Im not sure if others have reported this before but the resistor fans that blow when power is applied cut out too early when power to the motors are cut. They stay on for about 15 seconds and then cut out when stationary or coasting when in reality it should be continued for at least one minute and then stopped. The AI trains though in service mode loop the fan sound when stationary which is realistic but not for the player trains so this could do with a fix if possible. This change would only have to be made when using the dynamic break system though but if you just use the disc brakes then this won't really matter much.
