mc5 - Riddle-me-ree Crescent

Collective consciousness riddle-making. The answer must be a London Underground station name.

My last is in CONSONANT never in VOWEL
If you can't guess this main line, just throw in the towel.

My first's in OUTRAGEOUS but not found in STAID

My second's prolific in MILKING and MAID

My third hides in BRACKEN but stays out of GORSE

My fourth's in the ALPHABET somewhere, of course!
