Taking the tortuous little railway out of Holyhead, you can get there (4)
I believe the answer is:
rhyl
'holyhead you can get there' is the definition.
I can't tell whether this defines the answer.
'taking the tortuous little railway' is the wordplay.
'taking' indicates putting letters inside.
'the tortuous' becomes 'hy' (I can't justify this - if you can you should believe this answer much more).
'little' means to remove the last letter (the word is not quite complete).
'railway' becomes 'rly'.
'rly' with its last letter removed is 'rl'.
'hy' going inside 'rl' is 'RHYL'.
'out of' is the link.
Can you help me to learn more?
(Other definitions for rhyl that I've seen before include "Welsh location" , "N Wales resort" , "North Welsh resort" , "Seaside resort in Denbighshire" , "Clwyd resort" .)
