As people may know this has recently been reliveried and went to the National Railway Museum in York and then on to the greatest gathering a few weeks later and came back but in the gap and most recently it hasn't been in service. Does anyone know what has happened?

Most likely not needed for service yet. They are trying to keep mileage down on certain locos.

Or it could be on maintenance.

They have 12 (I think) 91s for service, but only need 4-5 in use each day, so there is nothing unusual in the loco not being out in traffic.
