Place for records about central point on railway (8)
I believe the answer is:
registry
'place for records' is the definition.
(I've seen this before)
'about central point on railway' is the wordplay.
'about' becomes 're' (regarding**).
'central point' becomes 'gist' (I've seen this before).
'on' is a charade indicator (letters next to each other).
'railway' becomes 'ry' (abbreviation for railway).
're'+'gist'+'ry'='REGISTRY'
(Other definitions for registry that I've seen before include "Office where records are kept" , "Place where written documents or records are kept" , "where files may be observed" , "Official written record of names, events etc" , "Place to keep records" .)
