If you place down a ghost train and try to copy settings from another train using shift click onto it, the color will copy, but the settings themselves will not. You have to wait until the train is fully placed before you can copy settings.

Thanks for the report. This is currently working as intended. Since ghost trains are not fully connected to other ghost trains and or real trains, pasting settings onto one of them would not update any other ghost trains nearby, or other real trains nearby, and would result in a mix-mess of different schedules on the entire set of rolling stock.
