Overview
The Little Engine That Could is a 2011 American computer-animated adventure film based on the 1930 story by Watty Piper.
Plot
In Dream Land, Little Engine is a shunter who dreams of becoming a Dream Hauler and bringing dreams to the Real World. She tries to pull boxcars for Big Locomotive, but ends up causing traffic for the other engines, and the Tower reminds her she is only supposed to pull one boxcar at a time due to her small size. Little Engine later gets encouragement from Rusty, an old and wise engine.
In the Real World, a boy named Richard is antagonized by two bullies, Scott and Stretch, who steal his grandfather's pocket watch. Richard flees to the park, where he encounters a train and takes shelter in it. Rusty, who is pulling the train, is unaware he is inside and returns to Dream Land with him. Richard's presence in Dream Land causes the tunnel to it to collapse, trapping him and the trains in Dream Land. The Tower sends some engines to start digging out the tunnel and is forced to demote Rusty to a track-cleaner, much to Little Engine's dismay. She then offers to get Richard back to the Real World and the Tower agrees, promising to give Rusty his job back afterwards.
While searching for the old tracks over Dream Mountain to the Real World, Little Engine and Richard are chased by the Evening Express, who cannot slow down to avoid hitting them. It knocks them down to the hills, but they manage to get back onto the tracks. There, they find the birthday present train, which had derailed when the tunnel collapsed. Little Engine decides to take the train to the tunnel herself and attempts to get the other engines to take the train on the old tracks, but the engines don't believe the tracks exist, so Little Engine, Richard, and the toys decide to go themselves.
