I'm a little stuck... Click here to teach me more about this clue!

'where some have crashed when travelling?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'long wait around' is the wordplay.
'around' indicates anagramming the letters.
'long'+'wait'='longwait'
'longwait' anagrammed gives 'WAGON-LIT'.

Can you help me to learn more?

(Other definitions for wagon-lit that I've seen before include "Sleeping car on continental trains" , "sleeper" , "In-law got injured in sleeping car" , "Continental sleeping-car" .)
