Toy with rail track (5,3)
I believe the answer is:
train set
'toy with rail track' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for train set that I've seen before include "little loco with this?" , "Number of tracked items" , "model railway" , "Toy with rail track" , "Nitrates (anag) - Hornby product?" .)
