Was assigned to 50 engine as a Lt. 1/7/70. Busy, busy, every tour. Believe it was April or May of that year that the 2nd section was established. Each section would be 1st up every other day, number of boxes both sections responded. This cut down on a lot of runs and workers for both engines. Also had interchange, 50-1 with 43 engine. Don't remember exactly but believe interchange was mandated if you had 15 or so runs before 2400 you interchanged for the rest of tour. Or if you did 20 or so runs on the 6x9 you interchanged the next night tour. This also cut down runs/workers.
Was assigned to 82 engine as Captain 9/1/73. They, the admin. did a real job on 82 to keep the numbers down. Went like this-Sq2 would be 1st up for 82 every other night from 1900 to 0100 hours. The nights in-between 82 had mandatory interchange with either 295 or 297 for the entire 6x9. So it would be Monday Sq2 1st up 1900 to 0100, Tuesday interchange with 295 for 6x9, Wednesday Sq2, Thursday interchange with 297 for 6x9, Friday Sq2, Saturday interchange with 295 and Sunday Sq2. This was every day I was there for my 2 1/2 years. I have no idea what the numbers would have been like if 82 had just run 1st up for itself every tour. Even with this on the nights Sq ran for us we did at times 35 runs on the 6x9 as Sq would catch a job and be out most of the tour.
We didn't work 24's then, just straight tours. Every once in a while you did do a 24 for someone who needed their tour off. Remember one in 50 engine did 50 runs for the 24, 25 in the 9x6 and 25 in the 6x9, with a couple of good jobs.
To steal a phrase, was the best of times and the worst of times.
