They all represent a very limited vision for the transit network in Ottawa in the next 20+ years, despite spending a minor fortune. The 'Options': Options #1 and #2 are not even viable since a tunnel operating with the volumes of buses anticipated is not even feasible. 14-16 second headways are unrealistic when station dwell times will exceed that time by a considerable margin, especially if the effective number of stations is reduced (Bay, Kent, Bank, Metcalfe, McKenzie King, Laurier & Campus (7) reduced to Lyon/Kent, Bank, Metcalfe, Union/Rideau & Campus (5)), thus putting more pressure on the remaining stations. Options #3 and #4 might represent a starting point towards an improved network, but as a vision of what the network should look like in 2031 they are inexcusably limited - they are a closer approximation of what it should look like by 2013, not 2031. Therefore, no option is particularly good, with options #3 and #4 "winning" by dint of being less bad. General criticisms and suggestions We should be looking at a network where light rail extends to all four of the extra-Greenbelt suburbs well before 2031. Baseline to Blair is a good starting point, and it is commendable that Transitway conversion is finally on the table as a serious option, if about a decade late. But it's only a starting point. Extending light rail to Bayshore in the west and through the Smyth Road hospital corridor in the east should be the first priority once Blair to Baseline is complete. Many of the bus transitways listed should not be built as such but rather as light rail transitways. For example, there seems to be very little reason to build the Cumberland Transitway as anything other than a light rail transitway. Indeed, there is compelling case to build the Cumberland Transitway as light rail all the way to Trim Rd before converting the East Transitway to Blair since doing so will relieve much of the pressure on the latter and facilitate its conversion. I also notice that many of the secondary or "urban transit" corridors that are part of the current TMP have been reduced to grey arrows denoting "Future Urban Transit" - i.e. post 2031! There is no good reason that most of these corridors couldn't be in service by 2031 and their transit mode should be decided (as in the current TMP) now. In particular, the Carling Avenue and Rideau Street corridors are of concern since they go through downtown, a fact that can influence the decision of whether to go with a tunnel, and, if so, when. Indeed, the entire tunnel question has been treated as a foregone conclusion. Calgary still has plenty of life left in its surface LRT system now that they are lengthening the stations for 4-car trains, and that is for a system that already carries more riders daily than does the Transitway. I don't dispute that we may one day require a tunnel, and it would be prudent and wise (and good planning) to plan for such an eventuality in the immediate future, but whether we need one right away is an altogether different question - a question that was indirectly answered in the section on surface options: > Surface Options ... > An LRT-only option would require: > - Single car LRT operating every 36 seconds (not practical); > - 3 or 4 car trains operating every 1.8 to 2.5 minutes (practical); > and > - 3 to 4 car trains require 90 to 120 metres of platform at > stations. For example, it may well be the case that 3-4 car trains operating on the surface would be sufficient for 15 years and would be available for use much sooner than a tunnel. Of course, that leads to an obvious question: what to do with the surface LRT once a tunnel is in place? There seems to be a one-or-the-other thought process with respect to surface vs subsurface LRT downtown. Well I refer back to my earlier point about the unmentioned "Urban Transit" corridors, particularly Carling-Rideau. This corridor would go downtown but it may not make sense to insert it into a tunnel. It might well make more sense for it to go on the surface downtown. We would then have the genesis of a solution to our tunnel vs surface question: do both but only do each when it makes sense to do so. The implementation could look something like the following: 1. Construct surface LRT from Bayview to Hurdman, and implement diesel light rail extensions south (Leitrim, then Airport and Riverside South), southwest (Barrhaven) and west (Kanata) so as to relieve pressure on the Transitway during conversion while releasing more buses immediately for more frequent suburban feeder service. 2. Convert Transitway from Baseline to Blair, or better yet, Baseline to Bayview and construct Cumberland (light rail) Transitway to Trim Rd. 3. Complete conversion of Transitway from Bayshore to Lincoln Fields, and from Hurdman to Blair 4. Begin planning/design work for the tunnel and for the Carling-Rideau tram line 5. Carry out further extensions of light rail transitway to Kanata, Orleans, Riverside South, etc. 6. Build downtown tunnel and Carling-Rideau tram line 7. Once the tunnel exists, switch Transitway trains into it and the Carling-Rideau tram can use the surface tracks. The interconnections on either side of the tunnel between the two sets of tracks can be left in place for use in emergencies or for periodic tunnel shutdowns, etc. I have plenty of other concerns with the options that have been presented, especially the vehicle costs (based on my knowledge of Calgary's CTrain network, only about $300M of the $1.3B or so set aside for vehicles is needed to buy sufficient light rail vehicles) but even some of the bus transitway costs that have been quoted in the Citizen seem excessive (i.e. $400-500M for the Cumberland Transitway between Blair Station and Trim - how does one manage to spend so much on a practically empty corridor? digging an entire new trench to rival Scott Street perhaps?). I also have concerns with the entire process in that so little has been examined. The options don't even convert the entire Transitway within the Greenbelt, never mind extending light rail across it. There is nothing in the way of phasing or what options are available for immediate implementation. In particular, there has been no discussion or apparent consideration of the use of diesel or other autonomous light rail vehicles on existing tracks to serve people outside the Greenbelt. Citizens have not been asked if the requirement to transfer at Bayview is a reasonable trade-off for having an improved ride for most of the journey and to deliver immediate benefits rather than having nothing much for (apparently) a generation. What of looking into the acquisition of dual-mode vehicles, as recommended by the Mayor's Task Force, once a tunnel is in place? These options or entire areas of discussion have been simply excluded and the result is an unsatisfactory set of limited options to choose from. Regards, -- David P James Ottawa, Ontario
