Unless things have changed, if the main operating type from a base was cleared to take the barrier, then the departure end was generally left up if the a/c had no other means of stopping in an emergency. Now that most fast pointy things have hooks then things are different. For types that are not cleared into the barrier such as the Tucano, then the barrier is (or should) always be down. It was not unknown for ATC to get it wrong and raise the approach end barrier by mistake, this certainly happened with a Lightning and I believe a Javelin.
