RPTR LANDED ON THE WRONG RWY.

Narrative

BEGINNING DSCNT FROM FL370 INTO STL; MONITORED BOTH ATIS FREQS FOR CURRENT WX BUT NEITHER FREQ HAD THE INFO. CARRIER WAVE ONLY. RECEIVED HR-OLD WX FROM CTR INDICATING BASICALLY CLR; EXPECT LDA RWY 12L. NO NOTAMS WERE INCLUDED. APCHING THE FIELD; A VISUAL WAS ACHIEVED AND CLRNC FOR A VISUAL TO RWY 12L WAS RECEIVED FROM TWR. USING LDA/DME IABW (110.1) AS REF; WE MADE LNDG ON THE L RWY. NOT UNTIL TOUCHDOWN DID EITHER PLT REALIZE WE WERE ON RWY 13. LNDG AND TAXI IN WERE UNEVENTFUL. CONTRIBUTING FACTORS: 1) LAST FLT OF THE NIGHT; FATIGUE; COULD HAVE BEEN PRESENT. 2) AT NO TIME WAS THE CREW PROVIDED ANY INFO THAT WOULD HAVE LED THEM TO SUSPECT RWY 12R WAS CLOSED AND ITS LIGHTS OFF. BEING TOLD TO EXPECT THE LDA/DME RWY 12L; NOT THE ILS RWY 12L; REINFORCED OUR IMPRESSION RWY 12R WAS UP AND BEING USED. PRINTED FDC NOTAMS FOR NOV/WED/94 WERE CLEAN FOR MISSOURI. TELECON WITH TWR PERSONNEL AFTER LNDG REVEALED THEY ARE UNABLE TO POSITIVELY ASCERTAIN WHICH RWY ACFT ARE LINED UP ON AT NIGHT AND WERE UNAWARE ATIS WAS NOT FUNCTIONING. POSSIBLE CORRECTIVE ACTION: REDESIGNATE RWY 13/31 AND RWY 12L/30R TO RWY 12L/30R AND RWY 12C/30C RESPECTIVELY.
