A train going around a curve is accelerating. If you have the tech to negate inertia so little force is required to go around a curve theneradicator wrote: ↑Tue Nov 20, 2018 3:57 pmChemplants don't make engines :p. [/nitpick]
Any society with FTL captable drives should have access to some sort of inertia negation device. Scifi games solve it with magitech. .
Personally i think free-form rails are a two edged sword. Sure you can make some nice things, but it's also infinetly more annoying to build a perfectly neat grid aligned rail system. So a simple s-curve type element would suffice in my book. (As i don't dare to hope for the full 16-segment circle from the original thread.)
why aren't you using the same tech to make the train speed up or slow down on straight tracks?
