The first to pass us in our carriage was a potentially fractious pair of toddlers, Beanie and Cecil (not their real names). Even were we to plan future excursions not to overlap with national school breaks, I realized there’d still be no guarantee to avoiding the likes of a pair of screaming two-year-olds who believe trains were made for running up and down the aisles, depositing candy floss to armrests along the way.
