Narrative:
At or near top of descent; #1 engine generator drive oil temperature light came on with temperature gauge showing full scale deflection in the high range. Irregular procedure was accomplished with #1 CSD disconnected and loss of generator #1. Aircraft was dispatched with APU inoperative so we were down to 1 generator (#2) going into ZZZ night IFR to ensure expeditious handling by ATC (procedure instructs landing at nearest suitable airport) we declared an emergency and flew an ILS approach to runway at ZZZ without further incident.

Title: B737-500 FLT CREW HAS A #1 CSD OIL TEMP LIGHT; DISCONNECTS CSD; DECLARES EMER AND LANDS.
Narrative: AT OR NEAR TOP OF DSCNT; #1 ENG GENERATOR DRIVE OIL TEMP LIGHT CAME ON WITH TEMP GAUGE SHOWING FULL SCALE DEFLECTION IN THE HIGH RANGE. IRREGULAR PROC WAS ACCOMPLISHED WITH #1 CSD DISCONNECTED AND LOSS OF GENERATOR #1. ACFT WAS DISPATCHED WITH APU INOP SO WE WERE DOWN TO 1 GENERATOR (#2) GOING INTO ZZZ NIGHT IFR TO ENSURE EXPEDITIOUS HANDLING BY ATC (PROC INSTRUCTS LNDG AT NEAREST SUITABLE ARPT) WE DECLARED AN EMER AND FLEW AN ILS APCH TO RWY AT ZZZ WITHOUT FURTHER INCIDENT.
