+* A 2-letter stop code (ignore this; it is ambiguous and not needed)
+* An optional "T" indicating terminus (ignore for naming purposes)
+
+Your task is to infer the full station names from the 4-letter codes.
+
+Guidelines:
+
+* Treat the 4-letter code as a compressed version of a real station name (e.g. consonant-heavy, missing vowels, or merged syllables)
+* Use pattern recognition rather than strict decoding
+* Prefer real-world plausibility over perfect letter matching
+* Assume all stations are on the same rail corridor or geographically connected route
+* Use the sequence of stops to inform your guesses (adjacent stations should make sense geographically)
+* If a code is slightly irregular, prioritise what fits the route best over what matches the letters exactly
