I think the suggestion was a solution to drivers using their own makeshift reminders. No one is saying there's anything wrong with that, quite the contrary, I think it is just a suggestion that something could be built into the cab to help you guys and remove the need for you to come up with and use your own improvised reminder aids.
No one is trying the dumb the job down, just suggest innovative solutions to an issue, which to me (not a driver!), seems to have been overlooked by train manufacturers.
It would seem youre all quite happy doing your own thing, so maybe this is a non-issue. I'm just looking at it from an outsider's perspective and coming up with a solution.
Unfortunately, and this is not directed at you but there are managers who have never driven a train who think they are helping with ideas on reducing SPAD issues wanting to put extra reminders in the cabs, this will lead to extra distraction and also the possibility of more incidents. The issue is down to recruitment and training, also down to monitoring by managers. If drivers were monitored correctly, had a anonymous reporting system where they can report near misses (near incidents) at high risk locations, have the balls to tell a manger that they are fatigued or distracted from outside distractions and were not "punished" for an incident but used to help others this would be a good and positive step to reducing safety of the line incidents. There is machinery in place that is addressing this and also Non Technical Skills are now being monitored and put into the training program, not that I personally agree with all of this but it seems that management are waking up to the fact that train drivers are not robots and if they have an incident it is totally their fault. I also think that management should look at incident free drivers that have been driving for 10 years plus and compare their driving skills, preparation for work and their attitude towards the job against drivers who have repeat incidents.
These new innovations for preventing SPADS are not as good as what the drivers currently use, their own methods, find out what drivers who have been driving for over 10 years with no incidents and then maybe you will come up with a solution that works, be it a red card, risk triggered commentary, singing a song by simply red or what ever it may be!
