The main features of this line are shown in the table below. The O Train runs from Bayview station (north) to Greenboro station (south). Passengers travelling southwards should read the table from top to bottom while those travelling northwards should read from bottom to top.
History of the line
The line between Greenboro and Chaudiere Junction was built by the Bytown and Prescott Railway as part of their line between Prescott on the St. Lawrence River to Ottawa, Sussex Street. This section was built in November 1854 and opened to traffic in December 1854.
The section of line from Chaudiere Junction to the switch leading to Bayview Station was built by the St. Lawrence and Ottawa Railway, the successor to the Bytown and Prescott, and opened to traffic on December 13, 1871.
line was acquired by
the Canadian Pacific Railway in 1884 and was subsequently sold to the
city of Ottawa
short length of
line from the
switch to Bayview Station was built for the opening of the
O Train on October 15, 2001. When originally built, the line crossed
Rideau Canal at Dows Lake on a swing bridge and then skirted Dows Lake. It then ran at ground
level with many
crossings at grade with city streets.
order to eliminate these crossings, the Federal Government funded the
tunnel under Dows Lake as well as the cuts leading to it. The lowering of
the tracks and associated grade separations was completed in 1966.
Kilometer posts are located on the west side of the line while signals are mainly to the right of the train in the direction of travel (i.e. on the east side for northbound trains and on the west side for southbound trains.

Diesel Cars (RDC's) running between Ottawa Station and Montreal via
Hull/Gatineau and Lachute.

This was originally built about 1912 to allow
trains to pass under the railway. They were used to transport
earth and clay from the vicinity of Hartwell's Locks to fill in a
swampy area, including an inlet of the Rideau River, at the south end
of Bronson Avenue, now known as Brewer Park. It was rebuilt
1926 as a concrete slab underpass. For further details of the narrow gauge railway see ../circle/findings3.htm#CUtramway

The first bridge at this location was a wooden one
