16044, 16775 and 47106(?) the vehicles involved. SC lucky that it was Olympians destroyed and not something newer.
Bus veg upset that something newer was not destroyed
It's 16064 that's been burnt, not 16044
Always had a soft spot for 16064, here's a photo I took of it in happier times at Tiverton Bus Station:
Same thing happened with the "depot" at Biggleswade a few years back - someone threw a cigarette out of their car on the A1 above and somehow a few buses exploded as a result..
