This engine is owned by Pete Waterman a GWR tank engine, I took it during the autumn steam gala a couple of weeks back, its nick name is big pig & No 6619 the other GWR tank is call'd the small pig
The loco was been check out for the days work ahead, if you look to the right of the engine you can just make out the orange glow from the overalls of the person working.
I do miss the glow of the old lights not quite the same
V2 straightened a bit
Thanks for the info Andy
Maybe worth checking large
