[QUOTE]Originally posted by Geoff Mayo: [QB] [QUOTE]Originally posted by Gilbert B Norman: [qb] While avoiding speculation with regards to the instant matter, there are many a case of an Engineer "forgetting where he was" and involving passenger trains.[/qb][/QUOTE]It's human nature - how many times have you been driving along a freeway and suddenly wondered where you are? Fortunately rarely a problem on the roads but a different story when driving a train. Both ERTMS and PTC have a display that shows what's coming up - whether a signal, a grade change, a speed limit. The PTC version I've seen scrolls left with the train in the bottom left. The ERTMS version scrolls vertically downwards with closer items taking up more of the display than items further away (logarithmic?). [URL=http://www.itcgroup.cz/aitom/upload//web/fotografie/it_ansaldo_sts/thumbs/th_ansaldo_bordo_800x600.jpg]Sample ERTMS display[/URL]: the "upcoming" bit is the block to the right with the 0/500/1000/2000/4000 markers. Current speed 134kph, current limit 140kph, no reductions necessary now or in the near future. [/QB][/QUOTE]
