Some of the other pairs have stopped running. It's possible that they have been swapped out for service by the other ones that have returned to service like 6244+6246.
Either way, this means that 6244+6246 is not retired nor being used for parts. However, it going to CIY was still likely true, though for maintenance.
Additionally, 6252+6254 has been confirmed to be in 207 St Yard by itself. Now that's interesting...
