Train fare? (5-2-6)
I believe the answer is:
meals-on-wheels
'train fare?' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'train fare?' is the wordplay.
I cannot quite see how this works, but
'train' could be 'el' (El train, short for elevated railway) and 'el' is found within the answer.
'fare?' could be 'meals' (I've seen this in another clue) and 'meals' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Another definition for meals-on-wheels that I've seen is " Women see halls (anag) -- welfare service".)
