The article's author probably just messed up the math somewhere. According to wikipedia, there were 18,220 daily rides in 1978 on the Edmonton LRT. If he got $900 daily and that's 20%, then there were a little under $5000 proceeds daily, so each ride would have only brought in about $0.25.
I guess most people who ride rail frequently have monthly passes, only those who use it occasionally have to buy tickets at the ticket machine. Also, isn't 25 cents a reasonable price for a single ticket, given that this was 1981?
