Plan the railway.
Build it right.

Five practical calculators for Trainz route builders. Values update instantly, stay on your device and can be changed as often as you need.

01
Track geometry

Gradient converter

Enter any one gradient format and convert it into the values used in Trainz and railway diagrams.

Change any field—the other two update automatically.

02
Route planning

Grade & elevation planner

Calculate the grade required to move between two elevations over a known horizontal distance.

Height change10.00 m
Trainz grade1.667%
Railway gradient1 in 60.0
03
Route planning

Required track length

Find the minimum horizontal distance needed for an elevation change without exceeding your chosen grade.

04
Track geometry

Curve radius

Estimate the radius of a circular curve using its chord length and centre offset.

Curve radius260.00 m
Arc angle45.24°
05
Track geometry

Superelevation

Calculate the Superelevation Degree and Superelevation Limit values used by Trainz, following the N3V calculator.

Superelevation160.0 mm
Superelevation degree p156.4322
Superelevation limit p20.1115 rad

Enter the p1 and p2 results into the corresponding Trainz track-spline properties.
