Where to find train lines carrying eastern rulers, say (10)
I believe the answer is:
stationery
'rulers say' is the definition.
(I know that ruler is a type of stationery)
'where to find train lines carrying eastern' is the wordplay.
I cannot really understand how this works, but
'lines' could be 'ry' (abbreviation for railway) and 'ry' is found within the answer.
'eastern' could be 'e' and 'e' is found in the answer.
The remaining letters 'station' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for stationery that I've seen before include "Treasury tags, for instance" , "Materials needed for writing" , "The papers, etc" , "Various items in paper" , "Pens, pencils, paper etc" .)
