Vertical alignment design to Network Rail L2/TRK/2049. Scope:
- Gradient design (1V in N ruling, 1V in 200 minimum)
- Vertical curve radius (R = V² / 4.4 minimum, hollows and humps auto-detected)
- Sags and summits
- Jointed vs CWR (continuous welded rail) treatment
- Level crossing vertical design
- Tunnel and overbridge clearances
Outputs include long-section drawings, gradient profiles, and tamper chord analysis.
