This document was originally written as a Technical Memorandum for internal use by FRA in 

2001. A substantial amount of research has been undertaken in the dozen years since this 

memorandum was produced, including a series of diary studies that provides details about when 

signalmen, maintenance of way employees, locomotive engineers and conductors, and 

dispatchers work and sleep (for a summary see Fatigue Status of the U.S. Railroad Industry 

http://www.fra.dot.gov/eLib/details/L04320). By contrast, this memorandum examines 39 

examples of nominal work schedules for locomotive engineers and conductors in passenger 

service, which may be of interest to researchers who are evaluating and analyzing work 

schedules and fatigue. In the interest of promoting further research, FRA makes this 

memorandum available to the public.

1 Introduction

1.1 Background 

The railroad industry is characterized by continuous operation, 24 hours a day, 7 days a week. 

This type of industry requires workers to perform their jobs at all hours of the day and night, 

many times on an irregular schedule. The Hours of Service Act, passed by Congress in 1906 and 

amended as recently as 1969, limits the maximum hours on duty for all railroad employees 

involved in the movement of trains.1 The Act also prescribes a corresponding minimum rest 

period per 24-hour interval. However, these regulations do not account for the cumulative 

fatigue resulting from successive days of night work, an irregular schedule, or the timing of a rest 

period.

The underlying problem with night work, or any schedule that requires an individual to be awake 

when he or she would normally be sleeping, is that it requires the individual to override their 

circadian clock, which pre-programs humans for daytime activity and nighttime sleep. If a 

worker’s schedule requires the night shift consistently, some adaptation may occur due to the 

adjusted work-rest pattern. However, this adjustment is difficult due to the biological cues of the 

night-day cycle and our predominantly daytime-oriented society. In addition, shift workers tend 

to revert to a normal day schedule on their non-work days, thus limiting their physiological 

adaptation to working nights.

Previous research has consistently shown that employees with irregular work schedules and/or 

night shifts report higher levels of fatigue and poorer sleep patterns than those working a regular 

day or evening shift. The night shift is especially problematic because, in addition to the 

circadian disruption stated above, the period between 0300 and 0500 is a low point for body 

temperature, performance, and alertness. During this time workers are more prone to 

distractions, lack of focus, poor memory, bad mood, and slow reaction times. Individuals 

performing safety critical jobs at this time must take precautions to counteract the feelings of 

sleepiness that are likely to occur and thus minimize the risk of an accident and personal injury.

In 1997, Amtrak began operating several of its overnight runs with one engineer rather than the 

traditional two-person crew in the locomotive cab. Following an accident in 2001 on a train with 

a one-person operation, the Federal Railroad Administration (FRA) suspended this practice 

pending an examination of the safety risks. This analysis was conducted to provide FRA with 

information for use in assessing the nominal work schedules of Amtrak locomotive engineers 

required to work between 1200 and 0600.

1.2 Objectives

The overall objective of this work was to generate data regarding the characteristics of Amtrak’s 

1200 to 0600 locomotive engineer runs. Below are the specific tasks involved in accomplishing 

the work:

1. Formalize a methodology for analysis of the schedules.

2. Aid in the collection of nominal work schedules for the 39 affected jobs across eight 

divisions.

3. Characterize the schedules in terms of weekly job starts, work patterns, and start time 

variability.

Industry http://www.fra.dot.gov/eLib/details/L04320, section 1.1 for an update.

4. Organize the database to enable a more rigorous analysis planned by the government to 

develop fatigue indices.

1.3 Fatigue and Shiftwork Terminology

The analysis and discussion of the Amtrak engineer work schedules make use of specialized 

terminology for describing and analyzing fatigue and shiftwork issues. The following 

terminology is relevant to the present study: 

Actual schedule – Actual hours worked, which may differ from the nominal schedule due to 

overtime, days off, or re-assignments.

Circadian rhythm – A self-sustained biological rhythm in which an organism’s natural 

environment is normally synchronized to a 24-hour period.

Clockwise or forward shift rotation – A work schedule in which the shifts move forward, from 

day to evening to night.

Counterclockwise or backward shift rotation – A work schedule in which the shifts move 

backward from night to evening to day.

Double shift – Two consecutive shifts worked in one 24-hour period.

Duty cycle – Time between the start of consecutive work periods or shifts.

Fast rotation – A work schedule in which shift rotations occur from day to day.

Fixed shift – A work schedule in which the hours of work remain the same from day to day.

Irregular shift – A work schedule that is variable and erratic.

Job – The planned hours of work for each day of the week.

Nominal schedule – Scheduled on-duty and off-duty times. Since extraboard personnel do not 

work a regular assigned schedule, these individuals do not have nominal schedules.

Off time – The hours that an individual is not normally required to be on duty.

Rotating shift – Work in which the hours change regularly.

Shift – Time on a given day that an individual is scheduled to be on duty. One of the work 

periods that make up a job.

Shiftwork – Any non-standard schedule in which most of the work hours are outside the period 8 

a.m. to 4 p.m.

Split shift – A schedule of full-time work in which a period of work is followed by a break and 

then another period of work.

Work cycle – The number of days in the repeating pattern of scheduled work periods.

2 Work Schedule Characteristics

The characterization of the Amtrak locomotive engineer schedules involved a variety of 

graphical and analytical methods. This section begins with a description of the process for 

developing these work schedules and then describes the raw work schedule data. An explanation 

of the various metrics used to characterize the schedules follows, along with the results.

2.1 Development of Engineer Schedules

Twice a year, in the spring and fall when Daylight Savings Time changes occur, Amtrak adjusts 

its train schedules to accommodate anticipated changes in ridership. These schedule 

requirements determine the times when engineers are needed to operate Amtrak’s services. With 

the exception of the Northeast Corridor, most Amtrak corridors have only one or two trains a day 

so there are limited options for scheduling crews.

Development of individual jobs to cover the required service is more of an art than an exact

science for Amtrak. Each Corridor Service Manager is responsible for defining the jobs for his

or her corridor. The local union chairman may also be consulted. The train schedule, existing 

crew bases, and union agreements, as well as Hours of Service requirements, all constrain the 

Service Manager’s options. In recent years, Amtrak has also attempted to incorporate ergonomic 

principles into this process.

Twice a year the Service Manager reviews the existing jobs and makes adjustments to them. 

Most likely, he or she will do this in consultation with the local union chairman. Then the jobs 

are posted for competitive bidding on a seniority basis.

2.2 Description

Amtrak provided data for review in the form of nominal schedules current as of June 28, 2000. 

The nominal schedule indicates the days and hours of each work or on-duty period. Actual hours 

worked by each job incumbent were not provided. The work cycle for each of these jobs is 1 

week. This means that the job incumbent repeats the same series of work periods every week. 

Many locomotive engineers jobs have fixed shifts where the same hours are worked on each 

work day. The remaining jobs have irregular shifts. 

All of the data was coded and entered into an Excel spreadsheet for analysis. The data for 39 

different jobs from 7 divisions is presented in spreadsheet format in Appendix A. Each job and 

its associated work periods were entered as a separate row. Columns of the spreadsheet contain 

the following:

• Job ID as assigned by Amtrak.

• Day, start, and end time of each run or work period.

• Length of the work period.

• Time off between the end of the prior work period and the start of the current work 

period.

• Duty cycle, defined as time between the beginning of the prior work period and the start 

of the current work period. 
4

2.4 Shift Assignments

Each work period was classified into one of three shifts based on when it occurred during the 

day. First, second, and third shifts are usually considered eight hours in length with at least 

seven consecutive hours within core shift hours. Core hours for different shifts are shown in 

Table 1.

Table 1. Typical Core hours

Shift Core Hours

1 0600 1600

2 1500 0100

3 2200 0700

The Amtrak locomotive engineer runs cannot be readily classified as typical shifts. The average 

run duration for the Amtrak engineers is less than 6 hours. Most of the runs do not have the 

required core hours for standard shift classification because their start and stop times span two of 

the above shift definitions. In these instances, the work period was assigned to the shift having 

the majority of the hours. In addition to the general core shift hours, if a job involved being on 

duty at 0400, the job was considered a third shift job. This hour is of particular concern because 

human alertness tends to be at a minimum at around 0400. The left-hand portion of Table 2 

describes each job in terms of the various days and shifts that comprise the job. A “0” indicates 

that the job does not work for the day. This table provides a shorthand representation of each job 

and the work periods that make up each job.

2.5 Work Periods

One important characteristic of a job is the pattern of work periods over the course of the week. 

The right-hand portion of Table 2 provides summary statistics for each of the jobs and each 

division. This group of engineer jobs has between two and eight work periods per week. The 

average number of work periods or job starts per division ranges from 4.5 to 8 per week. All but 

6 of the 39 jobs involve multiple job starts within 1 day (midnight to midnight). Fifteen jobs are 

comprised entirely of work days with multiple job starts. (Multiple job starts refers to days when 

the engineer has two distinct work periods separated by a break of several hours. This is not 

referred to as a split shift because the second work period does not necessarily involve a repeat 

of the work done in the first work period.) All but the San Antonio (SAS) jobs require fast 

backward rotation.

All but three of the jobs involve a night shift, as defined in section 2.3. Only the jobs in the 

Buffalo (BUF) division have night shifts occurring on consecutive days.

2.6 Work Patterns

Table 3 contains summary statistics with regard to work patterns for each job, each division, and 

the entire group of 39 jobs. The average shift length for the group of 39 jobs is 5 hours 59 

minutes with a minimum of 3 hours 8 minutes and a maximum of 10 hours and 16 minutes. The 

range in shift length across divisions is an average of 4 hours 26 minutes for the BUF division 

and 7 hours 56 minutes for SAS.

Summary statistics for time off and duty cycle are also presented in Table 3. For this group of 

jobs the average length of the off-duty period (time between the end of one shift and the start of 

the next) over the 1-week work cycle is 1 day. However, the time off for these schedules ranges 

from 50 minutes to 5 days 20 hours. If Job XFCW-52, which consists of only two work periods 

on Sunday, is not considered, then the maximum off-duty period is 3.5 days. The jobs in the 

BUF division have the shortest average off-duty periods and average 17 hours. Nearly all of the 

jobs provide 2 consecutive days off (see Table 2).

With regard to duty cycle (time between consecutive shift starts), the average is 1 day 10 hours. 

Excluding Job XFCW-52, the range in off-duty time is from 4 hours 45 minutes to 3 days 17 

hours. The SAS division has the longest duty cycle with an average of 2 days 3 hours. All of the 

other divisions have significantly shorter average duty cycles.

To facilitate comparison of jobs within a division, the average shift length for each job was 

converted to a standardized score (Z-score). The Z-score for the ith job is computed from the 

following:

( )

∑( ) =

−

− = N

i

i

i

i

x X N

x X Z

1

2

/

where

X = arithmetic average of shift length for a group of N jobs

i x = average shift length for the ith job

This transformation produces a distribution of values with an average of zero, where zero 

represents the mean shift length for the division. The values between +1.0 and –1.0 indicate an 

average shift length that is within one standard deviation for that division. Table 4 contains the 

values for shift length by job standardized against division.

2.6 Start Time Variability

Start time variability refers to the consistency in the start time of work periods over the work 

cycle. Examination of the raw data in Appendix A is one means to determine the extent to which 

there is a regular pattern for a given job. Alternatively, the start times associated with each job 

can be displayed graphically. Figures 8 through 14 contain graphical representations of the shift 

start times for each job by division. Based on these graphs, the CDL and BUF divisions appear 

to have the greatest variability in start times. Two jobs in the CHAR division (ECW-06 and 

ECWR-2) also have variability in their start times.

Raster plots offer an alternative means of visualizing start time variability, as well as the pattern 

of the work periods for a job. A sample raster plot is shown in Figure 15. (Appendix B contains 

raster plots for all 39 jobs.) In this representation of a job, the vertical axis corresponds to the 

days of the week and the horizontal axis indicates the hour of the day. The black horizontal bars 

represent the work periods that make up the job. Consecutive days are represented on the 

horizontal axis so that overnight work periods are apparent. The raster plot is also useful for 

determining the regularity in the work pattern of a job. Based on a visual inspection of the raster 

plots, 17 of the 39 jobs have regular work patterns with work periods occuring at the same time 

on each workday.
