| However we DON’T have a road network that operates safely with autonomous cars so a claim of “it will work for cars so it will work for trains” is just uninformed speculation. Indeed, there is no guarantee that autonomous cars will ever work in densely packed, complex urban environments. Maybe the reaction against GPS is because some people are clearly uninformed of the reality of what is required for a signalling system and don’t appear to have done even the most basic of research. Claims of “GPS/WiFi has to be on the menu” when a little research will demonstrate that it isn’t. Nothing to do with drivers, more laws of physics. The people claiming WiFi is the answer don’t appear to be aware that even today on the Jubilee and Victoria lines the train driving and stopping is autonomous ( without any GPS and WiFi ..) and the driver is there to close the doors and provide the “if you don’t clear the doors, we aren’t going anywhere” announcements. The projects to resignal those lines also went over budget and time. Some things in life are just inherently complex and upgrading a working railway is one of them. But anyway, it’s all just a bit of banter on a local forum. Nothing I say, or the people who think WiFi is the answer will make the slightest bit of difference to the manufacturers who are producing the signalling products or the operators deploying them. |
