Traper2TM is a train simulation software package that provides a powerful, cost effective tool for modelling train operations, ranging from simple haulage tasks through to multiple interactive journeys.

Features include a simple, intuitive user interface that allows for easy navigation through menus with fast access to vehicle libraries and track information.

Traper2TM uses engineering first principles applied to individual rail vehicles that are constructed with four degrees of freedom; position, velocity, brake pressure and engine power. The values of these variables are traced through time using complex numerical integration techniques. Driver ability has been modelled to replicate real scenario behaviour as determined through extensive testing and validation.



Traper2TM functionality has been expanded to enable accurate modelling of the effect of additional capabilities such as:

  • AESS
  • Alternative resistance formulas
  • Animation
  • Consist manager
  • Coupler type
  • Different adhesion levels
  • Distributed power
  • Driver capability
  • EcoRunTM
  • ECP Braking
  • Mixed consists
  • Trip Optimiser

Traper2TM has been extensively tested and validated against real train operations to provide accurate and reliable outputs.

Traper2TM simulation package provides train performance outcomes with a higher degree of certainty and allows a flexible platform for future development.


The quality and volume of information provided from Traper2TM simulations is now significantly improved with interactive graphical representations provided for most aspects of train operation. 

This information can be used to assess a myriad of outcomes from life cycle cost modelling to in-train forces. Traper2TM provides graphical results for the following:

  • Adhesion
  • Air Brakes
  • Coupler Forces
  • Dynamic Brake Force
  • Energy
  • Engine Power
  • Fuel
  • Notch Histogram
  • Sectional Run Times
  • Speed
  • Station Locations
  • Track Elevation and Curve Profile
  • Tractive Effort
  • Train Acceleration

The graphically represented results enable easy analysis and assessment for specific train operations. This in turn provides benefits by identifying ways to optimise fuel usage, section times and throughput whilst providing valuable data to ensure the protection of the rail asset itself.
