I have been told it's an advanced driving technique, and I can see the point.
The purpose of using your indicators is to signal to other road users (including pedestrians) where you are going. If there is no-one around there really isn't any point signalling. Previously I raised the point that you might have failed to see someone, but the response was that a failure to see indicates a failure to look in the first place. Given that one of the pillars of advanced driving is observation, if you feel the need to indicate "just in case" there has to be a question mark over your abilities to see and observe what is going on around you.
Enfield Lock is a good example on when drivers don't use horns (another reason why I hated NXEA) as people are often in front of the yellow line and the trains come in oblivious to the people on the platform. The drivers never sound the horn and I think it's a bit awkward, too with a level crossing next to it.
That's just so much rubbish.
Enfield Lock is on a dead straight piece of track with a CCTV monitored crossing equipped with full barriers and a station footbridge (I believe there may also be a pedestrian underpass associated with the road crossing). In the normal course of events there simply is no need to sound the warning horn because there is more than adequate warning of approaching trains for anyone who cares to look over their shoulders.
Most people who are over the yellow line quickly move back when they realise a train is approaching and don't need the additional warning of the horn. But if someone fails to move back over the line they will indeed get a good long blast.
If you believe that this is insufficient, please can you outline your reasons.
