Can You See The Wood For The Trees?

[itinerants]

Completely stumped by numbers 59 and 90 if anyone can help with a clue or two.
90 ....so the horse no longer amuses people (8)
59 Boy smashed an avenue of trees at the scene of a tragedy on track (8,5)

Bibster I was thinking the same, hunting for a race course but now I've done it and it's turned out to be the location of a rail disaster.
Think word for young boy (3), followed by smashed (broke) then another word for an avenue of trees. UK tragedy.
