The last vehicle in the formation is Driving Trailer 788, sadly I couldn't get a better shot than this but hopefully I will on my next visit.
Motor Car 458
Driving Trailer 788
Centre Car 798 at Downpatrick this vehicle is being turned into a buffet and on open days is often found at the other end of the line and below is the buffet interior mid way through conversion
Unlike the 80's & 70's the 450's were never split and all 3 vehicles ran together for their entire life.
Above is Motor Card 458 being readied for start up at Downpatrick
