The schedule is CLRV, but equipment swaps will be done if there's a new streetcar available. This is consistent with how conversion was done on Spadina -- CLRVs were scheduled and new streetcars substituted 1-for-1 as they were made available.
Currently, only 510 and 509 are officially scheduled for new streetcars. Due to the lead time required for scheduling, the 509 one was prematurely changed to new streetcars based on an earlier iteration of the delivery schedule. With 510, ALRVs were substituted when new cars weren't available; on 509, CLRVs. Once there are enough vehicles on site to consistently operate 514 with new cars, along with 509/510, the 514 schedule will then be revised.
