A '''train simulator''' (also '''railroad simulator''' or '''railway simulator'''<!--redirects to this page, do not remove! -->) is a computer-based [[simulation]] of [[rail transport]] operations. They are generally large complicated software packages modeling a [[Three-dimensional space|3D]] [[virtual reality]] world implemented both as commercial trainers, and consumer [[computer game]] software with 'play modes' which lets the user interact by stepping inside the virtual world. Because of the near view modeling, often at speed, train simulator software is generally far more complicated software to write and implement than [[flight simulator]] programs.
