I think you're referring to the 506 and 511 because of construction
The 506 is still running as a streetcar; Westbound from Main to Bay and Eastbound from University to Main
The route I took for my job shadow was
Starting at Eglinton station,
1) Route 100 to Broadview
2) Subway to Dundas West
3) 504 King Car to Yonge
Walked Up to Queen St and around the area for something to eat
Took the Queen Car to Roncesvale (Dry run to see how far I would need to go to get back to yonge st)
4) From Roncesvale to Jarvis on queen night car
5) Yonge night bus to Sheppard and then to home.
6) I live close to Kennedy Station, a few days later I did an AM rush 506 from Main Station to College Station and that concluded my shadowing.
