GBRf 66747 (leased from Beacon Rail Leasing) has been released from Eastleigh Works, where it received a repaint from grey into the current GB Railfreight livery. An image of the loco in fresh paint can be found here: link. This leaves 66748 as the only grey Class 66 locomotive in GBRf's fleet. Note that 66747 received Beacon Rail Leasing logos on its sides, similar to 66749.
