Deltic D9009 THUNDERS along the East Coast Mainline on 1Z11 & 1Z13: 06/05/17 

D9009 (55009) hauls the Hull & Leeds Executive tour.
The first shot of D9009 is on a footbridge just outside Peterborough, we see the beast thunder towards London working 1Z11.
Next we see her storm through Peterborough Railway Station heading north on 1Z13. A nostalgic shot indeed...
