdivision were re-routed through the Townline Tunnel, while the North/South Canadian National line was split and discontinued as a through route. The station at King Street was abandoned and demolished. It was replaced by a new station outside of town, but passenger service ended soon after. Today, Welland is the location of one of only two remaining railway crossings that span the Welland Canal. The Townline Tunnel is built for three railway tracks, but the center track was removed in the early 1990s. Now, only two tracks run through the tunnel. The north track is the Canadian Pacific Railway Hamilton subdivision. The south track was formerly the Canadian National Railway Cayuga subdivision. Since the abandonment of the majority of that subdivision, operations on this track were limited to occasional trains interchanging with Trillium Rail's Port Colborne Harbour Railway. Today, Canadian Pacific also uses this track as their "Brookfield Siding". There is also a Trillium Railway (Port Colborne Harbour Railway) north-south line running through
