CHAPTER 6

TRACK AND ROADWAY DESIGN

1. ROADWAY.

a. Definition. The roadway (also called right-of-way) is the strip of land containing the track, ditches,

and other facilities needed for the operation of the railroad.

b. Roadway Width. The roadway must be wide enough to accommodate the track, side ditches,

portions of embankment or cut slopes, parallel service roads, and other structures and facilities necessary

for the operation of the railroad. The roadway must also allow sufficient clearances between the track

and adjacent structures, as covered in chapter 6, paragraph 4. Figures 6-1 through 6-7 indicate the width

required for the basic track structure.
