If you were doing a hobbyist project, sure. With something like this which has safety implications, there would be a lot of recertification required, not only of your software but also of the new hardware that it will require. This is not trivial, and would be very resource intensive. And don't forget that you have to roll out the new hardware to the trains. Or - you can use the existing Win3.11 systems, which are apparently still working just fine, and just update and test a single application. I can lend you my Petzold, if you like.
