What better way to spend a Friday afternoon than with a quick kit-building project. I received a couple of Walthers Cornerstone 'HO' tank container kits for review and they went together in a matter of minutes. Pre-painted, all you need to do is stick them together and, hey presto! As you can see in the image above, the 'HO' tanks (left) are smaller than C-Rail 'OO' versions (right) so they're no good for 'OO' rolling stock. But they may have other uses, such as filling the outer reaches of an intermodal depot, for example. See www.gaugemaster.com for more details.
