Bank Robbery
Bank station has recenty finished phase 1 of its upgrade project. Phase 2 is soon to follow, starting in February or March, with further phases after that.
The station has had additional CSAs to ensure that the extra work generated by the project can be carried out. So you might think that those CSAs should stay on the station for phase 2. But management have a different idea - boot them out and let the SRT do the work instead.
