Egan: How winter-ready is our LRT after snowflake system?


Only seven weeks before the transfer limit for the $ 2.1 billion LRT system – and a week before the bats of snow – a specialist rail network failed and hit essential transmission equipment on the track.

There is further evidence that the city's public transport initiative, which is being transferred from the Rideau Transit Group builder on March 31, will lose the closing date, but there may be shortcomings are only disclosed in winter under extreme weather conditions.

The director of the city's rail construction program, Michael Morgan, confirmed a wing employed by RTG maintenance departments and damaged parts of the system on February 6.

Not providing much detail, Morgan said that the plow had damaged two "balises" known as signal transversers lying flat between the tracks, slightly higher than ground level connections.

The translators provide detailed paper information and an important part of the "train management system." (If only indicating clearly, the location or space between trains is not only a crucial safety component but is essential to run 15 double trains at peak times at peak times, on a timetable, ensuring a service through the city tunnel every three or four minutes.)

There are more than 800 gaps along the 12.5km of the Confederation Line, which has proven for months.

In a written reply, Morgan said that there was a redundancy that had been included in the system to ensure that damaged balise did not interfere with the service. He said that both damaged devices were repaired and "did not affect testing activities." Although the city had been asked, it did not explain how the balises could be hit by what happened to the event.

The event mentioned in the February 12 presentation to the Mayor Jim Watson and the members of the finance and economic development committee by CEO of Peteride's Rideau Group Peter Lauch or John Manconi, the city's general transport manager.

That city hall meeting was dark enough. Manconi outlined eight elements still outstanding before RTG transferred the system in a "revenue service" condition, or was willing to accept passengers. The words "snow pulling" have never been mentioned but slippage was listed which listed "operational readiness in all areas, including maintenance" as among the contractual RTG requirements.

He took some proof but both Manconi and Watson said they were extremely suspicious – despite the security of Lauch – the LRT would be ready to take over the city on March 31.

Damage on February 6 raises a clear question. If it was not snowy then going smoothly, how was it paid on February 12 and 13 when Ottawa was buried under 31 inches of snow?

Not good, we understand. CBS reported this week that "a light rail vehicle" had stuck between Hurdman and Lees stations for two days, after a storm, and had to be taken to a maintenance yard.

On Wednesday, at a meeting of the city's transport commission, Manconi was asked for his confidence in the rail system to operate effectively in severe weather conditions. He would not look at the topic, saying that such questions should be held for the forthcoming finance committee meeting, where light rail updates are usually introduced.

He noted, however, that two trains were tested on the afternoons of Wednesday.

Curiously, the city reported to this newspaper last week that the trains, in fact, were tested during the storm.

"RTG was running trains through the snow stall last night and it continued to run trains until 3:30 am on Wednesday morning (February 13). Trains running during this type of snow event helps prepare how ready is the trains and systems operating during the winter, confirms that the key system systems are being implemented, including switching heaters, and validating the process and abilities of the maintenance and retention team. # 39; r system is clear of snow. "

So how is snow being cleared from LRT tracks?

The city says that Rideau Transit Maintenance, who has a 30 year contract, uses at least three types of specialized equipment, using a combination of blade, buckets, sprayers, rotary rushes and forced hot air blowers to keep & # 39; The tracks are clear and switches are free of snow and ice.

In addition, the city says train frequencies – together with a repeated connection of the power system overhead – helps keep both tracks and wires free of construction.

The abstraction problems occur at a time when RTG already has a full load of deliverability. As last week, only 14 of 34 trains had been fully certified, the tunnel ventilation system had not been fully tested and it was not yet running a compulsory non- day-to-day payment of 12 days of simulated daily service.

And now this. It's just a pain that grows in the day before the launch day is to break some transversers. Or no.

But here's the route we are in the pipeline: RTG has been as close as possible, all scrap of news – flood stations, lousy concrete, computer systems are missing – is being consumed with a cup of doubt.
