Work Schedules and Sleep Patterns of Train and Engine Service Employees

Survey of Work Schedules and Sleep Patterns of
Train and Engine Service Employees
**Important: Please Read Before Making Entries in Daily Log**
Using the Daily Log

The log is divided into 14 sections. Start a new section for each
new day. On the section divider page, write the date. Please start
with Day 1. Begin your log on a day that you will be working. It
is important that you provide data for 14 consecutive days. If
you have scheduled a vacation during this 14-day period, do not
begin the log until after the vacation.
Complete the log for every day of the study, not just the days that
you work. We need a record of your sleep for all 14 days.
Try to make entries in the log upon arising and at the start and end
of each work period. If for any reason you do not record data at
the appointed time, fill out your log as soon as possible to the best
of your ability. The study results will not be meaningful without
complete log book entries from you.
Draw a vertical line in the appropriate column for the time period
of each activity or sleep period and write the start and end times
next to the line.
The log contains a sample entry for 2 days. Please review this
example to make sure that you understand how to make entries in
the log.

Sleep Periods
(complete daily)

Record your main sleep periods as well as any supplementary sleep
periods or naps. Enter sleep quality ratings for your longest sleep
period ending on each day. If your sleep is interrupted due to
family or other circumstance for more than 15 minutes, please
record this on the log by showing two separate sleep periods.
Record interruptions of less than 15 minutes as continuous sleep.
Next to the vertical line in the sleep column of the activity page,
write an “A” to indicate that you slept away from home or “H” to
indicate that you slept at home.
Explain anything unusual about your sleep in the Comments
section.

Work Periods

Make entries on the activity page to record your travel to/from
your reporting point (Commute), your work period (Work), and
limbo time, if any. Record as commute, the period from leaving
home or lodging until you arrived at your reporting location.
If you start a work period today that will end tomorrow, rate your
alertness today when you mark up and tomorrow when you mark
off.
Explain anything unusual about your work period in the
Comments section.
