People on night train going over these? (8)
I believe the answer is:
sleepers
'people' is the definition.
The answer is an example.
'night train going over these?' is the wordplay.
'night train' becomes 'sleeper' (I've seen this before).
'going over' means one lot of letters go next to another.
'these?' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'sleeper'+'s'='SLEEPERS'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for sleepers that I've seen before include "On which railway lines rest" , "Cross-beams on rail tracks" , "They support the rails" , "Dozers on the train" , "Peerless beams for railway tracks" .)
