In my April 23rd post in this thread I showed how it would be possible to get CP on a 1% gradient making it easier to sell to them and to reduce energy consumption on the line (which in the case of diesel means revving up the engine to climb slopes and increasing exhaust).
This plan eliminates all grades over 1%, eliminates most of the underpasses, and keeps all the streets open.
STEP 4 – WESTON Construct the line north of the Humber river as planned. The Georgetown line would pass over Weston Rd at 138m, this would depress Weston Rd by 1.5m. The CP line would pass under Oak St at 128m (after having passed under an elevated Wilson bridge and under the 401 lower than currently done) and follow a 0.3% grade down to meet the Georgetown line at Church St Weston. The corridor would pass under Church St Weston at 125m which is a 1.4% gradient from Weston Rd which allows the Church St Weston bridge to pass over at ground level. Pass under King St Weston at 123m (a 0.7% gradient from Church St Weston) to allow the King St Weston bridge to pass over at ground level. Pass under John St Weston at 122m (a 0.5% grade from King St Weston) allowing John St Weston to remain open and pass over on a bridge at ground level. Pass under Lawrence at 121m (a 0.5% grade from John St Weston) allowing the Lawrence bridge to pass overhead at ground level eliminating the dingy Lawrence underpass. Pass under Dennison Rd at 117m (0.5% grade from Lawrence) allowing the homes on Denison to be saved, no dingy underpass to be built, and a bridge to cross at ground level. Pass under the existing Jane St bridge at 118m (a 0.2% upward grade from Dennison). Pass under Ray at 118m allowing the Ray bridge to pass over at less than 1m above ground level eliminating the dark Ray St underpass. Finally pass over Eglinton at 123m (a 1% grade upwards) on the existing Eglinton underpass due to the proximity of Black Creek. Construct the Eglinton West GO Station to connect with the Eglinton LRT. Install electrification on this whole segment from Pearson to Black Creek but leave it inactive.
This plan eliminates all grades over 1%, eliminates most of the underpasses, and keeps all the streets open.
