When the LT&L purchased the CAR’s rail lines in Québec, Maine, and New Brunswick, they split the surviving lines (far too many of the CAR’s rural lines had no traffic, or had been knocked out of service by flooding) into three groups. The Acadian (northern) lines went to the PRR(y), the mainline across to St John & St Stephens became part of the LT&L, and a small handful of teetering on the edge lines centered at Fredericton became the New Brunswick Rail Road.
The NBRR consists of five branches;
The Fredericton Line, running from Fredericton Junction to Fredericton
The Minto Line, running from Fredericton to Chipman. This line was used primarily for coal shipments from the opencast mines NW of Minto, and when they were shut down in 2008, the NBRR abandoned most of the line, leaving only a stub serving the J.D. Irving mill in Chipman.
This stub was electrified (@1500 VDC) almost immediately after the abandonment of the rest of the line, and now operates using class 320 motor #1077.
The Florenceville Line, running on ex-(OG)NBR trackage from Fredericton to the St John River at Hartland, and from there up to the McCain food processing plant in Florenceville.
The Woodstock Line, which runs from the Florenceville Line at Pembroke Junction south to Woodstock. This line was out of service when the NBRR was created, but in 2002, the NBRR replaced the washed out spans of the bridge at Sharpe’s Island and resumed service to Woodstock (there had been a few other shippers south of Woodstock, but even with the offer of transloading shipments they’d all dried up by the time the new spans had been placed and the west side line had been connected to the rest of the Florenceville Line.
The Nackawic Line, running from a junction with the Florenceville Line (a couple of kilometers SE of Millville) down to the St John at Nackawic.
The Welamukotuk line, running on ex-CN trackage from Fredericton through the Oromocto first nation and terminating at CFB Gagetown.
None of these branches are particularly busy, but are reasonably sited enough to hopefully not be destroyed by storms, flooding, or ice jams (there are only two bridges crossing the terrifyingly ice jam prone St John; the recently rebuilt bridge on the Woodstock Line and one in Fredericton, which is pinned between a pair of highway bridges that help protect it from the spring thaw.)
The NBRR serves these branches with the previously mentioned class 320, plus a handful of DL10, DL10b, and DL16 locomotives that have been pushed off other Parsons Vale railroads by the slow march of electrification.
