Thanks for bringing this to our attention Sarahagain, we have recently changed the website and as a result the url for the blog got altered from new-blog to the-chris-leigh-blog and as a result its knocked out all of the urls for the individual posts, these should now all be working again.
In terms of the newsletter email you received, the USA tank article is in the ‘Know Your Stuff’ section of the magazine whereas the tips cards that you were redirected to are the ones that we trialed on the inside flap for a few issues in 2017. It is one of these things where I wrote the copy for the newsletter and it has been altered to fit in the neat little square box! For those who do want to know how to put a DCC decoder into their USA tank, Chris Leigh takes them through it on page 74 of Model Rail 248. (CG)
