'creche' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?

'time to tend to railway' is the wordplay.
'time' becomes 'day' (day is a kind of time).
'to tend to' becomes 'nurse' (I've seen this in another clue).
'railway' becomes 'ry' (abbreviation for railway).
'day'+'nurse'+'ry'='DAY NURSERY'

'and' is the link.

Can you help me to learn more?

(Another definition for day nursery that I've seen is " Kindergarten".)

I've seen this clue in The Daily Express.
