Matt - I believe it was released as a direct download from Davids website, which he then took down - the upload was for a public "beta", although not much in the way of testing was done, as all the gimmie pigs downloaded it without a word of thanks. I trialled it on a two baseboard module, and couldn't fault it, but as electric traction wasn't my thing, I didn't take it any further than that. I imagine it will be on the DLS eventually though, along with the double track version and any other bits and bobs to go with it.
