Here is the latest version of my proposed beltline subway for Toronto - Same idea; new graphic

This version shows existing subway lines, new lines and extensions and new extensions in progress, and my proposed new lines

NOTE: I am not taking credit for most of my proposed new lines; most are obvious or have already been proposed by others

I revised my plan for an elevated rapid transit line serving Toronto, Mississauga, Brampton, and Durham Region (MBTD Monorail or HERT) to an LRT, but; I was not satisfied that an LRT will do the job, so in order to cover the distances and achieve the speeds I feel will be required, I made the line an Express LRT with limited stops instead – The line will have at least one stop in each community and connect with every major rapid transit line along its route - I am calling it MBTD Express LRT

The first phases of the route will be a Scarborough-Pickering/Ajax line, and a Mississauga-Pearson Airport line

The Scarborough-Pickering/Ajax line (First phase of a Scarborough-Durham line) line will interconnect with the following:
- Lawrence GO/SmartTrack
- McCowan Road (Scarborough) Subway
- Markham Road LRT
- Crosstown East LRT
- Sheppard LRT or BRT

The Scarborough-Pickering/Ajax line will be extended to form the Scarborough-Durham line – This next phase of the line will interconnect with Pickering GO and have the following stops:
- Pickering GO
- Pickering Centre
- (Possibly) Pickering East
- Ajax Centre
- Whitby Centre
- Oshawa West
- Oshawa Centre
- Oshawa East
The line can eventually be extended east to Clarington/Bowmanville

The Mississauga-Pearson Airport line (First phase of a Mississauga-Toronto line) line will interconnect with the following:
- Meadowvale GO
- Hurontario LRT
- Pearson Airport, UP Express, and SmartTrack LRT

The Brampton-Pearson Airport line will have its terminus and a large parking facility at Dixie and Mayfield Roads, and interconnect with the following:
- Brampton Züm BRT at three stops along Dixie Road
- The Mississauga line, UP Express, and SmartTrack LRT, at Toronto Pearson Airport

The Mississauga and Brampton lines will eventually be extended east to interconnect with:
- Weston GO
- Jane LRT or Beltline Subway
- Toronto-York Spadina Subway
- Yonge Street Subway
- Don Mills (Relief Line) Subway, and;
- The Scarborough-Durham line at Lawrence GO/SmartTrack

The Mississauga line can eventually be extended west to Milton

Hi All - I revised my plan for an elevated rapid transit line serving Toronto, Mississauga, Brampton, and Durham Region to an LRT (MBTD LRT), but; I was not satisfied that an LRT will do the job, so I have decided to make it an Express LRT with limited stops instead – The line will have at least one stop in each community and connect with every major rapid transit line along its route - This will increase the average speed significantly and should be enough to accommodate the distances required - I am calling it MBTD Express LRT

The first phases of the lines will interconnect with the following:
- Meadowvale GO
- Hurontario LRT
- Brampton Züm BRT (3)
- Pearson Airport, UP Express, and SmartTrack LRT
- Weston GO
- Jane LRT or Beltline Subway
- Toronto-York Spadina Subway
- Yonge Street Subway
- Don Mills (Relief Line) Subway
- Lawrence GO/SmartTrack
- McCowan Road (Scarborough) Subway
- Markham Road LRT
- Crosstown East LRT
- Sheppard LRT or BRT
- Pickering GO

The line can eventually be extended east to Oshawa and Clarington/Bowmanville, and west to Milton
