San Diego school district apparently has 130,000 students. Probably 200,000 counting suburban schools outside the city.
How many kids are in those “throngs”? What is the capacity of a trolley?
The trolleys seem to run three-car trains, with I’d say a sitting/standing capacity of 100 per trolley car. Say the pertinent period is two hours, and there are eight trolleys per hour on the line during rush hour (apparently frequency is 1x per 7.5 minutes).
100 x 3 x 8 x 2 = 4800 people. Assuming 50% of each trolley car is full of border-crossing students (a high estimate), that’s 2400 kids per day.
About 1.2% of the entire student population of the county. They’re also mostly linguistically homogeneous (Spanish as primary language, vs possibility of local languages only if originating from further south in .mx), so teaching them English should be easy vs a more polyglot student population.
