Generation of Simulations

The PC-Rail Plus software includes a facility to generate working PC-Rail simulations, incorporating two components:

  1. Your data: the data which you have created  using the PC-Rail Plus (or previous Data Builder) software, or otherwise
  2. You (the owner of the data) may copy and share this data as you wish, as long as no charge is made.

  1. PC-Rail simulation software: the software required to run the simulation using your data.
  2. The copyright of the simulation software is retained by its author, John Dennis, in the name of PC-Rail Software.

    The owner of the data is granted a licence to generate a working simulation using the PC-Rail simulation software for unlimited use by him/herself only.

Distribution of Simulations

By using the facility to generate a working simulation, you agree to take all possible steps to protect the software from unauthorised use, reproduction or distribution. Copies of the completed simulation may be distributed only with the express agreement of PC-Rail Software.

In appropriate cases, an agreement may be made with the owner of the data for PC-Rail Software to distribute the completed simulation, with an appropriate proportion of any sales income being returned to the data owner, or a charity of his/her choice.
