HVRII is alot better as it has better graphics and has sound aswell there are somethings the second version doesn't have like the first one,but you can do elevated tracks but you can't add points to elevated track,you can add hills, tunnels,rivers,lakes,mountains,but it does't have a turntable in the program which is a shame as it would of been great to have one.
Here's afew screen shots of layout i have done in HVRII.
