Plot
A passenger train arrives at Gower Gulch station, where Tweety is entrusted to the conductor's care. Sylvester, eager to catch Tweety, faces obstacles from the vigilant conductor. Despite warnings, Sylvester attempts to reach Tweety, triggering chaotic antics aboard the train. As Sylvester's pursuit escalates, he encounters a bulldog named Hector, leading to a series of comedic clashes. Sylvester's repeated failures to catch Tweety result in mishaps, including a near collision with the train's furnace.

In a final attempt to claim Tweety, Sylvester disguises himself and manipulates events, only to find Hector instead. A frenetic chase ensues, culminating in Sylvester's defeat and Tweety's observation from the train's caboose. Sylvester ultimately and unwittingly transports Hector instead of Tweety, leaving Tweety lamenting the loss of his playmate.

Production notes
The film title is an adaptation of the familiar train conductor's call, "All aboard!" The instrumental theme used to underscore the motion of the train is "On the 5:15".
