The nearest I can think of is Yeovil Pen Mill.
'DMU' is immaterial, so therefore the rest of the clue must be looked at; clue therefore not anagram
Synonyms for 'away' include 'off'
Plymouth has a ferry service to Roscoff
Right of Plymouth on a railway map would be east of Plymouth
Yeovil is east of Plymouth
Yeovil Pen Mill is the station for Yeovil that is further east
SWT now has 'right of way' to run via Yeovil Pen Mill
Probably nowhere near, a bit daft really. Besides, the train might not be completely immaterial; it might have another meaning. And the word 'station' isn't included.
