I can only echo everyone else’s comments. Alan has always been one of the most knowledgeable and helpful railfans out there to those new to Amtrak or to New York area trains. On my first transit-focused visit to New York, we rode Metro North way out to the end of one of the branches in CT. We also did a big New York subway tour.
On another visit, we met up just to go to a Mets game the year Shea Stadium closed.
And one more fact that folks may find interesting (and, all these years later, I’m still kicking myself for not taking a photo of the occasion): Back in 2006-ish, when Amtrak ran the last-ever Metroliner service NYP-WAS (this was actually the *for-real* last Metroliner, because they had retired the service once, but then had to bring it back in an emergency when Adelas were grounded due to some fleetwide mechanical design problem), Alan and I rode the trip in first class. Anthony was supposed to join us, but he got held up by a slow-moving ticket line in Boston and missed the train that would have got him to New York in time. We did meet up briefly with another AUer. When we finally pulled into WAS, Alan followed me out the door and onto the platform, giving him the distinction of being the last first class passenger to ever disembark from a Metroliner train.
From the first meeting and tour of New York, to the last time I saw him, in Denver a couple of years ago, he’s always been a class act and a good friend. Alan, don’t worry about us down here. You’ve done your work, and you did it well.
