I bought HBL in the sale, and quite enjoying it. However, starting service RB81 11307 from Bad Oldesloe (starts at 7.33), I noticed the starting signal was blank. Contacting dispatcher said 'proceed as signals indicate' - of course if I had followed that advice I'd be waiting a long time - at least here in the UK a signal that's out is treat as a red. Upon passing it, it went red, as it should.
