10TC 1700-1701

10TC 1700-1701 were 2017 New Flyer "Xcelsior" XN40s that were introduced with the relaunch of the Purple Line in December 2018. Both buses were painted in a purple livery, they had white LED displays (as with Silver Line buses). They were based out of Royal Street Division and were only for the Purple Line, except in special circumstances. These units were also the first buses in the fleet with white LED displays.

In early March 2019, the Purple Line was suspended. 1701 was pulled from service for repainting- getting a better livery while 1700 remained for regular service. Therefore, the latter unit received exposures for local service so it could operate on other routes while its counterpart was inactive. 1701 returned to Royal Street Division near the end of March for the relaunch of the Purple Line in the Spring Pick.

Upon their return, the two buses sported dedicated branding and received new DC Circulator-inspired decals in a different font. The buses also received new LED headlights to distinguish them from the 1600-series buses. They also had purple seats to match the branding, making them different from the remainder of the Xcelsiors. Towards the end of their lifespan, these units were also joined by 9600, which acted as the backup bus and was specially repainted for the service.

As part of the network change in mid-2019, the Purple Line was discontinued and both units were put in storage as they were not needed for conventional service.
