Although I remember seeing Warships on the mainline, that was long before I had a camera. So here is my first picture of one on the mainline! D821 (minus its Greyhound nameplates) passes Oaksey on 4 September 2017 in the middle of the 0Z50 11:50 Old Oak Common to Kidderminster loco convoy, hauled by D407 Hercules. Note the temporary through piping for the train air brakes.
