Nevertheless trains shall not crash in normal operation, so making a train not crash with itself is the best solution for everyone. + +Vehicles not keeping their "maximum" speed [FS#4815]: + Vehicles that have not enough power to reach and maintain their + advertised maximum speed might be constantly jumping between two + speeds. This is due to the fact that speed and its calculations + are done with integral numbers instead of floating point numbers. + As a result of this a vehicle will never reach its equilibrium + between the drag/friction and propulsion. So in effect it will be + in a vicious circle of speeding up and slowing down due to being + just at the other side of the equilibrium. + + Not speeding up when near the equilibrium will cause the vehicle + to never come in the neighbourhood of the equilibrium and not + slowing down when near the equilibrium will cause the vehicle + to never slow down towards the equilibrium once it has come down + a hill. + + It is possible to calculate whether the equilibrium will be + passed, but then all acceleration calculations need to be done + twice. |
