There are lots and lots of tasks that the CSAs will be doing that the operators will be not. For one, they need to know the layout of every stop and station top to bottom. They need to know where supplies can be found in a pinch. Where the water taps are located. Escalator and elevator switches. The list goes on.
Now yes, there are fewer of them on the Finch West line, and their tasks will be somewhat minimal in many cases considering that most of the stops are quite simple shelters and platforms. But they still need their training to know where everything is, and how to access it, and they need to be around to perform their tasks. In a way, the RSD is the final stage of their training, as they may have gotten some quick on-site and classroom training earlier, but have not needed to use those skills until now.
The operators have been running various stress tests on Finch West, but they haven't yet started the RSD. The hope is that will start soon, although no date has been announced as yet.
Similar bags filled with water, usually.
