" Well since we are going to take these passengers to Knapford,when we get there we are going to ask Sir Topham Hatt if we can cut away the weeds from around Glynn and take him to the Steamworks for "
Victor to fix him so he can run again. — Jacob, Back In Service, season 1
" What's wrong guys?""
"Oh, nothing. We're just a little homesick." "But, Ms. Sierra, how could you be sick of a wonderful place like Sodor?" "No, Toad homesick means that we miss our home, not that we're sick of yours." "Oh, sorry, Mr. Jacob." "That's alright, Toad. After, all you gave us a good laugh. — , Sierra, Jacob, and Duck Toad, Homesick, season 1
" I don't think it's very wise of Mr. Hatt to leave those two immature children in charge of us.""
"They're not children anymore, Marie. They're 16 now." "And anyway, they've been on Sodor, taking care of themselves for like 3 years now. I think if they can take care of themselves for that long, then they can certainly take care of all of us for a week." "They're still young, and they surely aren't responsible enough to take care of a railway as big as this one." "I hate to admit it but, Marie’s right. This railway should not be left in the hand of two incompetent and irresponsible children. — Marie, Rosie, Madison, and Rose about Jacob and Sierra, The Substitute Controller, Season 9
" I can not believe those two are rude enough to say those things about Jacob and Sierra.""
"I know! It's so inconsiderate!" "It is indeed! Someone should say something. I think it should be Gor-" "I'll do it. Jacob is my best friend, after all. — Edward, Henry, James, and Duck upset with Marie and Rose, The Substitute Controller, Season 9
" I wish I could travel the world."
— Jacob, The Search for the Missing Friends

— Jacob thinking he won't be able to follow his dreams, Dreams, Season 12
