Could be Mike, I just don't know. We had one of the #51's that were set out for a FLT roll into the pit cab end first at McDoel one evening. They put the wrecker on the turntable, picked the engine up, and turned the table till it lined up, then set the engine back down. No cribbing or anything, and it only took about thirty minutes. It puctured the fuel tank though, and they had a mess to clean up.
The hostler set the two units out from the north end, then cut the brakes out on the north unit and didn't cut them back in on the south end, which was the lead unit for the FLT. The brakes leaked off, and since the track in front of the yard office was downhill toward the table, they rolled away. The helper had earlier turned the table, so they just went in the pit.
I was working the yard job, and was in the yard office when Beener Stewart registered out on the FLT. He went out to get on the engines, then came back in and told the yardmaster "I can't take those engines". When the yardmaster asked him why, he said "because they're in the turntable pit".
