Boy consumed by train set produced with waterproof material (9)
I believe the answer is:
Here is my best explanation:
'waterproof material' is the definition.
(I've seen this before)
'boy consumed by train set produced' is the subsidiary indication.
I cannot really understand how this works, but
'boy' could be 'paul' and 'paul' is present in the answer.
an anagram of 'train' is 'tarin' which is present in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'with' is the link.
(Other definitions for tarpaulin that I've seen before include "Waterproof cloth", "It provides protection", "waterproof material", "Waterproof sheet", "oilskin hat", "Waterproofed canvas", "sailor's hat", "Canvas", "seaman rarely required" and "Material to waterproof".)
