The thing i was trying to do on mine was to simplify the transit lines as opposed to deasine's idea where the M-Line remains a sort of cut off figure 8. M-line would be strictly east-west, expo would be north-south to surrey, canada line north-south to richmond and the ring line would allow anyone from Burnaby, Port Moody, and Coquitlam a one seat ride downtown.

That was the following communities would have no transfer service to downtown

Burnaby
Surrey
East Vancouver
Mid Vancouver (Cambie area)
New West
Richmond

Communities with one transfer service to DT

Port Moody (M-Line->Ring Line)
Coquitlam (M-Line->Ring Line)
Westside Vancouver (Bus->Canada or Expo)

I decided to make the ring line connect with the M-Line at brentwood because the tracks could easily be spurred between brentwood and gilmore. It would be nice to have direct SkyTrain to SFU so i'm going to work on a map with the Ring Line passing there, all the while changing the M-line to east-west only. there really would be no need to continue M-Line downtown as that would cause 3 different SkyTrain lines to share one stretch of track going downtown, which could be a bit confusing. This way the only time two lines share track is due to Ring Line. Also I guess frequencies could be increased to 90 seconds for each line's trains for a combined frequency of 45 seconds on shared portions during peak hours, though it wouldn't probably be needed as Burnaby, Port Moody and Coquitlam residents would have the Ring Line to go DT and not need to use the Expo line, thus freeing up alot of space on those trains.
