First-class Carriage is a magazine story.
One day, Toby has left the quiet quarry line where he usually works to visit the Main Station with Henrietta. As they trundle along, Gordon speeds past with the express. He is pulling a line of first-class Pullman coaches. Henrietta thinks it must be splendid to be an express coach! Soon Toby caught up with Gordon, who was waiting at a signal. He tells the big blue engine what Henrietta had said. Gordon tells Toby that he might pull her along sometime as a treat.
When Toby and Henrietta arrive at the yard, Gordon was waiting to take the midday express. Unfortunately, one coach had to be uncoupled for repairs and there were no other spare carriages. Gordon suggests that he could take Henrietta; the Fat Controller and Toby agree. Henrietta was delighted as she was coupled up to the express. A lot of passengers were excited at the thought of travelling in an old coach too. By the time the last passenger had gone, Henrietta began to feel dizzy travelling at Gordon's speed. On the way home, her coupling breaks and Gordon arrives back at the Yard without her, much to Toby's concern. The Fat Controller saw the broken coupling and sent Toby back up the express line to fetch his faithful coach. Henrietta doesn't want to be an express coach any more!
