sorry for ask.that's a petition
I really like Railcraft,and I really need high speed ASAP
but I guess that new version might be release in long time.
I really want to build a high speed railway 😄

Unfortunately not... Railcraft is like Harvestcraft which pre-releases (betas) are only available to patrons. We will try to release as soon as possible.

I got it thanks

Due to the breakThings->fixThings->breakThings nature of the dev cycle, Railcraft is in not state to be released publicly at the moment.
