600 copies pressed, 400 of which came on black vinyl and in a regular sleeve with the regular artwork (this), another 100 on yellow vinyl came in plain black sleeves with prints of the frontcover (different artwork) and back-cover glued to it, this is also hand-numbered out of 100 on the sleeve's back. This version is called "Train#1-gone" edition. And then there's the "P. Trash Club" edition on transparent clear vinyl with red sprinkles. This one, which - as the name suggest's - was only available to P. Trash club-members, is housed in recycled / natural sleeves (100 made and individually hand-numbered as well).
There's also a <a href=http://www.discogs.com/Useless-Eaters-Zulu/release/3267497>cassette-version</a> that was released a couple of months prior to the 12". It has four songs more than the vinyl-version and a slightly different track-order.
