So in other words, planning is ongoing, as it is in every other sector, in the face of absolutely unprecedented circumstances. Seems an entirely reasonable position - there is something in place for the next 3 months via EMAs.
I have a feeling the EMA scheme will be in place for at least another year, perhaps amended slightly over time. No chance of any of the franchises being returned to how they were any time soom, renegotiating them all will be a big and lengthy undertaking, and the only other option is to cut services or close lines and stations.
