It was as if all the affected passengers were going to left high and dry, when a temporary bus service was going to fill in the gap.

I have heard so many silly arguments from this so-called group of rail experts making outrageous claims of where trains can run and how easy it is to implement. We can double the number of O-Trains crossing active rail lines. No problem, eventhough it was difficult to get permission to run the current number of trains. Sure, it will be easy to double the number of trains. I bet!
Yes, it is. We didn't worry about crossing roads downtown or in Riverside South, but somehow crossing low-use rail lines is a problem? If anything, your comment shows how ignorant you are of how rail operates. Please head down to the nearest road-rail crossing and watch how long it takes for a VIA train to pass and note how long the lights/gates are on for (you might want to consult the schedules first though). Then go to a traffic light and note how long those cycles are. The results might surprise you. If we can deal with the latter we can manage the former.

As for permission, considering that David Collenette, the former federal transport minister, headed the Mayor's Task Force and even had the temerity to consult - yes, I know this is shocking in Ottawa - the director of the Rail Safety Branch at Transport Canada, I'm sure it can all be done. In fact, here's a quote from page 74 of the report, which I trust you read, right, rather than just dismissing it out of hand?:

"A delegation from the Task Force met with senior Transport Canada railway safety officials to present an overview of its recommendations and start a dialogue on safety-related issues. The most fundamental question the Task Force asked related to mixing passenger and commercial rail traffic. The Task Force’s recommendation to use existing rail corridors necessitates track sharing between passenger and freight trains. In the past, this
has proved a stumbling block. Consultations with Transport Canada railway
safety officials were fruitful and indicate that there should be no regulatory
impediment to mixing freight and passenger trains."

Damn it, eh? They thought about that one. Amazing what happens when you actually, you know, consult. Guess that bit of FUD is out the window now.

Conversion of the Transitways to rail is a breeze. Even buses, could continue to run on the Transitway while rail is being laid. Come on! The Transitway will be realligned, stations redesigned, the roadbed dug up and electrical service added. Once conversion begins, there will be no buses on the Transitway.
If the "shut-it-down" mentality triumphs, you're right, there won't be buses during conversion. But that doesn't mean it has to be that way. There are ways around that problem. The overhead electrics can be put in prior to conversion, or even after if we use dual-mode vehicles like Alstom's Citadis. I know - "it can't be done!" - except railway electrification occurs ever

Then there was the long list of problems with the N-S LRT route, yet we had detailed engineering designs and a fixed price construction contract. It doesn't sound like those problems are so serious, otherwise why would multinational companies sign a contract to build it. There always seems to be a double standard. A sharp turn going into Hull from the Prince of Wales bridge is just fine, thank you very much, yet much more gentle curves running through Riverside South are considered unacceptable. This is supposed to be modern light rail, not trudging 19th century steam trains.
You've lost me. The curve from the Prince of Wales Bridge into Hull IS gentle. It kind of has to be. It is, after all, a curve on a railway. It's light rail that can turn sharper curves. That's what allows it to head down city streets if need be. At any rate, it's the City that insisted on a sharp curve at Bayview (between the bridges for the eastbound track) rather than making use of the pre-existing gentle railway curve next to the City Centre complex, which the NCC conveniently put up for sale just as it was needed but for some reason the City didn't buy. You'll find that the N-S LRT curve at Bayview is much sharper than the one coming off the north end of the Prince of Wales Bridge. I think the criticism of the curves in Riverside South was that they existed at all considering that there was nothing much there and no obvious need for them. My guess is they were planned to increase the amount of developable land near stations since a curvy route increases frontage along the line. That might be forgiveable if it was mainly commercial/employment zones with a view to increasing reverse commuting, but it wasn't: it was mainly medium-density residential. Acting as a neighbourhood transit service is not exactly the purpose of multi-hundred million dollar rapid transit line. Of course, that's the nub of it: it was never intended to be such; it was just promoted that way. The "real" rapid transit service was to remain as BRT.

Allowing a freight train to travel the line every once in awhile as is the case now is likely the the mix of freight and passenger trains talked of above.

Having an LRT cross freight track means just one thing: you have to buy LRT cars that are FRA compliant. I don't think anyone builds those. Plus, you would have to get permission from the railroad for infringing on their corridor, and no railroad wants to write down an asset like a main line due to capacity restrictions. It is possible in future they will need to build new HSR tracks next to the freight mainline - who would be responsible for grade separation then?

I have heard of these problems in the states with track sharing freight and passengers. It's generally(always) not allowed.

It does seem strange that cars and trucks can cross freight tracks at rail crossings but a light rail train cannot though. Does it have to do with the length and slow acceleration?

Yeah well, it is the same way here. FRA regulations are in place to stop passenger deaths (or at least limit them) in the event a freight train hits a passenger train. Nothing to do with length and acceleration, all to do with survivability of rail cars, freight and passenger.

The part I don't understand is crossings. Why can bus loads of people cross freight tracks but light rail trains cannot cross these same tracks?

Yes, it was.

The NS LRT would have been in place today, drastically increasing the reach of rapid transit in this city. Planning would have been completed for the EW line.

Instead, we've barely built anything in the last 3 years, and will barely build anything for many more years.

The disaster is that our transit system has become stagnant.

But I guess you don't care about transit, just rail.

Different laws cover the different things and sometimes laws are not very logical for today's perspective. But not allowing wagons and horses to cross train tracks in the 1800s would have been rather stupid no? Accelerate that decision to today and you have the disparity.

Probably comes down to the old human brain's lack of capacity for logical risk assessment. Some people are afraid of flying yet drive every day, a much more dangerous activity. In Toronto you see it in the people complaining about more diesel trains running near them (they are worried exhaust will cause childhood cancers) yet they don't complain about the four lane road in front of their house.

Sounds like you are saying ALL crossings should be grade separated?

"fix it don't nix it" - Alex Munter had the best idea. The N-S line had some good and some not so good.

No. Just because it is illogical if you were forming a new system today, it doesn't mean it is logical to change it.

The main reason is because trains are much heavier than buses and take longer to stop, and the slowdowns in the diamonds create poor reliability for a large-scale LRT system.

As for road-LRT grade separations, they should generally be as follows:

1) If the frequency is less than every 5 minutes between trains at rush hour, it should be fully grade-separated for safety and operational reasons. Such would most likely only be the case between Hurdman and Lincoln Fields at the ultimate stage.

2) Any crossings of expressways, freeways or conflicting railways should be grade separated.

3) Crossings of arterial roads would be on a case-by-case basis. Grade separations should normally be provided only if safety, geotechnical or operational reasons warrant (i.e. a very busy street which would have its level of service break down) or if it is adjacent to a freeway or railway corridor that is grade separated. Any existing grade separations (such as on the SE Transitway) should certainly remain though.

4) Crossings of collector roads should generally be at-grade in the suburbs unless safety or geotechnical conditions dictate otherwise, since traffic flows are seldom affected.

Sorry, I won't take back any of my comments.

At the present time, we have special permission for the O-Train to cross active heavy rail tracks. This is a safety concern. The more O-Trains that cross those active tracks, the higher the safety risk. At some point, grade separation will become a requirement. Has this really been addressed?

As far as mixing freight and passenger trains, I don't dispute that this is possible and it happens every day. That was not my point. My point was that you have single track rail line and only so many trains can run on that track and the heavier the trains, the slower the acceleration and deacceleration. In other words, the heavier the trains, the farther they have to spaced out. Furthermore, it is unlikely that FRA and non-FRA trains will be allowed on the same track at the same time. This again is a safety concern because of the possible damage and loss of life if these two types of trains collide. So, I cannot imagine O-Trains being allowed to share track with Via Rail Trains. What would be needed for commuter service between Barrhaven and the Via Rail station is FRA compliant heavy rail commuter trains. Of course, my overall concern is the need to have bus service at both ends of that line and I question whether that can possibly deliver faster service.

“It was quite a debate between staff between light metro or light rail and we really put our recommendations to the test,” she said.

In a study done by Delcan Corp. comparing light rail and light metro — or heavy rail —light rail came out on top because of the technology’s ability to blend with the existing urban fabric.

“One of my take aways from the technology forum we had in June was the enviable position Ottawa was in because of our existing network of corridors and our dedicated ridership,” Schepers said. “So we had to look for the technology that fits best with that framework.”
The study showed that while light metro could handle a higher capacity of passengers, there was a potential for it to divide the transportation network. The system would require dedicated corridors and a segregation of the western leg of the system. It could also represent higher operational costs.
http://www.yourkemptville.com/NepeanThisWeek/news/article/17347

If you have BRT corridors (and we keep building BRT corridors) conversion to light rail might as well be ALRT - the hard work is done! The "western leg" will either be segregated or it will run into delays which may make the system slower than buses and lead to lower ridership from Kanata. Express buses will also be lost, so no service improvement there.

They are facing a cost crunch and starting to cut corners which will have repercussions down the line. If money is an issue, tell Larry he can't have his tunnel and put light rail on the surface same as they do in Calgary.

Calgary is in the process of creating plans to build a tunnel under the downtown area. Honestly its best if we spend the money to build the tunnel now rather than later. Our buses are running at full capacity during rush hour in the downtown area and we need to find another way to get commuters across the city quickly and more efficiently. Building this tunnel will save us a lot of money and complications in the future. Just get the construction over with so we can move on...

I agree, but there is no money. So if corners need to be cut, the tunnel should be first to go. It should be easy enough to build a tunnel later (as Calgary is doing) plus the surface lines can still be used as a streetcar line.

I do think it is the best plan given the options (minus the tunnel, which needs more serious cost discussions). The only change I would make is the existing O-Train in the ultimate stage (i.e. after extending beyond South Keys); I would leave it unchanged while maintaining the Southeast Transitway as the main route to downtown from the southern areas. Also, the Gatineau service - in the ultimate stage - should be via LRT across a twinned/reconstructed Prince of Wales Bridge, with one branch to Aylmer and one to old Gatineau.

Just a curiousity, looking at all the plans, what would be better for serving the southeast area - operating via the Alta Vista corridor (via the hospitals) and Conroy to Hunt Club (new corridor), or Southeast Transitway to Hunt Club (branch of the existing corridor, like the current Route 98)?

Another Delcan report. Another disappointment. No wonder we can't get anything going with this sort of "information".
