The realism of today's latest simulations is extremely impressive.
Modern simulators now let you climb into accurately modelled cabs and drive a great variety of incredibly lifelike trains in full 3D virtual landscapes. Train Simulation hasn't been around for quite as long as Flight Simulation, but since the arrival of the Train Simulator and Train Sim World series of sims, rail enthusiasts have really begun to get excited about train simulation. Driving trains on your home computer can be a hugely rewarding and enjoyable experience which will also improve your understanding of real-world rail operations.
