I know I'm late to the party on this, but I saw a copy of the June MR with Ron's TP56 article in it, so I bought it.
I must say, it's even better than I expected (and I expected it to be good).
The whole prototype backstory, plus a nice scale drawing, and some really good photos, on top of all the usual
highly-explained step-by-step we have all come to expect from Ron's work here on Railwire, are all presented
in the magazine very thoroughly. I'm glad MR didn't skimp on details or page space with this.
And once again, Ron, congratulations on a beautiful piece of work and article.
