Narrative:
After landing, during rollout the first officer heard a faint pop at 100 KTS, the captain was flying and applied the brakes at 130 KTS and stowed the thrust reversers by 70 KTS with normal light indications, upon turning off the runway at the high taxiway circuit breaker (ZZZ), the captain noticed the #1 engine had over temped at the red line and shut down the engine with the start lever. After parking, the mechanic informed the crew that the #1 engine was still partially in reverse which seemed unusual since there were no indications of a thrust reverser not fully stowed. The crew filed an engine operating report, safety report, and logbook write-up per company policy. The wind on landing was a crosswind 220 degrees at 7 KT and there was no indication of ingestion of foreign objects from the flight deck. The so observed no abnormal indications until runway turnoff when the captain shut down the engine due to overtemp condition. Neither the captain nor so heard the faint pop noise and were not advised until runway turnoff by the first officer when the flight deck workload was reduced. Increased vigilance is absolutely necessary by all crew members during this extremely sensitive transition from reverse thrust to slowing to taxi speed and stowing the thrust reversers.

Title: A B747-200F SHUT DOWN #1 ENG AFTER TURNING OFF THE RWY ON A HIGH SPD TXWY DUE TO ENG EXHAUST GAS TEMP AT RED LINE.
Narrative: AFTER LNDG, DURING ROLLOUT THE FO HEARD A FAINT POP AT 100 KTS, THE CAPT WAS FLYING AND APPLIED THE BRAKES AT 130 KTS AND STOWED THE THRUST REVERSERS BY 70 KTS WITH NORMAL LIGHT INDICATIONS, UPON TURNING OFF THE RWY AT THE HIGH TXWY CB (ZZZ), THE CAPT NOTICED THE #1 ENG HAD OVER TEMPED AT THE RED LINE AND SHUT DOWN THE ENG WITH THE START LEVER. AFTER PARKING, THE MECH INFORMED THE CREW THAT THE #1 ENG WAS STILL PARTIALLY IN REVERSE WHICH SEEMED UNUSUAL SINCE THERE WERE NO INDICATIONS OF A THRUST REVERSER NOT FULLY STOWED. THE CREW FILED AN ENG OPERATING RPT, SAFETY RPT, AND LOGBOOK WRITE-UP PER COMPANY POLICY. THE WIND ON LNDG WAS A XWIND 220 DEGS AT 7 KT AND THERE WAS NO INDICATION OF INGESTION OF FOREIGN OBJECTS FROM THE FLT DECK. THE SO OBSERVED NO ABNORMAL INDICATIONS UNTIL RWY TURNOFF WHEN THE CAPT SHUT DOWN THE ENG DUE TO OVERTEMP CONDITION. NEITHER THE CAPT NOR SO HEARD THE FAINT POP NOISE AND WERE NOT ADVISED UNTIL RWY TURNOFF BY THE FO WHEN THE FLT DECK WORKLOAD WAS REDUCED. INCREASED VIGILANCE IS ABSOLUTELY NECESSARY BY ALL CREW MEMBERS DURING THIS EXTREMELY SENSITIVE TRANSITION FROM REVERSE THRUST TO SLOWING TO TAXI SPD AND STOWING THE THRUST REVERSERS.
