Maybe there would be a wye out in the yard someplace, buts most steam locomotive engine servicing facilities did NOT have a wye in addition to the turntable. Also, having a Hosteler and Helper taking a locomotive out of the terminal to a wye someplace "out in the yard", would have taken a Hosteler crew away from the normal duties within the terminal, for probably well over an hour.
Maybe so, but what other options are there? Run backwards. An hour or more to turn on the wye is a little much.
20 minutes tops.
If it actually takes 20 minutes to accomplish the task, is that assuming all equipment and laborers are staged and ready? You can probably more than double that time if equipment and laborers have to stop what they are doing and regroup. And I would doubt they would be idle and awaiting the assignment.
I have provided statistical analysis for "wrench time" studies for maintenance crews of various industries for a friend of mine who does maintenance planning and scheduling consulting around the world. A "wrench time" of 30% to 40% is pretty well standard. That is, if the crew worked 10 hours a day, they would actually be working at the job site for only 3 or 4 hours.
I am an outage manager for a power plant. I totally agree with the total time of task assessment as you have it laid out.
