A tour through Grandpa Bill’s immensely detailed ‘Train Town’ has exploded in popularity online. The video, recorded by Ryan Crets, who used a tiny camera strapped to a model train, takes a seven minute journey through the huge construction. “The whole family has been overwhelmed with the reaction of the internet community to this video. It’s amazing reading people’s positive words about my grandfather’s hard work,” said Ryan. Credit: Ryan Crets.
