Danforth Line 2 Scarborough Subway Extension

Are you including paving over in the tear down?

8 years if you take the dates from Waterfront Toronto (2016-2024). Arguably the process started before 2016. 2016 is just when city council chose Hybrid Option 3

2 months if you are only interested in the Logan ramp demolition start to end

I’m talking tear down only. If they can tear down that section in 2 months then they can tear out the SRT ROW (Kennedy-Ellesmere) in the same amount of time. Add in tearing out Lawrence East/Ellesmere stations and paving the entire ROW it shouldn’t take more than 6-8 months.

Thats assuming the concrete rail bed can just be paved over and not totally ripped out and rebuilt.

The ROW can be pave over after a sub base is place on top the current base and leaving the pads for the rail under the subbase. Need to remove the power rail to get extra clearance between the 2 lanes. The stations many take longer than 2 months. What are you going to do for the tunnel section???

Sorry bout that. I meant to say for Option2.

Yes Option1 is a whole boatload of work. Maybe Option2 is best with a BRT on Ellesmere or curb lane BRT on Progress similar to Pickering/Ajax
 
They won't work on the Scarborough RT without a large amount of work being done on the line first mainly the small tunnel under the stoville line the curve in is too tight for anything other than the mark 1 trains.
That tunnel been the killer since it was first plan and built. If it wasn't for it, the SRT would had been replace long ago. The one year of rebuilding that tunnel been a killer also along with the cost. The cost would been a drop in the bucket compare to what taking place today.

First look at Metrolinx’s tunnel boring machine used on Scarborough Subway Extension

I suppose you know everything there is to know about the infrastructure hurdles and differences between the 2 sets of trains 👍

It's amazing - there is no way replacing a short tunnel needed to take a year and cost anywhere near the same order of magnitude as the replacement. Kennedy could be solved too, probably for ~30-50m (cost of a new SkyTrain station in Vancouver)

I guess you must know more about it then the TTC does as all of what has been sited comes from a report that they made to find out what it would cost to keep the Scarborough RT as it is but with bigger trains.

This massive TBM should be named “Fat Bastard” in tribute to Scarborough native Mike Myers. The other great names from his Austin Powers movies would be Gold member or Dr Evil.
 
And the RFQ itself.

The Project will include the design, construction, supply, integration and commissioning of the following key elements, among others:
  • three new subway stations, with associated bus terminal facilities;
  • Passenger Pick-Up Drop-Off (“PPUDO”) at the terminal station;
  • eight EEBs and other required emergency and life-safety facilities;
  • design and construction of four Traction Power Sub Stations (“TPSSs”);
  • underground transition structure of approximately 500 metres between Kennedy Station and the tunnel boring machine extraction shaft at Eglinton Avenue East and Midland Avenue;
  • pocket track to be built as an underground structure in the cut and cover section between the extraction shaft and Kennedy;
  • tail/storage tracks and special trackwork, as required;
  • integration with existing infrastructure and systems at Kennedy Station;
  • temporary and permanent roadway modifications and other surface facilities;
  • utility relocations required to facilitate the construction of the stations, rails, and systems;
  • all systems equipment including track, ventilation, signals, communications, integrated control system, traction power, and all other permanent mechanical and electrical systems;
  • communications systems including network, public address, radio, telephone, Wi-Fi, CCTV, passenger information systems and supervisory control and data acquisition (“SCADA”) for controls and indications to TTC Control Center;
  • conduit/raceway and cabling work for new rail systems, new facilities and interconnection to existing TTC systems;
  • safety & security systems including intrusion detection and emergency stop;
  • fare collection and enforcement equipment compatible and integrated with the Sponsor’s fare collection software system (“PRESTO”);
  • supply, installation and integration of fixed block signalling, and provisions for Automatic Train Control (“ATC”);
  • provisions for platform edge doors; and
provisions to enable TOC works, which may include overbuild protection, accounting for adjacent loads, mechanical systems interface.
 
3 stations only is a joke. Are they at least considering roughing in some others for future demand?

It would be good to add a station at Brimley and Eglinton, that spot can have quite a bit of local density.

Other than that, the spacing is consistent with other outer sections. Wilson to Sheppard West, Eglinton to Sheppard on Line 1, Yonge to Bayview and Leslies to Don Mills on Line 4. Not ideal, but nothing exceptional.

The one-stop plan, Kennedy to STC with no stations in between, would be a joke indeed.

I’d take one stop from Kipling to square one without complaints. Who knew divas came from Scarborough.
