Fifty-five years ago, my grandmother — Grandma, always — took me on a train ride from San Antonio to Austin. I found evidence of it tucked away in an envelope at my mother’s house some time ago.

Grandma thoughtfully made a note of the fact that it was my first train ride, and the date: July 8, 1967. I was visiting Grandma for a while that summer, as I did in the years before we lived in San Antonio.

Come to think of it, the next summer while I visited her, my family moved from Denton to San Antonio. (Not the stuff of a sitcom; I knew perfectly well we were moving.) Grandma was the one who first took me to visit the house that my mother had bought, and would live in for nearly 50 years.

I find it amusing that a child counted as half a person for the purposes of train fare. Grandma thus paid fare $4.41 for one and a half riders. Adjust that for inflation, and she paid more than $38 in our current, beleaguered dollars.

Good old Missouri Pacific. Mopac.

We must have been visiting someone she knew in Austin, but I don’t remember anything about that. I do remember wisps from the ride itself, mostly the view out the window. I’m sure she knew a train ride would be a thrill for a six-year-old.

But there was more to it than that. I also remember that she told me that it might not be possible for me to ride a train when I was older, so she wanted to take me. Certainly Grandma knew, by 1967, that the writing was on the wall for U.S. passenger train service, or at least Mopac. Maybe she wanted a last ride herself, before passenger trains went the way of the buffalo.

(Outdated analogy. Like the buffalo, passenger trains came to a population bottleneck known as Amtrak, rather than total extinction.)

I imagine an older version of myself — not even now, but perhaps from mid-90s — appearing to her and saying, Grandma, I’ve ridden a lot of trains. In Europe and Asia — and once across Russia from Asia to Europe. I’ve taken the bullet train, and even Amtrak from San Antonio to San Francisco in 1990, though it was distinctly second rate.

And those are just the intercity trains. I’ve lost count of how many different subways and light rail lines I’ve taken, but it would be dozens.

She probably would have been a mite skeptical of those assertions.

It was a one-way ticket. We returned by bus the next day.

Go Greyhound. Grandma also noted that it was my first bus ride. She was being thrifty in not taking the train back, I think. The bus fare is recorded as $1.35 (just short of $12 now), though I don’t know whether that was for the two of us or just me. Even if she paid double that herself, that would have been less than the train.

She probably didn’t think buses would quit running. I don’t remember the bus ride at all.

Future me could pop up again: Grandma, I’ve been on a lot of buses, too, in lots of states and countries. I took one across Australia once. But even in America, I’ve gotten around — all the way from Boston to Los Angeles, once, and that was just part of the trip!

Isn’t that nice, she’d say, thinking at least that her grandson has a healthy imagination.
