sidings

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

'resting track runners' is the definition.
I can't tell whether this definition defines the answer.

'signs i'd put out' is the wordplay.
'put out' indicates an anagram.
'signs'+'id'='signsid'
'signsid' with letters rearranged gives 'SIDINGS'.

'for' is the link.

Can you help me to learn more?

(Another definition for sidings that I've seen is " railway stores".)

I've seen this clue in The Globe and Mail.
