PROGRAMMING MAINTENANCE
A track supervisor with a wealth of technical information, given the advantages of enough well-trained
crews and adequate equipment and supplies, should be able to maintain his track in excellent condition.
However, he will fail if he does not plan his work in advance. A program based on remedying weaknesses when
and where they appear is haphazard and bound to result in track of variable condition and poor quality. Some of
the steps of programming maintenance work are outlined in the next four paragraphs.

OBJECTIVES
One of the most desirable features of a railroad subdivision is good uniform quality. A subdivision made
up of alternate stretches of carefully and poorly maintained track is worthless because its capability is limited to
that of the poorest track within its boundaries. There will rarely be enough men and material to maintain a
railroad perfectly. Therefore, any effort used to build up to perfection the quality of one particular section must
usually take away from another. Careful long-range planning and preparation can eliminate the danger of
duplicating work and make it possible to achieve uniform-quality track with a minimum amount of men and
equipment.

PROGRAMMING FOR THE SEASONS
Experience and common sense have led most railroads to follow similar programs of determining what is
to be done and at what time of the year. The details of these programs depend on the
