I am a subscriber to Classic Trains, absolutely fascinating read from cover to cover four times a year (a shame over the counter availability in the UK is so poor, hence my sub) and have managed to collect paper versions of most back issues with electronic ones filling the gaps right back to the first issue so I hope they don't mess about with it.
Model Railroader is (usually) available from WHSmiths in the UK when my local hopeless branch bother to stick it on the shelf that is and I have to say, it's not great. I have a copy of the July 1974 MR on my desk at the moment, thick with pages, well written how to articles (I mainly bought it for a brilliant article on paint schemes on SP switchers) and larger pages, the current issue of MR (April 2024) is little more than a flimsy pamphlet.
Trains used to be worth a read but has descended down the same rabbit hole that Rail Enthusiasrt/Rail did in the UK, becoming little more than a thin bottom kissing trade magazine and if it went I would not rate it as a loss, thing is I suspect as has already been mentioned that Trains was the one mag the new owners actually wanted.
I do subscribe to Diesel Era and MRC though, different publisher and the difference in quality over MR is noticeable.
