Installation of segregation fencing between rail tracks requires precise coordination with rail operations, strict safety protocols, and specialized installation methods. Production rates vary based on fence type, track spacing, and access conditions. Modern lightweight materials and rapid deployment systems have improved installation efficiency.

Note 1: Production rates are indicative only.
Note 2: Rates vary based on:
- Track spacing
- Access conditions
- Train frequency
- Weather impacts
- Installation method
- Safety requirements
Note 3: Installation calculation formula:
P = (BR Ć TF Ć AF Ć WF) – SC, where:
- BR = Base rate
- TF = Track factor (0.8-1.2)
- AF = Access factor (0.7-1.0)
- WF = Weather factor (0.8-1.0)
- SC = Safety constant
