What is the minimum burial depth for pipe under railroad tracks?

• A. 2 feet
• B. 3 feet
• C. 4 feet
• D. 5 feet

Answer: (C)

The minimum burial depth for pipe under railroad tracks is 4 feet. This specification is crucial because it ensures that the pipe is adequately protected from the potential impacts and vibrations caused by heavy trains. A depth of 4 feet helps prevent damage to the pipe due to settling or shifting of the ground, which can occur over time due to the weight and motion of rail traffic. Additionally, this depth helps maintain the integrity of the fire service mains, ensuring they remain functional and reliable, particularly in emergencies when fire suppression systems need to operate without failure. Proper installation practices following the NFPA 24 standard are essential for preserving public safety and the effectiveness of fire protection measures.
