Well, yes it was me on that train....Good Old Flying Scotsman......
Arrived at Taunton, changing ends I noticed a burning smell, with flames coming out between coaches A (TGS) & Coach B.
Informed the signalman, to get line blocked and shut down both engines...electrical fire then becomes a normal fire...used AFFF fire extinguisher and put the fire out myself.
I removed the jumper cable, which was badly scorched and placed it it the rear cab...
Fire brigade turn up and see that I have put the fire out but they decide to use a CO2 on it themselves...guess what?

?
THEIR FIRE EXTINGUISHER WAS EMPTY!!!!!!!!!! then a few more firemen turned up with a working fire extinguisher.
After fitter checked the train, I went empty to the MARSH Depot...end of incident.....
No passengers on board as train was 5A08 but returned to Bristol as 5Z74..........
SO LESSON TO BE LEARNED......Never believe everything you read in a paper......
