A couple of thoughts:
First of all, Mooner, you're very welcome.
@laming: Could you be thinking of Rail (or Railroad) Fiction Classics? This was a yellow hardback with an elaborate locomotive design on the cover. It was followed by More Rail Fiction Classics. Recommended.
@smd4: Clear The Tracks is also excellent.
I'd like to also point out that Double Jacks is reviewed and available on Amazon. Don Francis.
