I have no idea when the Engine Shed is released.
Just out of interest how do you know about it before others Jeremiah?
I got an email today saying it was available.
Well I do check the Hornby website on a daily basis for any updates regarding new releases and sometimes new announcements. I also check the Hornby Forums on a daily basis and provide help wherever I can. "The Engine Shed" is always released in a Friday so it's easy to keep a track of it. When one is released if Adam hasn't posted about it, I simply follow his posting format and make a similar one.
