Yes I agree! but I was asked the question by a friend who works on the railways...I have quoted it: "On our electric trains we have traction systems. (five systems on a eight coach train). We have to connect to each one using a RS232 lead. This downloads any faults the traction system has had. We then save it from the laptop onto a 3 1/2 floppy. Our laptops use windows 95 and are old. We have a new type but don't want ot use it as it will get damaged. Once the logs are saved on the disk we transfer them to the computer system to be run through a macro to highlight faults. Our train is eight coaches long but in effect two units of four coaches. Therefore we have to go to the middle of the train and open a cupboard up inside to plug the lead in. Once we have downloaded the logs of one unit we move to the next coach and do the same. Other train builders have put gps systems in which send info back to the depot for instant checking. Alas we are no where near it. Would you know of any antennas or aerials etc we could plug into the 232 ports of the coaches in the middle of the train and transfer data back? Either to the laptop at the end of the eight coaches or better still a computer in our office when the train has arrived back to the depot?"
So, I was just trying to fathom it out really, but like you say, probably a waste of time!
