  1. Last week
  2. Here's the updated version https://imgur.com/gallery/XlFOG59
  3. While the outside temperature did not reach 35C, the temperature of the tracks in the blazing sun will be much higher. I think that's the real reason why we have the slow order
  4. The grilles at Parliament are a tad bizarre and, likely, the one on O'Connor that deals with the Heritage Place exit looks like it could be an add-on. The large grille in front of the Queen entrance to WEP, however/moreover, is exactly in the location where the glass elevator pavilion marked Parliament appears in the Citizen photo you uploaded. At Rideau there are only two grilles, pretty much equal in size, and one on each side of the street. I haven't examined the fan situation at Lyon but I have at Rideau and it appears the fans are mounted in the vent shafts. If you stand on the western end of the westbound platform I believe you can see the exhaust mechanisms in the shaft at the west end of the eastern platform. There would appear to be no such mechanisms installed in what I think to be the abandoned elevator shaft in front of WEP that now serves as a sort of passive chimney vent for the station below
  5. The double grill at O'Connor and Queen, next to the the Heritage Place entrance is above the existing stairs. It looks very sloppy IMO. Lyon seems to be the only station with straight forward ventilation shafts; one on each end of the station cavern, both the same size. I always imagined large fans at each end to suck smoke out of the station should there be a fire. Not really sure how that would work with the mess of various sized, randomly placed grills at Parliament and Rideau.
  6. Here's the image of the original WEP entrance. Entrances? https://www.cbc.ca/news/canada/ottawa/downtown-lrt-stations-to-get-building-entrances-1.3071029
  7. I suspect that the rebuilt Inveros (which 4202 is not by the way) will last a few more years, possibly at least three (so 2023 or around that range). As for unrebuilt Inveros, I think they'll continue to retire small batches at a time when new buses come in (they haven't been doing much of that since March). I suspect that the entirety of those will be pulled off by late 2021. We have 133 left unrebuilt (and 62 rebuilt units), so if we get another batch of LFSs in the future (it hasn't been talked about yet), then most if not all (excluding rebuilds) will likely retire at that point. Correction about my above post: Nine Inveros were retired in March and four were retired in May.
  8. Apologies for the lengthy delay in reply. I doubt it was to ever come inside the WEP--the below/above grade of the WEP in relation to Queen Street, the difficulties with the TD bank space, etc. As mentioned, directly outside the WEP entry onto Queen is a large grille, equal in square footage to the elevator bank shaft at O'Connor & Queen. If you are there after dark you can see down directly to the unfinished eastern end of the mezzanine level. Depending on how this would have been/could be configured, there is room for 2 or even 3 elevators to street level. I also measured the square footage of the venting grilles installed at sidewalk level at each of the 3 underground stations. It figures that the deeper the station, the greater the overall diameter of venting shaft. That would mean Rideau would have the most venting grille work at street level, Parliament somewhat less and Lyon the least. Here's what I found: Rideau has two sets of grilles on either side of the street. The total square footage is 630 sq.ft. of grille. As noted, Lyon, the shallowest station, should have less need for grilling. And that's confirmed by the overall square footage total of 525 sq. ft. of grille. Parliament, deeper than Lyon but shallower than Rideau, should be somewhere in between. It has, however, 1,100 sq. ft. of (apparent) grille work at sidewalk level. Most is on the south side of Queen but there is a small (100 sq.ft.) grille on the north side of Queen/O'Connor. The easternmost set of grilles, which I suspect cover the shaftway (visible at night as it's lit from below but not enough to see down during daylight) in front of the WEP are 11x40 feet = 440 sq.ft (the current double elevators occupy a space of 12.5x30 feet). Deductng 440 from 1,100 = 660 sq.ft, approx. the same as at Rideau and somewhat more than at Lyon. So, yes, those early sketches, I believe, were more or less in line with what was proposed and the second elevator shaftway to Queen St. would have been roughly similar in look to the one at the corner of Queen & O'Connor
  9. Hi Shane, I understand that when Continuous Welded Rail (CWR) is installed, it is done so at what's called a Stress-free Temperature. The rail is thermally or mechanically stressed to a point where it will experience the least stress possible given the hot/cold extremes of the local climate in which it is installed. So, the Stress-free temperature will vary by location. According to Wikipedia, in the USA, this temperature is most often set between 35 ad 43C. It was not this hot in Ottawa last week. It can happen that even when the appropriate Stress-free temperature for a particular CWR is properly determined, track can still buckle or lose alignment. Perhaps that's what could have happened with the Confederation Line. But I fear we'll never know precisely what's up due to the consortium's ultra secrecy about sharing information (both OC Transpo and RTM are equally in need of upping their games here). It could be that the CWR Stress-free temperature for the Confederation Line has been set a bit low or it could be that Ottawa is just a wild climate to have CWR that both won't crack in the cold and distort/expand too much in the heat. Nevertheless, while trains running on CWR do slow down during extreme heat, I'm unaware of other systems having to slow down to such creepingly slow speeds. Other factors that affect CWR rail distortion in extreme heat include the ballast (quality and installation), track shoulders, and the sleepers. Somehow I would not be astounded to learn that some of these components are borderline substandard quality and/or incorrectly installed (like the catenary system and overhead wiring infrastructure)
  10. Any guess how many more years the Inveros will be with us in the fleet? Seeing the above post that 4202 is still in service... it is clearly the oldest bus in the active fleet.
  11. The changes to come for Tunney's Pasture are quite interesting and strange. They make it seem like the bus loop will move more west of the station (or in other words, the east half of the bus loop will be removed). Very odd. Granted the bus flow will significantly drop from what it is now though.
  12. Stage 2 active transportation connectivity for west end stations (Tunney's to Baseline and Moodie). https://ottawa.ca/en/city-hall/public-engagement/projects/stage-2-lrt-station-connectivity-enhancement-study
  13. 4217, 4283, 4453 & 4482 were also retired in May 4218, 4227, 4238, 4256, 4277, 4296, 4302, 4311, 4321, 4334, 4357, 4372, 4374, 4387, 4399, 4402, 4413, 4415, 4418, 4427, 4448, 4454, 4458, 4462, 4470 & 4508 are parked and stored UFN Credit also goes to Enviro_1203.
  14. I'm surprised it's down to a small handful this quickly. The Orion era is coming to an end. I still maintain that OC probably should have gone with ISL engines and Allison transmissions... I'll miss them. By the way, for anyone looking for an update on the Inveros, there were 13 more of them retired this year, in March specifically. All credit goes to user Enviro_1203 on the CPTDB forum. To recap, here's the number of Inveros retired from each batch (this comes from the CPTDB wiki): 4201-4202: only 4202 is active 4203-4273: 4204-4207, 4209, 4211-4216, 4219, 4220, 4223-4225, 4228, 4230-4235, 4237, 4239, 4240, 4243-4246, 4249-4255, 4261, 4263, 4267-4269, 4271 4274-4309: 4276, 4278, 4280, 4285-4287, 4289-4290, 4294, 4300, 4303, 4305, 4307-4309 4310-4439: 4310, 4315-4319, 4325-4328, 4331, 4337-4339, 4344, 4346, 4349, 4352-4354, 4356, 4360, 4363-4365, 4367-4369, 4371, 4373, 4375-4379, 4381, 4382, 4385, 4385, 4388-4390, 4394, 4395, 4414, 4417, 4431, 4434, 4439 4440-4526: 4446, 4450, 4464-4468, 4473, 4475, 4484, 4485, 4488, 4491, 4492, 4494, 4498, 4505, 4512, 4513, 4515, 4517, 4519, 4520, 4522
  15. All great points Shane, one last thing I'd like to add is that rail mass transit is new to Ottawa and it shows. A lot of users get upset or ask questions that are obvious to anyone who's lived in Toronto or Montreal (exemple : why doesn't it run all night?) This makes it even more important to communicate well with customers.
  16. I agree that the communication needs to vastly improve. A recent media article suggests this will be the case when the line reopens this Monday, but time will tell. I'm sure the technical issues are one thing but the fail in communication is what really drives people nuts and increases anger. You could be on a train that is being held, with no idea when it will resume for example. Should I stay on or use surface transit, only to see it leave moments after getting off... or it may stay an hour. There is a reluctance on providing estimates on service restoration but this is essential and most if not all major transit agencies will rail do this. Whether or not it is accurate 100% of the time or not, information is key and helps people make the best decision for them. The other issue that we saw recently was the news on twitter that one trail broke down or was disabled and system-wide holds were in effect. I can understand they don't want to bunch up the trains behind the disabled one as then getting back to normal spacing and intervals between trains will take longer but still, people need to know what is going on. Regardless of what is going on, people NEED TO KNOW when a return to NORMAL is expected. Lets hope that information is much more forthcoming when the line reopens Monday. It's a learning process for all but we need to finally get this right, it's been too long and clearly is one of the major things that is turning people off.
  17. Amazing work taking place. Very impressive the speed at which it is all happening as well. We are fortunate that the location is easily accessible to document and get great photos. Thank you for sharing!

  22. Due to delays and breakdowns especially during winter operations people in Ottawa have become extremely skeptical, negative, upset and angry towards any announcements of maintenance or normal operations slowdown. I can't really blame the average rider but the anger has spread to any announcements. Like you said slowdowns in extreme heat are a normal thing on rail across the world. What I do think would help is if OC transpo had a much better communication instead of just tweets. (A link to of transpo website explaining would help) The speed restrictions from go trains are very well explained. It would have helped a lot if this would be communicated before hand as well
  23. Of a fleet originally around 170, to be potentially down to 30 some left in service is amazing. I never had a problem with those buses. I found them comfortable, spacious and overall a nicer experience than the Inveros. (Quieter).
  24. Loud-Invero has created a Google Sheet to keep track of the remaining Orion VII hybrids https://docs.google.com/spreadsheets/d/1jNPyiZRxn5ItocaaS_QfYjm2-A4vi7zIT3k88IbfzIA/edit#gid=0
  25. Out of curiosity Has anyone spotted any of the new double-deckers on the road yet?
  26. That's right! Knew I forgot something... However, I saw recently that the Baseline portion had been postponed, apparently the public found that the project as presented would result in too much traffic and noise. I'll still add it on the map why not
