Just make it from scratch?
For sure there is so much useless shit in there, that's why nobody gets their head around it anymore.
Just make it from scratch?
And miss some tricky edge cases, which were covered in old code?
It's a railroad. Those edge cases could be disastrous.
Ok, keep it for the next 100 years and get custom build hardware which can run that stuff, that's cheap and safe.
Never touch anything
No. What I mean is rewriting it part by part, not from scratch, but following the old algorithms as possible.
As long as it's not à la Musk where the new versions will be inferior to the previous one because "no modern trains should rely on antiquated technology so we're scrapping everything from before to start from scratch".
