Well it seems that after some tweaking exe has bowed to the pressure social pressure and demands, Minecarts are back in, I'm not sure how stable the code is, but I tested it and all seemed well! version 0.3c (aptly named 'c' for cart...) is already available at a file share site > > HERE <<
This new version [release date 2011-01-24] also contains further optimisations to help reduce lagging issues which came about with Ver 0.3
So.. go forth and let there be minecart tracks !!!
