Burnaby Central Railway is a small but memorable family stop: a ride-on miniature railway operated by the British Columbia Society of Model Engineers. The trains are large enough for passengers, small enough to delight children, and detailed enough that adults with any weakness for railways will start asking questions.
It is seasonal and weather-dependent, so check operating days before promising it to children. When open, it pairs well with nearby parks and gives Burnaby a local, hands-on attraction that is quite different from malls, viewpoints, and standard urban museums.
