It was 1959 and I had been attending a two-month private school at San Miquel de Allende, Mexico. Steam locomotives were still in wide use in Mexico at that time and I knew that narrow-gauge trains pulled by steam locomotives still ran out of Mexico City. On March 21, 1959, I had the opportunity to be in Mexico City, and I wanted to see and photograph these narrow-gauge trains. I hailed a cab and tried to describe to the driver in my best, but not at that time very good, Spanish what I was looking for. He started taking me somewhere and I realized that he didn't know what I was trying to say, so I had him stop, as we crossed a standard-gauge railroad track. I got out of the cab, walked over to the two rails that were spaced 4 foot and 1/2 inch apart, and held my hands at about 3 feet. The driver had an "ah-ha" moment, realizing what I was asking for, and then drove me to the San Lazaro Station, where passengers boarded narrow-gauge trains, and where the Ferrocarriles Nacionales de México (N de M) had it's narrow-gauge roundhouse and shops. The railroad hands were fascinated with the 17-year old American kid with the camera and were completely obliging. A bar had been set up in the yards in an old box car, and 3 or 4 workers treated me to mescal and pulque while we all laughed and sang!
