For fifty years I have been playing fantasy timetables, using computers for the last 40. Never finished anything! Lots of scraps in long-forgotten computer languages.
I'd be interested in sharing ideas with anyone who wants to develop home-brew software.
In particular, I'd love to get hold of digital gradient profiles. Does anyone have any? I have half-finished software to scan graphical gradient profiles and digitise them if anyone wants to encourage me / help me to finish it. Although this is less relevant now, when modern trains have enough power and kinetic energy to flatten all but the longest, steepest climbs.
Anybody else out there interested?
What languages have you been working in?
