Double heading Lionel 224

Is there an article by Dave Smith about adding a front coupler to a Lionel 224? I have heard of it but can’t find it. Thanks.

The article is in OGR magazine, December 2010.

Here are videos showing the front coupler on my Lionel 2018 steam engine so that I could doulbe head it with a 2035. The construction article should work with the 224 as well as most other steam engines that have a front 2 or 4 wheel leading truck.
