Rails not correct after updating Server

[Lilo]

I updated my server and now all my High speed tracks are regular tier 2 tracks, is that because of changes? It rather sucks since my server was basically a Minecart station with many tracks to different places and I'll have to replace about 98% of the cart system. Any possible way to fix this or do I have to manually fix all my tracks?

Oh, and I see wooden booster track and H.S. booster track, is the tier 2 booster called powered track now?

Yes, the railcraft mod was updated in the latest build of Tekkit. This problem however is rather strange. Apparently, Railcraft has confused the Block ID's. No, there is no way to fix this unless you restore your server to 3.1.2 and use a previous world backup.

I am using the build 3.1.2, but it seems I'll have to manually change them all, ty
