Yep, it has the fire extinguisher modification in it (like the Wrexham branded 67s do too) so it can be driven from the DVT without need for a competent person to stay inside the loco while the train is in service.
It had been at Wembley all of last week. I wondered if they were going to attach it to a passenger service any time soon, as the locos are rotated between diagrams fairly often.
