The City of Ottawa is exploring anti-icing strategies after freezing rain and ice shut down the LRT twice earlier this year.
In a report prepared for an upcoming transit commission meeting, city staff say Rideau Transit Maintenance will be testing an anti-ice chemical in October to prepare for the winter. The chemical sticks to the overhead wires and helps prevent ice from building up during freezing rain.
Additionally, the maintenance company is considering installing a monitoring system on the trains, which would provide real-time data and video of the system’s wires, in order to monitor its conditions.
A diesel rail care mover known as a “shunter” is also being considered in order to move trains short distances in the event of a power outage.
Long-term mitigation options include micro-climate weather stations at some train stations.
“A weather station would be a more accurate way of gauging changing weather conditions on the line, which could aid in improved reactions to ice events,” the report reads.
The report does not include the cost of these potential ice mitigation techniques.
On Jan. 4, 2023, the LRT was shut down for six days following a freezing rain storm and ice fog from the nearby Rideau River. The storm caused ice build-up on the overhead catenary near Lees Station, with a citizen’s video showing alarming flashes and sparks as a train sizzles its way along the line.
Both eastbound and westbound trains ground to a halt, and attempts to tow the stalled train with a third rescue train were thwarted when a train wire snapped.
An investigation found the copper line got so hot it melted.
Trains were halted again in April after an unseasonal ice storm on April 5.
