Well, at least it's a working title. Trackside with VIA: Research and Recollections. Keeping the same prefix as the rest of the series, but the second part changes. Alliterative. Meaningful to me, because that is how I can classify just about everything that's going into this book.
Research - done by me or my knowledgeable contributors. Summaries of data, delving into a bit of VIA history, finding a niche undiscovered. Not necessarily scientific research, but data-mining and presentation in useful form.
Recollections - this part is a little less clinical and a lot more personal. Trips and trains, trackside and on board. Things that are in my recall and that should be shared.
So there we have it. Research and Recollections! It somewhat rrrrrrrolls off the tongue.
