How many people are on the train at the first stop? ** At the first stop 172 people - 47 people = <<172-47=125>>125 people are on the train.
How many people are on the train at the first stop? ** Then 13 more people get on increasing it to 125 people + 13 people = <<13+125=138>>138 people.
How many people are on the train at the next stop? ** At the next stop 138 people - 38 people = <<138-38=100>>100 people remain on the train.
