OK, it's done as a SW9/SW1200 (actually numbered for a SW9) and has been approved for release...

One issue though, it won't work if the original free kit is installed... I can't figure out how to redirect the .GeoPcDx file to my own folder.
Edit: The reason the model being released is the two stacker: The files to create the single stack model are part of Britkits Xtra payware pack for the SW1200.
I have permission from Mr. Richard Cowen (Britkits) to release models based on the freeware download, but must leave out files that come from the payware release.
If you want, I can put together the SW1200-F MU equipped switcher as a manned/unmanned pair, a TR5 cow and calf (1811 and 1811B), and a SW8 single stacker that will all require the purchase of the payware pack from Britkits to create properly. Please, let me know if there's a want for them.
