US railway to accommodate inn (9)

I believe the answer is:

roadhouse

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

'inn' is the definition.
(I know that roadhouse is a type of inn)

'us railway to accommodate' is the wordplay.
'us railway' becomes 'road' (I can't explain this - if you can you should believe this answer much more).
'to accommodate' becomes 'house' (I've seen this before).
'road'+'house'='ROADHOUSE'

Can you help me to learn more?

(Other definitions for roadhouse that I've seen before include "Country inn" , "place of refreshment" , "pub, by the way" , "accommodation" .)

I've seen this clue in the Sydney Morning Herald.
