Train Shut down?

Just wondering, i noticed that sometimes in driver mode it says you can shut down the loco and then start it up again? but it never works - whats the situation with that feature. I have tried to remove the driver from the train too.

Thanks

This will only work with certain locos which have scripted engines - off top of my head can't remember which ones

They are the locos made by
Phil_c. There are two built into 06 but the rest are payware.
