Narrative:

We were on a scheduled run from mem to crw. The forecast conditions for crw at our scheduled time of landing was 3 mi in fog. However, according to the ATIS, they were 0 in fog. RVR for 23 was 400, variable 6000, we require 2400 for landing. At approximately 78 mi from crw our right gear box low oil pressure light flashed on, then off. The light stayed off for a few moments then flashed again. Over a period of approximately 5-7 mins the flashing increased in frequency and in length. All other engine parameters were normal. At the point when the light was staying on for about the same amount of time as it was off, I elected to shutdown the right engine. I took over the controls and had the first officer go through the emergency checklist items for an engine failure. The closest airport was hts, but they were 1/8 in fog. Not wanting to perform a mins approach at crw on 1 engine, I elected to divert to bkw which was 55 mi away, and they were clear with 12 mi visibility. We contacted company via flight telephone then advised ATC of our intentions. Since it was a precautionary shutdown we did not declare an emergency. We then made a normal landing at bkw.

Title: ACR MDT ON NIGHT FREIGHT FLT INFLT ENG SHUTDOWN AND DIVERSION TO ALTERNATE ACCOUNT DEST WX.

Narrative: WE WERE ON A SCHEDULED RUN FROM MEM TO CRW. THE FORECAST CONDITIONS FOR CRW AT OUR SCHEDULED TIME OF LNDG WAS 3 MI IN FOG. HOWEVER, ACCORDING TO THE ATIS, THEY WERE 0 IN FOG. RVR FOR 23 WAS 400, VARIABLE 6000, WE REQUIRE 2400 FOR LNDG. AT APPROX 78 MI FROM CRW OUR R GEAR BOX LOW OIL PRESSURE LIGHT FLASHED ON, THEN OFF. THE LIGHT STAYED OFF FOR A FEW MOMENTS THEN FLASHED AGAIN. OVER A PERIOD OF APPROX 5-7 MINS THE FLASHING INCREASED IN FREQ AND IN LENGTH. ALL OTHER ENG PARAMETERS WERE NORMAL. AT THE POINT WHEN THE LIGHT WAS STAYING ON FOR ABOUT THE SAME AMOUNT OF TIME AS IT WAS OFF, I ELECTED TO SHUTDOWN THE R ENG. I TOOK OVER THE CTLS AND HAD THE FO GO THROUGH THE EMER CHKLIST ITEMS FOR AN ENG FAILURE. THE CLOSEST ARPT WAS HTS, BUT THEY WERE 1/8 IN FOG. NOT WANTING TO PERFORM A MINS APCH AT CRW ON 1 ENG, I ELECTED TO DIVERT TO BKW WHICH WAS 55 MI AWAY, AND THEY WERE CLR WITH 12 MI VISIBILITY. WE CONTACTED COMPANY VIA FLT TELEPHONE THEN ADVISED ATC OF OUR INTENTIONS. SINCE IT WAS A PRECAUTIONARY SHUTDOWN WE DID NOT DECLARE AN EMER. WE THEN MADE A NORMAL LNDG AT BKW.
