From CPTDB. There were 50 ALRVs. Only 8 remain in serviceable shape. There were 200 CLRVs. 89 have been retired. 42 + 89 = 131. There is not even a net increase in vehicles. Just bigger and newer.126 on the roads now but they still can't run any on either the 505 or 506.
As for 505. There is a lot of construction on Dundas still between Spadina and Yonge. Streetcars would be hopeless there.
But even with half the 504s turning at Cherry loop, Broadview is tied up regularly at Danforth.
I am not sure that 505 will be a streetcar again for some time. I believe that Dundas West and Broadview can’t handle the larger cars. Each needs a third platform notwithstanding deflecting a large number of car movements to Cherry and Dufferin loops.
