In overhaul quantity calculations, how is overhaul distance measured?

• A. in miles
• B. in feet
• C. in stations
• D. in meters

Answer: (C)

In overhaul quantity calculations, distance is measured along the alignment using stations. A station is a 100-foot interval, and locations are written in station notation (for example, 12+34 means 12 stations plus 34 feet into the next station). This unit is used because it lines up directly with plans and staking reference points for long, linear projects like tracks or roads, making it easy to compute lengths and connect measurements to drawings.

For instance, moving from station 12+34 to 15+78 covers 3 stations (300 feet) plus 44 feet, totaling 344 feet. Using stations keeps the reference system consistent across the entire project, which is why it’s the standard unit for overhaul distance.
