A driver can travel free whether or not it is work related as long as their travel card allows, usually within TOC's within a group for example. Driver who work for DB have good travel privileges you have ATW, XC, Chiltern, Tyne & wear, Lorol and some busses that are all free, there may be one I missed but I think that the facilities for any DB group staff is excellent.
Are you sure? I am a driver for DB and I don't get (or haven't been told about) free travel. The only 'free' travel I get is when there is a PASS is on my diagram. Even then, I should have my Freight driver's duty pass with me.
The only blokes who get free travel at DB are ex BR.
Unless I'm missing something huge, I've never heard of what you say.

AWS and/or TPWS perhaps, if there's no one in the cab to acknowledge/cancel the warnings then the brakes might get applied a lot.
Was that a guess?
Once the 'key' (BR drivers key on a 60 & 92 or the reverser handle key on a 66) has been removed, it automatically disables AWS and TPWS. The cab is shut down once you remove the 'key'. It disables AWS and TPWS and also drops the train brake to zero (applying the brakes fully).
When a locomotive is hauled DIT (Dead In Train), the driver of the leading loco operates the E70 valve on the loco he is hauling DIT. This is an isolating valve on the brake frame which basically turns the locomotive into a wagon in braking terms. So when a 92 etc is hauled by a diesel, the E70 is isolated and the braking control goes to the loco hauling the train. The hauled loco becomes in effect a wagon with the braking characteristics of just another wagon.
